FC729 has improved resistance to Cercospora Leaf Spot, Rhizoctonia Root and Crown Rot, and Root Aphid. The FC729 was evaluated numerous disease nursery trials, including Cercospora (4 site years), Rhizoctonia (5 site years), Curly Top (3 site years), Fusarium (5 site years), Root Aphid (3 site years), Aphanomyces (1 site years), and Rhizomania (1 site years). In Cercospora nurseries in East Lansing, Michigan and Shakopee, Minnesota, FC729 exhibited resistance similar to the resistant check. Similarly, FC729 demonstrated Rhizoctonia Root and Crown Rot resistance statistically equivalent to the resistant check FC709-2. FC729 also has moderate resistance to Fusarium Yellows, but is susceptible to curly top, rhizomania, and Aphanomyces. FC729 is publicly released and not protected. Breeder’s seed of FC729 will be maintained by Soil Management and Sugarbeet Research Unit, Fort Collins CO 80526.

The initial selfing occurred from one self-fertile C869 CMS plant (EL-A013483) in 2002. Seed was field grown at the Bean and Beet Farm (Saginaw, MI) in 2005. Roots were harvested, potted into fiber pots, vernalized for 16 weeks, and grown in the greenhouse. Seed harvested from this plant (EL-A018880) was considered the S1 generation, and subsequent generations were derived by single seed descent using field grown mother roots and selfing with the same methods. The S2 generation (EL-A022144) was obtained in 2007, and the S3 (EL-A025943) in 2010. Nine individuals of this population were genotyped with 69 SESVanderhave proprietary SNP markers evenly spaced across the beet linkage map, and a single homozygous individual (#17) of this population was sequenced for preliminary evaluation. A sibling of this line (EL-A026195) with good field performance in Michigan (Saginaw Valley Research and Extension Center, Richville, MI) was selfed in the same manner to yield the S4, while S5 (EL-A13-03870) and S6 generations were produced solely under greenhouse conditions in 2013 and 2015, respectively. Sixteen S6 individuals were genotyped with 24 SSR markers (McGrath, J.M., et al. 2007. An open-source first-generation molecular genetic map from a sugar beet x table beet cross and its extension to physical mapping. Crop Sci. 47:S27-S44.), and six individuals (EL-A15-01096, EL-A15-01098, EL-A15-01099, EL-A15-01101, EL-A15-01102, and EL-A15-01103) were chosen as sequencing candidates based on marker homozygosity and similar growth habit and appearance, for sequencing. One of these (EL-A15-01101) provided the sole tissue source for Illumina sequencing and nuclear DNA content estimation and was named EL10 for germplasm release.

This cross was to develop a population to map sugar beet cyst nematode (SBCN) tolerance - WB242 is considered a source of tolerance. 9933 is rhizomania resistant (segregates for Rz1 but does not have the Rz2 gene marker). This is a base breeding population, random mated and segregating for multigerm (MM), self-fertile (Sf), genetic-male-sterile (A:aa), but is 100% green hypocotyl (rr). It is moderately resistant to aphanomyces root rot and to cercospora leaf spot. It shows moderate resistance to powdery mildew, beet curly top and virus yellows . A single F1 seed was selfed to produce seed of an F2 family. Those seed were grown out in the greenhouse producing 125 plants, from which leaf tissue was collected for later DNA extraction and genotyping. Of the F2 plants, 25 bolted without vernalization and were bagged to prevent cross-pollination. The remaining 100 plants were vernalized for 120 days and then allowed to put up flower stalks and were bagged in the greenhouse to prevent cross-pollination. These populations were the selfed seed of the 125 F3 families from the original cross. Using SNP markers linked to Rz1 and HsBvm-1 (SBCN resistance), leaves from F2 plants were genotyped, and those which had markers indicating homozygous resistance to both Rz1 and HsBvm-1 were chosen. There were 17 F3 families selected and bulk increased in the greenhouse. There were 570 biennial plants which became seed production 20131058, and 62 annual plants which became 20131058B_. Seed production 20131058 was bulk increased in the greenhouse, and seed from 52 biennial plants became 20141038PF, the F5 generation of this population. Seed from 20131058B_ also was bulked increased and seed from 93 biennial plants became 20141040. 20141038PF was increased in the field as 20171002PF.

Each population was selected initially for characteristic sugarbeet plant and root characteristics and subsequently for sucrose concentration. All eleven germplasm lines are multigerm, diploid, biennial lines that produce roots with white skin and flesh. All eleven lines have tapered roots with a relatively narrow grove, minimal branching, and non-protruding single crowns. Hypocotyls of F1054 are red. The 2-year average sucrose concentration of the eleven germplasm lines was 88% of the sucrose concentration of an adapted variety (ACH-817). The sucrose concentration of F1054was 95% of the adapted variety. The 2-year average root yield of the eleven lines was 76% of the root yield of the adapted variety.

| 22 | PI 683513 | 'KDH4-9' | Beta vulgaris L. subsp. vulgaris | Idaho, United States | W6 | | | 2017 | DEVELOPED | PRE 2017 | | | | | Breeding material | KDH4-9 is exceptionally resistant to Beet curly top virus (BCTV) strains; Cal/Logan (CA/Log), Severe (Svr.) and Worland (Wor) that are vectored by the beet leafhopper (Circulifer tenellus). KDH4-9 plants were subjected to infection by BCTV at the four-leaf growth stage, under controlled conditions in greenhouse and compared to other resistant genetic stocks and commercial cultivars. This line showed minimal leaf curling and vein clearing. These symptoms are very mild compared to all resistant materials included (including KDH13-PI663862) in the experiments. Additionally, later towards maturity of the plant new leaves did not show any symptoms. The resistance of KDH4-9 was confirmed in five greenhouse experiments and three field experiments. The field evaluations wer carried out in the Beet Curly Top nursery in Kimberly, ID. KDH 4-9 is homozygous for green hypocotyl, has light green upright and narrow leaves, and a small compact canopy. KDH4-9 can be used as a donor parent for curly top resistance genes in hybrids, backcrossing, and employed in genetic studies. KDH4-9 is a monogerm, self- fertile, and requires at least 90 days of vernalization to induce flowering. This line is highly susceptible to rhizomania, and susceptible to Rhizoctonia root rot, Cercospora leaf spot and Fusarium yellows. The initial ovule culture work on the USDA-ARS genetic material was carried-out under contract by a private tissue culture laboratory. | 1953782 | PI 683513 |

KEMS06 segregates for hypocotyl color (70% rr), and has light green narrow leaves, long slender petioles, open canopy, and a normal tap-root. KEMS06 is self-fertile and segregates for multigerm seed. KEMS-06 has been evaluated for two seasons for agronomic traits and screened for sucrose content and response to diseases such as Cercospora leaf spot (CLS; caused by Cercospora beticola), curly top (caused by Beet curly top virus: BCTV), rhizomania (caused by Beet necrotic yellow vein virus; BNYVV), Rhizoctonia root rot (caused by Rhizoctonia solani), Fusarium yellows (caused by Fusarium oxysporum f. sp. betae), and postharvest fungal root rots (caused by Botrytis cinerea, Penicillium spp., and other fungi). KEMS06 was evaluated for CLS resistance through an artificially induced epiphytotic in the field and Fusarium yellows resistance in a well-infested seed company field nursery for two seasons (2015 & 2016). The results indicated that this line carries better CLS and Fusarium yellows resistance than the commercial resistant checks included in these nurseries. Additionally, KEMS06 line was evaluated for rhizomania resistance in the USDA-ARS- Kimberly, Idaho field nursery for three seasons. The line had normal leaves and not the narrow upright yellows leaves associated with susceptibility to BNYVV infection. However, some hairy secondary roots were observed but no bearding or constricted roots were evident. This line showed superior storability with minimal fungal root rots after 4 months of indoor postharvest storage at 1.1oC temperature set-point. This line is susceptible to BCTV and R. solani. We suggest that this line is a suitable parental line as donor for resistance to CLS, Fusarium yellows, and storage fungal root rots. | 1953783 | PI 683514 |

The main difference between KEMS06 and KEMS06-600 is that the later has larger canopy and tap root. This line is self-fertile and segregates for multigerm seed. The line has been evaluated for the following traits: sugar content, resistance to Beet curly top virus (BCTV; causes curly top), Beet necrotic yellow vein virus (BNYVV; causes rhizomania), Cercospora beticola (causes Cercospora leaf spot; CLS), Fusarium oxysporum f. sp. betae (causes Fusarium yellows), and postharvest fungal root rots caused by Botrytis cinerea, Penicillium spp., and other fungi. KEMS06-600 was evaluated for CLS resistance under artificially induced epiphytotic and resistance to Fusarium yellows in naturally infested well-established seed company field nurseries, for two seasons (2015 & 2016). The results indicated that this line carries better CLS and Fusarium yellows resistance than the commercial resistant checks included in these nurseries. Additionally, the KEMS06-600 line was evaluated for rhizomania resistance over three seasons in the USDA-ARS- Kimberly, Idaho, field nursery which is routinely used for screening commercial sugar beet varieties for resistance to BNYVV. The line had normal leaves and not the narrow upright yellow leaves associated with susceptibility to BNYVV infection. Low levels of hairy secondary roots were observed, but no bearding or constricted roots were found. This line showed superior storability with minimal fungal root rot after 4 months of indoor storage at 1o C temperature set-point. This line is susceptible to BCTV and Rhizoctonia solani (causes Rhizoctonia root rot). We suggest that this line is a suitable parental line which can serve as a source of resistance for controlling CLS, Fusarium yellows, and storage fungal root rots. | 1953784 | PI 683515 |

KEM08 is a S5 multigerm line and homozygous for green hypocotyl. The line has a large compact erect canopy, smooth broad leaves, a normal size tap root, high sucrose content (up to 18%), and an average root yield of 58 tons per hectare in two seasons under optimal field conditions. KEMS08 was evaluated for Cercospora leaf spot (CLS; caused by Cercospora beticola) along with KEMS06 and KEMS06-600 under artificially induced field epiphytotics and in another seed company nursery naturally infested with Fusarium oxysporum f. sp. Betae that causes Fusarium yellows for two seasons (2015 & 2016). The results indicated that the KEMS08 line carries better resistance to CLS and Fusarium yellows than the commercial resistant checks and both KEMS06 and KEMS06-600 lines. Additionally, KEMS08 was evaluated during two seasons for resistance to Beet necrotic yellow vein virus (BNYVV; causes rhizomania) in the USDA-ARS- Kimberly, Idaho, field nursery routinely used for screening commercial sugar beet cultivars. This line had a uniform mild leaf yellowing, but did not have any narrow upright leaves. Roots had moderate hairiness, but no constriction or size reduction. This line is susceptible to Beet curly top virus (causes curly top) and Rhizoctonia solani (causes Rhizoctonia root rot). KEMS08 would be an excellent parental donor for CLS and Fusarium yellows resistance genes. | 1953785 | PI 683516 |

FC1740 has shown good resistance to beet curly top (Beet curly top virus), not different from the resistant control in 2 years of testing and although significantly less resistant than the resistant control in 2 other years, still more resistant than the susceptible control. It has shown excellent resistance to fusarium yellows (Fusarium oxysporum f. sp. betae and other Fusarium species), not significantly different from the resistant control in 2 years of testing.

The skin of F1043 is slightly darker than the skin of F1024 (Pl 658654) and most sugarbeet lines. In some cases, a light pink or rose color pigment is apparent, often on the upper portion of the root surface below the crown. The pigmentation affects only the root surface. The flesh immediately below any pigmented area is white, similar to F1024 and most other sugarbeet cultivars. A low frequency of plants with seed stalks (bolters) were observed in all selection-cycles but were never selected as mother roots to produce seed for the next generation, suggesting that complete elimination of bolters may be difficult. Hypocotyls of F1043 are red. The sugarbeet root maggot resistance of F1043 is equal to the resistance of F1024, a line with a high level of resistance that is not related to F1043.

Collins, CO, and for rhizomania and curly top reaction in Kimberly, ID. Overall agronomic performance of EL-A029709 was not significantly different from SP6822, the pollinator parent of the legacy hybrid USH20 (4,701 lbs sucrose/A versus 3,929.8, respectively). Stand establishment of EL-A029709 was not significantly different from the highest entry in the nursery (51.7 plants per plot versus 60.0 for EL-A024975). Cercospora leaf spot tolerance of EL-A029709 was not significantly different from the highly resistant check EL50/2 (PI 664912) (4.0 versus 3.0, respectively), and was not significantly different from the resistant Aphanomyces root rot check (3.4 versus 3.0, respectively), nor was it significantly different than the Rhizoctonia moderately resistant check variety (2.0 versus 1.8). EL-A029709 is susceptible to both rhizomania and curly top viruses. EL-A029709 was evaluated in three storage rots tests. A 4 cm slice of each root was taken, an agar block of hyphael inoculum was placed on the cut surface, and diameter and depth of rotted tissue was measured after 7 days. Pathogens were Botrytis sp. (isolate Bo09-2), Fusarium graminearum (F11-60), Penicillium sp. (Pe12-1), and Phoma sp. (Ph08-8). Comparison varieties were SP7322 and C869 (PI 628754), for which no significant differences between them were evident (except for depth of penetration by Phoma, which was 6.1 mm for C869 and 9.8 mm for SP6822). The depth and diameter of lesions caused by Phoma were significantly less on EL-A029709 relative to the checks (diameter 18.3 mm versus 22.1 for C869, depth 5.2 mm versus 6.1 for C869). Diameter, but not depth, was significantly different for EL-A029709 versus the checks for Fusarium (17.2 mm versus 24.1 for C869). No differences were observed for Botrytis or Penicillium on EL-A029709 versus the checks, although the diameter of rot caused by Botrytis at 3 days post-inoculation was significantly lower than the checks (14.0 mm versus 17.1 for C869). | 1927247 | PI 675153 |

No bolters were observed in F1042 during seven years of trials. The ratio of green to red hypocotyls was 74(G):26(R). In trials conducted at Fargo, ND between 2008 and 2014, the seven-year average sucrose concentration of F1042 was 141 g kg-1, compared to 148 g kg-1 for an adapted hybrid, ACH-999 (Crystal Beet Seed, Moorhead, MN), and 124 g kg-1 for the parental population, H-537. The seven-year average root yield of F1042 was 67% of the root yield of ACH-999. F1042 is susceptible to Rhizoctonia crown and root rot (Rhizoctonia solani) and Fusarium yellows (Fusarium oxysporum f. sp. betae), based upon single-year evaluations in the respective disease nurseries. F1042 has attracted the attention of some researchers because of its extreme susceptibility to Cercospora leaf spot (CLS: Cercospora beticola). Its extreme susceptibility to CLS may facilitate studies of the biology and inheritance of CLS resistance.

The EMS treated seed were planted and seedlings were observed for deviation from key morphological features of the control (PI663873) seedlings. KEMS-09 plant showed significant deviation from PI663873. KEMS-09 is homozygous for red hypocotyls (RR), has very long petiole, open canopy, small crown, puckered broad leaf, and normal tap root. KEMS-09 has been evaluated for agronomical important traits; such as curly top resistance (Ct), rhizomania resistance (Rz), sugar content, and postharvest storability. KEMS-09 showed exceptional resistance to rhizomania caused by Beet necrotic yellow vein virus (BNYVV) after being evaluated for three seasons in the USDA-ARS- Kimberly, Idaho disease nursery. This nursery is uniformly infested with BNYVV strains including the resistance breaking strain and routinely used for commercial variety testing. KEMS-09 showed better resistance to rhizomania than resistant cultivars which carry the Rz1Rz1 and Rz2Rz2 genes, therefore this line must be resistant to the BNYVV strains found in the nursery. Additionally, it showed significantly low level of fungal growth or root rots after 4 months of indoor postharvest storage at approximately 2oC. KEMS-09 is susceptible to Beet curly top virus (BCTV), Rhizoctonia root rot caused by Rhizoctonia solani, and highly susceptible to Cercospora leaf spot caused by Cercospora beticola. This line is a suitable parental line as a donor for rhizomania and storage rot resistance genes. | 1920335 | PI 672569 |

The EMS treated seed were planted and seedlings were observed for deviation from key morphological features of the control (PI663873) seedlings. KEMS-12 is a plant that showed significant deviation from PI 663873. KEMS-12 is homozygous for green hypocotyls (rr), has dark green glossy small leaf, extremely prostrate and small canopy, smooth long tap-root. Mature plants were vernalized and produced seed. KEMS-12 is self fertile and segregates for multigerm seed. KEMS-12 has been evaluated for agronomical important traits; such as curly top resistance (Ct), rhizomania resistance (Rz), sugar content, and postharvest storability. KEMS-12 showed high resistance to rhizomania caused by Beet necrotic yellow vein virus (BNYVV) when evaluated in the USDA-ARS- Kimberly, Idaho disease nursery for three seasons. This nursery is uniformly infested with BNYVV strains including the resistance breaking strain and routinely used for commercial variety testing. KEMS-12 showed no foliar symptoms and negligible root symptoms i.e. significantly less than the resistant check. Additionally, it showed superior storability with minimal fungal growth or root rots after 4 months of indoor postharvest storage at approximately 2oC. KEMS-12 has good resistance to powdery mildew caused by Erysiphe betae, and relatively acceptable sucrose content. This line is susceptible to Beet curly top virus (BCTV), Cercospora leaf spot caused by Cercospora beticola, and Rhizoctonia root rot caused by Rhizoctonia solani. We suggest that this line is a suitable parental line as a donor for rhizomania and storage resistance genes. | 1920336 | PI 672570 |

The F1, 20011046H2, was bulk increased (272 plants) to produce 20021036bb, which was bulk increased (96 plants) to produce 20051006. There were 57 half-sib families produced from seed of 20051006 (59 plants) and 20021036bb (43 plants) that were screened in an artificial epidemic of cercospora leaf spot (CLS) in East Lansing, MI. Remnant seed from the best performing 4 families was increased (396 plants) in the greenhouse to produce 20091029, which was bulk increased to 20111029 (62 plants) and 20141014 (147 plants). 20111029 was bulk increase to produce 20131006 (170 plants). This germplasm is a diploid multigerm sugarbeet population in normal cytoplasm, segregating for self-sterility (Sf:SsSs), multigermity (M:mm), and hypocotyl color (R:rr). FC305 has resistance to Fusarium yellows, moderate resistance to CLS, aphanomyces root rot, and beet curly top. This germplasm is segregating for resistance to rhizomania and contains both Rz1 and Rz2 genes for resistance. There was no resistance to root-rotting strains Rhizoctonia solani. This germplasm provides an alternate source of resistance to CLS and Fusarium yellows in a diverse genetic background to enrich the cultivated sugarbeet germplasm base. FC305 provides a source from which to select disease-resistant, multigerm pollinator parents. Because monogerm and O-type is within its parentage, it should be possible to select monogerm, O-type, and CMS maintainer lines from this germplasms as well. | 1918486 | PI 671963 |

EL50/2 is seed from this increase, designated EL-A021482, and has served as the resistant check in the Michigan Cercospora leaf spot nursery conducted in conjunction with the Beet Sugar Development Foundation since 2005. | 1898818 | PI 664912 |
| 64 | PI 664913 | 'EL58' | Beta vulgaris L. subsp. vulgaris | Michigan, United States | W6 | | Not Available | 2012 | DEVELOPED | PRE 2012 | | | | | Breeding material | A total of 17 roots were selected for survival from a SBCN field site in Bay City, MI in 2004 from germplasm provided by Dr. Bob Lewellen (USDA-ARS, Salinas, CA), and intercrossed in the greenhouse. Progeny were grown at the same site in 2006, and 23 mother roots were selected on the basis of root size and freedom from disease, and inter-pollinated in a 2006 greenhouse polycross with 301 mother roots from an 12 additional Salinas SBCN breeding lines [P507-303, CR511-7-302, R136, M1-4, 5927-202, 5927-4-302, M1-3, P207/8, N572-233, P507-306, M6-2, Y575-305] grown in the 2006 East Lansing breeding nursery, and two East Lansing breeding populations from the same nursery [95HS2/sel (30 roots), and 6869 x PI 546409 + PI 540625 (2 roots)], and seed was harvested in bulk from the 23 mother roots. From the resulting seed after planting under moderate nematode pressure, 56 roots were selected on the basis of plant vigor and size, and intercrossed in the 2007 greenhouse polycross with an additional 277 mother roots derived from the 2006 SBCN polycross and selected in East Lansing (non-SBCN), plus 362 mother roots derived from five East Lansing breeding populations [high sugar, smooth ?root elite lines (89 roots), EL55 (40 roots), 95HS2/sel (137 roots), 04B031 CMS/O-type group (7 roots), and a legacy breeding line labeled as possessing tolerance to Sclerotium rolfsii (43 roots)]. EL58 is the seed harvested from these 56 mother roots (designated EL-A022775). EL-A022775 yielded 50.0 lbs of roots/ plot in the 2011 Imperial Valley nematode trial as compared to resistant checks = 51.0 lbs/ plot, susceptible checks = 23.2 lbs/ plot. EL58 yielded 30.8 tons/ acre with 17.1% sucrose in 2009 (non-SBCN, Michigan). EL58, in 2009, was susceptible to Rhizoctonia (Ft. Collins, CO; 6.2 vs. 6.2 for the commercial susceptible check), resistant to Aphanomyces (Shakopee, MN; 4.0 vs. 4.5 for the resistant check), and susceptible to Cercospora leaf spot (Frankenmuth, MI; 4.3 vs. 5.5 for the susceptible check). | 1898819 | PI 664913 |

Briefly, EL59 was selected in Michigan from 15 breeding populations initially selected under severe sugar beet cyst nematode (SBCN) pressure in Brawley, CA and then under three cycles moderate SCBN pressure in Michigan, with inter-mating of selected mother roots. In 2007, five East Lansing breeding germplasms were also included in a large random mated population, with seed harvested from the maternal donors (e.g. from the 43 mother roots leading to EL59) and tested separately. EL59, tested as EL-A022784 in 2009, was susceptible to Rhizoctonia (Ft. Collins, CO; 5.5 vs. 6.2 for the commercial susceptible check), resistant to Aphanomyces (Shakopee, MN; 4.0 vs. 4.5 for the resistant check), and susceptible to Cercospora leaf spot (Frankenmuth, MI; 4.5 vs. 5.5 for the susceptible check). EL-A022784 yielded 26.4 tons/ acre with 16.7% sucrose content in a Michigan agronomic trial in 2009. In a 2010 Michigan nematode nursery selection plot, EL-A022784 yielded well as measured by plot weight. Seed of EL-A022784 was increased without selection and designated EL-A029768, which is being released as EL59. | 1898820 | PI 664914 |

From the 2008 SBCN selection nursery, a total of 88 mother roots were harvested from seed of the 2006 greenhouse polycross from M1-4 (4 roots), P507-303 (17 roots), N172 (12 roots), N112 (7 roots), CR511-7-302 (8 roots), R136 (12 roots), Y277 (14 roots), P207/8 (3 roots), and Y167 (11 roots) on the basis on lack of wilting and root size, and these mother roots were intercrossed with the population released as SR99, with seed harvested and combined from the 88 roots and designated EL-A024985. EL61 performed better than SR99 in the 2011 Imperial Valley CA SBCN nursery under severe SBCN pressure (52.3 vs 41.3 lbs/ plot, respectively), however under moderate SBCN pressure in Michigan in 2010, SR99 out-yielded EL61 (77.5 vs 67.0 lbs/ plot, respectively). EL61 is susceptible to Cercospora leaf spot (2009 Frankenmuth, MI; 5.7 vs. 5.5 for the susceptible check). Intercrossing EL-A024985 in isolation and without selection resulted in EL61 (EL-A029769). | 1898822 | PI 664916 |

EL-A021749 was planted in a moderate pressure SBCN nursery in Michigan in 2008 and seven mother roots were selected on the basis of size, freedom from disease, and lack of wilting. Seed, designated EL-A024988, was harvested from these seven roots in the 2009 greenhouse after inter-pollination with a sibling population of EL58. EL62 was tested as EL-A024988 in the 2011 Imperial Valley CA SBCN nursery under severe SBCN pressure where it yielded 49.0 lbs/ plot (compared with the resistant check = 51.0 lbs/ plot, susceptible check = 23.2 lbs/ plot) and in the 2010 Michigan nematode selection nursery under moderate SBCN pressure where it showed the highest root weight yield in the test (77.8 lbs/ plot vs. 73.8 lbs/ plot for the resistant check).

These were derived from a 2007 greenhouse polycross of SBCN breeding lines related to EL58, and seed from these 257 mother roots was harvested in bulk as EL-A022776. Fifty mother roots from EL-A022776 were selected on the basis of root size and freedom from disease in a mild SBCN selection nursery in Michigan in 2009, and intercrossed with 50 roots of EL-A022801, a sibling breeding line of the lineage leading to SR99, for incorporation of smooth-root and high sugar. EL63 is the seed harvested from EL-A022776, and is designated EL-A027007. EL63 was tested as EL-A027007 in 2011 where it yield 4063.3 lbs recoverable white sugar per acre (RWSA) among entries a 2011 Michigan SBCN trial with moderate nematode pressure (mean = 3,136.1 RWSA, LSD 0.05 = 717.7).

Whereas EL63 derives from germplasm selected under severe nematode and rhizomania pressures, EL64 derives from seed harvested from 30 mother roots of 95HS2 (EL-A013506) from a 2006 field polycross block with traditional East Lansing breeding germplasm, and these mother roots were intercrossed within a large polycross of SBCN donor germplasm in the 2007 greenhouse and this seed was designated EL-A021725, a progenitor of SR99. Seed of EL-A021725 was planted in the East Lansing observation nursery and 22 mother roots were selected on the basis of size, shape, freedom from disease, and low water content as determined by near-infrared spectroscopy, and inter-pollinated in a large field polycross in 2008, again with traditional East Lansing breeding germplasm, and this seed was designated EL-A022801. Fifty mother roots of EL-A022801 were selected on the basis of root size and freedom from disease in a mild SBCN selection nursery in Michigan in 2009, and intercrossed with 50 roots of EL-A022776 (EL63), for incorporation of SBCN tolerance. EL64 is the seed harvested from EL-A022776, and is designated EL-A027010. In 2011, EL64 gave 4140.5 lbs recoverable white sugar per acre (RWSA) among entries a 2011 Michigan SBCN trial with moderate nematode pressure (mean = 3,136.1 RWSA, LSD 0.05 = 717.7) and was scored as moderately resistant in the Michigan Cercospora leaf spot nursery and susceptible in the Shakopee, MN Aphanomyces disease nursery. | 1898825 | PI 664919 |
| 71 | PI 664920 | EL65 | Beta vulgaris L. subsp. vulgaris | Michigan, United States | W6 | | | 2012 | DEVELOPED | PRE 2012 | | | | | Breeding material | EL65 was selected and combined solely for root yield potential. EL65 was constructed in a polycross and is seed harvested from 25 roots of EL58 that went one further selection under mild SBCN pressure in 2009 and allowed to intercross with 25 roots, selected in the same nursery, of EL55 from the 2007 polycross from which EL58 was extracted. In addition, mother roots from non-SBCN field evaluations were included in the 2010 polycross, including 30 roots of the immediate progenitor of EL58 (=EL-A021737), 21 roots of EL59, and two breeding germplasms that have selection for salt-tolerant germination in their histories (in an effort to improve seedling vigor). These two salt-tolerant germination breeding germplasms from SR80 crossed with a range of wild biennial selections with good germination in 150 mM NaCl within 96 hours after imbibition (16 roots), and one of those improved wild germplasms (PI 357361, tested as EL-A022199) with excellent root size and conformation in a 2009 field evaluation (29 roots). EL65 was tested as EL-A027017.

EL66 was constructed in a polycross and is seed harvested from 16 mother roots selected for freedom from disease and root size of population EL-A021743, which contributed a substantial lineage (~50%) of its genetic ancestry to EL58. The polycross included field selections of mother roots made from mild nematode pressure of 25 mother roots of EL65 and 25 mother roots of an EL55 polycross progeny (EL-A022773) as well as roots from an evaluation nursery of EL-A021737 (25 roots, an EL58 polycross progeny), EL-A022791 (31 roots, a CN927-202 polycross progeny), EL-A021746 (20 roots, M1-4 progeny), EL-A022776 (24 roots, parent of EL63 progeny), EL-A021749 (16 roots, a M1-3 polycross progeny and descendant of EL62), EL-A022278 (20 roots, an M6-2 polycross progeny), and EL-A023052 (15 roots, a SR80 salt tolerant germination progeny). EL66 was tested as EL-A027143 in 2011 where it yield 3,655.2 lbs recoverable white sugar per acre (RWSA) among entries a 2011 Michigan SBCN trial with moderate nematode pressure (mean = 3,136.1 RWSA, LSD 0.05 = 717.7).

Seed from EL-A013506 was planted in a 2006 selection nursery in East Lansing, MI, and 30 mother roots were selected on the basis of near-infrared spectroscopy as having lower water content than their siblings, and these mother roots were intercrossed in the 2007 greenhouse polycross along with SBCN germplasm and East Lansing breeding material (as described per EL58), with seed harvested from EL-A013506 siblings and this seed designated EL-A021725. From the 2008 SBCN selection nursery, 46 mother roots from EL-A021725 were selected on the basis on root size and lack of wilting, and these mother roots were intercrossed with the direct progenitors of EL58 in 2009, with seed harvested from EL-A021725 siblings and this seed was designated EL-A024983. SR99 was tested as EL-A024983 in the 2011 Michigan nematode nursery under moderate SBCN pressure where it yielded 3904.1 pounds of recoverable white sugar per acre (trial average = 3136.1, LSD (5%) = 717.7) and the 2011 Imperial Valley CA SBCN nursery under severe SBCN pressure where it yielded a total root weight of 41.3 lbs/ plot (compared with the resistant checks = 51.0 lbs/ plot, susceptible checks = 23.2 lbs/plot). SR99 is susceptible to Aphanomyces (Shakopee, MN; 6.7 vs. 4.5 for the resistant check), and moderately susceptible to Cercospora leaf spot (Frankenmuth, MI; 4.3 vs. 5.5 for the susceptible check). | 1898821 | PI 664922 |

Each of these was harvested from one of three 2008 greenhouse polycrosses involving SBCN tolerant germplasm from the USDA-ARS Salinas CA germplasm enhancement program with smooth-root materials from East Lansing, MI and selected for good performance in Michigan growing conditions. Salinas donor germplasm included that described in the recent East Lansing germplasm release EL58. East Lansing germplasm contributing to SR100 includes selections from polycrosses involving unreleased smooth-root germplasm 95HS2 and releases SR94, SR96, SR97, EL51, EL0204, accompanied by field selection for low water content roots via near-infrared spectroscopy using a portable instrument in 2007. SR100 was tested as EL-A027152 in 2011 where it yield 3731.2 lbs recoverable white sugar per acre (RWSA) among entries a 2011 Michigan SBCN trial with moderate nematode pressure (mean = 3,136.1 RWSA, LSD 0.05 = 717.7) and was scored as moderately resistant in the Cercospora leaf spot disease trial and moderately susceptible in the Shakopee Aphanomyces nursery. | 1898828 | PI 664923 |

| 76 | PI 663880 | CD07 | Beta vulgaris L. subsp. vulgaris | California, United States | W6 |  | | 2011 | DEVELOPED | PRE 2011 | | | | | Breeding material | CD07 segregates for a genetic trait that causes the seed stalks to terminate in a flower bud, thus leading to determinate stalk growth. The inheritance of this trait was not determined but appeared to be a fairly simply inherited and recessive. This trait did not appear to affect vegetative plant growth. Plants with the determinate trait grew nearly normally during early development for seed stalks. However, at some point the elongated stalks and lateral branches terminated in a flower or cluster of flowers. It is not known if this trait could be developed to improve uniformity of seed set and maturity and thus seed quality. In these early selections for determinate growth, there appeared to be some detrimental effects on both male and female fertility and density of seed set, but selfing was possible. CD07 was selected from CP07 and will have similar traits. It will be multigerm (MM), self-fertile (Sf), and segregate for genetic male sterility (aa), hypocotyl color (33% rr) resistance to powdery mildew (Erysiphe polygoni) from WB97, resistance to rhizomania (Rz1) (Beet necrotic yellow vein virus), etc. CD07 may be useful in the study of the biology and genetics of flowering. | 1888703 | PI 663880 |

This condition results in very compact flowering and seed production. Seed yield is very high with good quality. There appears to be no detrimental effects on male and female fertility and pollen production is good. It was not determined how this compact flowering trait is inherited. CN926-11-10-91 is partially resistant to SBCN (Heterodora schachtii) with resistance likely derived from Beta maritima. It is resistant to rhizomania (Rz1) (Beet necrotic yellow vein virus) and biennial (bb), self-fertile (Sf), green hypocotyl (100% rr), and multigerm (MM). It should be nearly homozygous and very uniform. The two S5 lines combined were selected based on field tests where they had high resistance to SBCN, bolting resistance, and high % sugar. It is estimated that CN926-11-10-91 has 2% B. maritima germplasm through C51 (PI 593694). The inheritance of resistance to SBCN has not been determined. CN926-11-10-91 may be of interest in research on the biology and physiology of flowering and seed production as well as combined disease resistance. | 1888709 | PI 663881 |

CN24Hs1 segregates for resistance to SBCN (Heterodera schachtii). Hs1pro-1 conditions near immunity to SBCN (Heterodera schachtii). However the transmission of Hs1pro-1 is not stable and unless reselected each generation is lost. CN24Hs1 provides an advanced germplasm source with adaption to the western USA for selecting and developing true (homozygous for Hs1pro-1) breeding lines of sugarbeet with near immunity to SBCN. Plants that carry the Hs1pro-1 factor or chromosome fragment often form detrimental galls and there remains a yield drag associated with this condition. | 1888705 | PI 663882 |

Unlike C869, CN69 continues to segregate for non-O-types and multigerm. CN69Hs1 offers the opportunity to select for monogerm (mm), O-type lines with near immunity to SBCN by fixing Hs1pro-1 in a homozygous condition. In addition to being a potential source of resistance to SBCN, CN69Hs1 segregates for resistance to rhizomania (Rz1) (Beet necrotic yellow vein virus) and curly top. 100% red (RR) hypocotyls. | 1888706 | PI 663883 |

CN65-9Hs1 also is or segregates for self fertility (Sf), monogermity (mm),hypocotyl color (68% rr), O-type, and resistance to rhizomania (Rz1) (Beet necrotic yellow vein virus). Because of Hs1pro-1, it has a proclivity to produce galls. Inbreeding and galling cause it to have low vigor and seed production is difficult. In field trials it has low vigor but grows well until galling and changes in leaf and canopy structure lead to weakened plants. In greenhouse tests, every plant is essentially immune to SBCN (Heterodera schachtii) as measured by cyst counts. CN65-9Hs1 may offer the opportunity to select an O-type, mm line homozygous for SBCN resistance for use in varietal development and research. There may be an advantage to using Hs1pro-1 on the female side of a hybrid cultivar if transmission efficiency is improved. CN65-9Hs1 is the maintainer for CN65-9Hs1CMS. | 1888707 | PI 663884 |

It however is not homozygous resistant to SBCN conditioned by Hs1pro-1. It also retains more multigermity and non-O-type than CN65-9Hs1 leading to some partial pollen fertility that must be rogued during seed increases. CN65-9Hs1CMS offers a start to develop the equivalent of CN65-9Hs1 that is homozygous for Hs1pro-1, mm, and O-type. 18% rr hypocotyls. | 1888708 | PI 663885 |

It was selected from the 7th backcross to sugarbeet from the donor parent, WB258 (Yu, MH. 2002. Registration of sugarbeet germplasm M1-3 resistant to root-knot nematode. Crop Sci. 42:1756-1757). The recurrent sugarbeet parents in the last 5 backcrosses were C37 and C78 for the final 2 backcrosses. M1-4 should have characteristics similar to C78 including segregation for resistance to rhizomania (Rz1) caused by Beet necrotic yellow vein virus, moderate resistance to curly top, virus yellow, powdery mildew, bolting, and Erwinia root rot. M1-4 will mostly be self-sterile, multigerm, and segregate for hypocotyl color (31% rr). This germplasm and its source of root knot nematode resistance should be useful in the development of sugarbeet or other types of beets where there is an occurrence of Meloidogyne spp. and subtropical climatic conditions. M1-4 has good agronomic performance. Experimental hybrids produced with M1-4 in comparison to RKN susceptible hybrids would quickly give an estimation of presence and damage caused by RKN under field conditions. | 1888690 | PI 663871 |

About 75% of its germplasm comes from Salinas developments such as C931. About 25% comes from very high % sugar accessions from Poland. Population C943 segregates for resistance to rhizomania (Rz1) caused by Beet necrotic yellow vein virus. It has significantly higher % sugar than C931. It should be a source for combined disease resistance in a high sugar background that can be used to generate selfed progenies for improved performance. It is being stored as C943. | 1888697 | PI 663872 |

It is estimated to be about 12% high sugar Polish germplasm in a Salinas base. As a population, it had significantly higher sugar content than most Salinas open-pollinated and random mating populations. C944 is multigerm and self fertile and segregates of genetic male sterility (aa) and hypocotyl color (32% rr). It was developed to provide a source for population improvement using selfed progeny families that have potential for multiple disease resistance and sugar productivity. | 1888698 | PI 663873 |

C849 is or segregates for monogerm (mm), O-type, hypocotyl color (3% rr), resistance to rhizomania (Rz1) (Beet necrotic yellow vein virus), self-fertility, and genetic male sterility. It should have genetic variability for resistance to curly top. Approximately 12% of the germplasm is from very high % sugar accessions from Poland; 12% from C931(PI 636340); 25% from C869; and 25% from C833-5. Selected S1 progeny lines had significantly higher % sugar under rhizomania conditions than C842 (PI 634217) and C833-5. The selected S1s segregated for reaction to curly top in BSDF test at Kimberly. Because the final increase was from bulked seed produced on both genetic male sterile (aa) and fertile (A_) plants, C849 plants could be from either selfing or sibbing. A cycle of recombination through the genetic male sterile segregates is needed to bring the population into equilibrium. Subsequently, this self-fertile, random mating population could be used for population improvement and/or inbred line development. | 1888695 | PI 663874 |

The components of C21BM, C26 and C27, had been improved with multiple cycles of mass selection for elimination of easy bolting (annuals), for sugarbeet agronomic traits including root and crown conformation, root yield, and % sugar, and for disease resistance. Resistance selection was for rhizomania (Beet necrotic yellow vein virus), virus yellow (Beet virus yellows and Beet chlorosis virus), powdery mildew (Erysiphe polygoni), and Erwinia carotovora betavasculorum. This selection continued for five more cycles with the final two for resistance to resistance breaking strain of rhizomania (RB-BNYVV). C21BM should have genetic variability from B. maritima in a form that is easy to evaluate in standard sugarbeet variety trials. C21BM performs competively in sugarbeet variety trials for sugar yield. It is a potential source of resistance genes to existing and newly eruptive diseases of sugarbeet. C21BM is 82% rr. | 1888691 | PI 663875 |

Three separate groups were selected for resistance to rhizomania (Beet necrotic yellow vein virus) and sugarbeet type agronomic traits to eliminate easy bolting, and improve crown and root conformation, root yield, % sugar, and resistance to diseases. The final selection from the field was for plant conformation and resistance to resistance breaking strains of BNYVV (RB-BNYVV). C23BM should have genetic variability from a wide base of sea beet in a form that is easy to evaluate in standard sugarbeet variety and screening trials. Except for spangling and very high soil tare, C23BM performs competively in sugarbeet variety trials to evaluate and search for useful traits. C23BM should offer a broad based representation of North Atlantic Beta maritima for the entry level search for new and useful traits of all kinds. C23BM is 19% rr. | 1888692 | PI 663876 |

Preliminary tests (by Dr. HY Liu) suggested that it may also be moderately resistance to the vector of BNYVV, Polymyxa betae. As a line, self-fertile (SfSf), red hypocotyl (100% RR), C890-3-41 shows moderate resistance to cercospora leaf spot (Cercospora beticola), powdery mildew (Erysiphe polygoni), curly top, virus yellows, and bolting. Its canopy is small, dark green, and compact. It appears to segregate for monogerm (M:mm) and O-type. It has an R allele for dark red hypocotyls with pigment often extending into the petioles. | 1888696 | PI 663877 |

It was developed at Salt Lake City by Owen in the 1940-1950s and has been in continuous use at Salinas until 2006. It is the maintainer of the annual male sterile tester, C500H0. It is an excellent O-type, green hypocotly (100% rr), annual inbred. It is highly uniform and should have only green hypocotyls. It is known to have resistance to Beet mosaic virus (Bm). The annual gene (BB) was most likely derived from early Munerati material. It is an easy (fast) bolting annual. In tests for bolting tendency with hard bolting annual C600, it had at least 3 factors acting in a dominant manner for easy bolting compared to C600. Its (index) hybrids also bolt easily. | 1888693 | PI 663878 |

This genetic stock is highly resistant to beet curly top caused by Beet curly top virus, Beet mild curly top virus, and Beet severe curly top virus which are transmitted by the beet leaf hopper (Circulifer tenellus). It performed better than the resistant check in two greenhouse experiments and same as the resistant check in one field screening in the curly top nursery in Kimberly, ID. KDH13 has light green, upright, narrow leaves, and small compact canopy. It is susceptible to powdery mildew caused by (Erysiphe polygoni). KDH13 can be an ideal curly top resistance donor parent in hybrids, backcrossing, and inheritance studies and other economically important traits. KDH13 is a monogerm, self- fertile, and resistant to bolting. The initial ovule culture work was carried-out under contract by a private company. KDH13 developed by the sugarbeet group of the NWISRL, Kimberly, Idaho. | 1887452 | PI 663862 |
| 92 | PI 663213 | CY77 | Beta vulgaris L. subsp. vulgaris | California, United States | W6 | | | 2011 | DEVELOPED | PRE 2011 | | | | | Breeding material | CY77 combines germplasm from sugarbeet and Beta maritima that had been repeatedly selected for resistance to virus yellows (Beet yellow virus, Beet western yellows virus, Beet chlorosis virus) and rhizomania (Beet necrotic yellow vein virus). Resistance to rhizomania is most likely conditioned by Rz1 but other resistance genes may occur from the B. maritima components. The attempt was to find new genetic variability for VY in B. maritima and transfer it to sugarbeet. CY77 has VY resistance/tolerance similar to CY91 and CY95, but it is undetermined if this resistance came from the B. maritima germplasm or from the partially resistant sugarbeet recurrent parents that had been selected in the virus yellows resistance breeding program. It is estimated that 6% of the germplasm of CY77 is from B. maritima. As an open-pollinated breeding line, CY77 has good sugar yield with intermediate sugar content. It performs like a vigorous open-pollinated line in field trials without obvious B. maritima characteristics. | 1886698 | PI 663213 |

It segregates for resistance to rhizomania (Rz1) caused by Beet necrotic yellow vein virus. As an open-pollinated line it has high sugar yield and dark green canopy that does not yellow when stressed with nutrient deficiencies (Mn, Mg, Fe, ?) in field tests at Salinas. CY91 should be useful as an advanced source of combined resistance to VY, rhizomania, powdery mildew (quantitative), downy mildew, Erwinia, and other diseases prevalent in the fields in California. CY91 has moderately low resistance to curly top. | 1886699 | PI 663214 |
| 94 | PI 663215 | CY95 | Beta vulgaris L. subsp. vulgaris | California, United States | W6 | | | 2011 | DEVELOPED | PRE 2011 | | | | | Breeding material | CY95 is a broadly based population that recombines into one population 40 years of breeding efforts at Salinas, CA. The base germplasm is from both Beta vulgaris and Beta maritima (approximately 3% with annuals and wild beet traits largely selected against). The B. maritima is from a wide base of accessions. Sugarbeet germplasm traces to the traditional curly top resistant lines developed prior to 1960 and more recent European and non curly top resistant USA germplasm. During the 40 years of breeding at Salinas, host-plant resistances for virus yellows (Beet yellows virus, Beet western yellows virus, Beet chlorosis virus), powdery mildew (Erysiphe polygoni), Erwinia root rot (Erwinia carotovora betavasculorum), rhizomania (Beet necrotic yellow vein virus), cyst nematode (Heterodera schachtii), downy mildew (Peronospora betae) etc were targeted. Population improvement was run for high productivity using both mass selection and progeny testing. In the last step, full-sib families with high sugar content and yield from 17 lines were recombined. Some traits, eg, nematode resistance will be in low frequency; whereas Rz1 and Pm have moderated to high frequency. As a line, CY95 has robust growth and productivity. | 1886700 | PI 663215 |

EL56 is the first known sugar beet germplasm specifically selected for high germination in saline solutions. EL56 is a direct descendant of the Plant Introduction Accession Ames 3051, which was selected for germination in 150 mM NaCl through two cycles of selection and seed increase. EL56 was developed at the Sugarbeet and Bean Research Unit in East Lansing, Michigan. EL56 is expected to be used in developing pollinators for hybrids adapted to saline soil growing regions of the world, as well as assisting in land reclamation of such soils for remediation prior to growing salt sensitive crops. EL56 is diploid, self-sterile, multigerm, and biennial. | 1886696 | PI 663211 |

EL57 is being released as a source population from which to extract inbreds for use in making hybrids and as a vehicle for deducing the genetic basis of traits by selfing selected mother roots and examining segregation among their progeny. Traits expected to be segregating in the population include Aphanomyces seedling disease and Cercospora leaf spot resistances contributed by sugarbeet germplasms SP7622 (aka SP6822, 20% of original pollinators), USH20 (8% of original pollinators), and SP85303 (PI 590770, 6% of original pollinators), Rhizoctonia resistance derived from EL51 (PI 598074, 13% of original pollinators), curly top and rhizomania resistance selections from C931 (PI 636340) and EL0204 (PI 655951) (5% of original pollinators), a series of Aphanomyces resistant or salt-tolerant germination breeding lines and selections (derived from PI 165485, PI 271439, PI 518160, PI 546409, PI 562591, PI 562599, and PI 562601) (20% of original pollinators in total), a series of 17 nematode resistant breeding lines from the Salinas, CA USDA-ARS breeding program (13% of original pollinators), and a mixture of released and unreleased breeding lines derived from high sucrose, smooth-root selections (23% of original pollinators). Seed from hybrids of these materials crossed with male sterile, self-fertile C869 and derivative breeding lines was sown in the 2006 Rhizoctonia seedling and crown and root rot nursery, Cercospora leaf spot nursery, or the Michigan State University campus evaluation nursery, and 660 mother roots (four to six roots per entry) were harvested and selected on the basis of size, shape, freedom from disease, vernalized at 4o C for eight months, transplanted to a field seed increase plot, and allowed to randomly inter-pollinate. Seed was harvested in bulk from this group, and forms EL57. | 1886695 | PI 663212 |

SR98/2 is an intermediate stage of development and is expected to segregate for these and other traits, however a majority of individuals are expected to be highly resistant to seedling and crown and root rot diseases, or both. SR98/2 is diploid, self-sterile, multigerm, and biennial, and is expected to perform in a similar manner as SR98 (PI 655951) with respect to unselected traits. | 1848049 | PI 659754 |

The roots are larger and longer than those of F1016, its sugarbeet root maggot (Tetanops myopaeformis R der) resistant parent, and F1024 plants are generally larger and more vigorous than those of F1016. The root maggot resistance of F1024 is equal to or slightly better than that of F1016. Very little root maggot feeding is observed on F1024, even at lower depths where maggot damage is often the most prevalent on susceptible genotypes. F1024 has moderate resistance to Cercospora leaf spot (Cercospora beticola), a foliar disease of world-wide importance. Testcrosses with susceptible female lines had approximately one percent less sugar, higher root and recoverable sugar yields, and substantially less root maggot damage than otherwise adapted root maggot susceptible hybrids, when evaluated with no insecticide at sites with root maggot present. | 1831238 | PI 658654 |

SR98 appears to be useful as an additional source of Fusarium resistance. SR98 is an intermediate stage of development and is expected to segregate for these and other traits, however a majority of individuals are expected to be resistant to seedling or crown and root rot diseases, or both. SR98 is diploid, self-sterile, multigerm, and biennial. In the 2008 seedling Rhizoctonia nursery in East Lansing, SR98 had a mean stand count in July of 25.7 plants (std. dev = 3.5, n= 7 plots), relative to the resistant EL51 (mean = 21.0, std. dev. = 5.2, n = 4) and the susceptible SP7322 (mean = 2.5, std. dev. = 0.6, n = 4). Pre-inoculation stand counts taken June 29, 2008 for these three germplasms was 36.6 plants per plot (std. dev. = 7.4) with no significant difference between germplasms at this stage. In the 2007 Ft. Collins, CO Rhizoctonia crown and root rot nursery, SR98 had a Disease Index (DI; 0 = no disease, 7 = dead) of 1.7, relative to the highly resistant, resistant, and susceptible checks of 1.5, 2.8, and 3.5, respectively. Agronomic performance of SR98 has been reasonable in trials at the Saginaw Valley Bean and Beet Farm in Saginaw, MI. In 2008, 30-day emergence was 130.8% of eight commercial checks, yield was 85.3% of the same checks (19.6 T/A vs. 23.0 T/A), percent sucrose fresh weight was 90.7% of checks (16.8 vs. 18.6%), and percent dry matter was 88.8% of checks (21.2% vs. 23.9%). Sucrose percent expressed as a fraction of dry matter was 101.9% of checks (79.4% vs. 77.9%; range of commercial values = 75.0 to 80.3). | 1795198 | PI 655951 |

From over 4,000 legacy seedlots produced between 1961 and 1989 stored in ambient (high humidity) conditions, only 523 emerged under field conditions at the Saginaw Valley Bean and Beet Farm in Saginaw, MI in 2000. Only 71 of these stored seedlots gave commercially adequate stands (ca. 50% of planted seed), however each of these good seedlots was produced after 1988. Roots from the 12 oldest seedlots (i.e. those stored the longest) were collected as mother roots, and seed was produced. Using an accelerated seed aging protocol, this seed demonstrated slightly improved seed longevity. The majority of this germplasm is derived from remnant seed generated during development of seed parents in the germplasm conversion to hybrid seed production conducted by George Hogaboam (USDA-ARS, deceased). Thus, this material is also expected to be useful for developing cytoplasmic male sterility (CMS) parents for hybrid seed production. Reasonable to high levels of Aphanomyces blackleg and Cercospora leaf spot resistances is present in this material, as is customary of traditional East Lansing ARS germplasm. | 1789738 | PI 655304 |

In particular, EL-X2 is a sugar beet counterpart to releases EL-X1, EL-X3, and EL-X4 that were developed simultaneously with EL-X2 to examine introgression of Aphanomyces resistance from wild germplasm. In the Betaseed Aphanomyces nursery, the average rating of two Aphanomyces tolerant and two susceptible standards was 2.0 and 7.0, respectively (LSD (0.05)=1.83, average of two late readings), the sugar beet parents SP6822 and 6869 had scores of 1.0 and 5.5, respectively, and EL-X2 scored 4.5. | 1789740 | PI 655306 |

The average rating of two Aphanomyces tolerant and two susceptible standards was 2.0 and 7.0, respectively (LSD(0.05)=1.83, average of two late readings), the sugar beet parents SP6822 and 6869 had scores of 1.0 and 5.5, respectively, and EL-X3 scored 4.0. The wild beet parent of EL-X3 is WB185 (PI 546409), collected near Plymouth, England. WB185 is diploid, biennial, prostrate, with reported resistance to Cercospora leaf spot and Polymyxa betae. It was used because its potential resistance to Aphanomyces diseases caused by Aphanomyces cochlioides was evident by having a disease score of 1.0 (resistant) (rating system of 0-9 scale with 0 showing no symptoms and 9 being dead) in the 1994 Beta germplasm evaluation. Susceptible sugar beet 6869 (a progenitor of C869, PI 628754) was used as the sugar beet parent, and as a donor of the self-fertility (Sf) and nuclear male sterility characters. This release is expected to be self-fertile and segregating for nuclear male sterility. Tested seed was harvested from the sugar beet parent. | 1789741 | PI 655307 |

| 119 | PI 654357 | EL54 | Beta vulgaris L. subsp. vulgaris | Michigan, United States | W6 | | | 2008 | DEVELOPED | PRE 2008 | | | | | Breeding material | EL54 was developed at the Sugarbeet and Bean Research Unit in East Lansing, Michigan by J.M. McGrath. EL54 is released in the interest of broadening the genetic base of sugar beet. The parent accession WB879 was initially identified as resistant by C. Rush (Amarillo, TX) in the Sugarbeet Germplasm Committee s coordinated field trials in 1994 and reported as one of four accessions with very high resistance to Aphanomyces as judged by the lack of discoloration of hypocotyls. The introgression of this resistance into a sugar beet idiotype adapted to the humid Eastern U.S. growing regions was the desired outcome. EL54 has shown excellent Aphanomyces resistance in field trials in Michigan, Minnesota, and North Dakota. EL54 is expected to be a source for development of parental lines for hybrid cultivars resistant to Aphanomyces seedling damping-off as well as to mature root rot caused by Aphanomyces cochlioides Drechs. EL54 has shown a high degree of male sterility, and may be useful as an alternative source for deployment of cytoplasmic male sterility (CMS) for hybrid seed production. However, specific CMS maintainer lines have not yet been identified, nor has the cytoplasmic mitochondrial genome of WB879 been investigated. EL54 was increased in a 0.04 hectare plot in Oregon and harvested in four fractions (designated with a separate WC number); monogerm-male sterile (EL-A021485, WC050864), monogerm-male fertile (EL-A021484, WC050862), multigerm-male sterile (EL-A021481; WC050191), and multigerm-male fertile (EL-A021483, WC050860). This seed showed contamination (ca. 6%) with an unknown red chard-like pollinator. | 1780856 | PI 654357 |

It has moderate resistance to powdery mildew (Erysiphe betae) and good nonbolting tendency. It is moderately susceptible to curly top (Beet curly top virus). CR11-6 is intermediate in its reaction to Aphanomyces. CR11-6 has average sucrose concentration and its experimental hybrids had sugar yield equal to the mean of four current commercial hybrids grown in California under both rhizomania and nonrhizomania conditions. Resistance to cercospora leaf spot was at least partially derived (12.5% germplasm) from sugarbeet accessions obtained from Rovigo, Italy in 1989 from so-called Munerati and Alba material. | 1750190 | PI 652888 |

In tests at Salinas, CA, Fort Collins, CO, East Lansing, MI, and Shakopee, MN, it showed the highest resistance to cercospora leaf spot (Cercospora beticola) of any line developed at Salinas. CR11-7 segregates for resistance to rhizomania (Rz1:rz1rz1) caused by Beet necrotic yellow vein virus and genetic male sterility (A:aa). It has green hypocotyls (rr), multigerm seed (MM), and is self-fertile (Sf). It is moderately susceptible to curly top (Beet curly top virus) and moderately resistant to powdery mildew (Erysiphe betae). CR11-7 has an intermediate reaction to Aphanomyces. As a line it has a small, flat, smooth margin leaves with an upright, dark green canopy. It has average sucrose concentration and low sugar yield. In the absence of cercospora leaf spot and rhizomania, its experimental hybrids had intermediate sugar yield.

It is moderately resistant to powdery mildew (Erysiphe betae) and moderately susceptible to curly top (Beet curly top virus). CR951-210 may be unique in combining resistance to cercospora leaf spot and nonbolting tendency with tolerance to virus yellows caused by combinations of Beet yellow virus and Beet chlorosis virus. Under diseased conditions it has good sugar concentration and high sugar yield combining ability. It should be adapted to the areas in California subject to Cercospora, rhizomania, curly top, virus yellows, and other diseases.

It segregates for resistance to rhizomania (Rz1) caused by Beet necrotic yellow vein virus. In tests at Salinas, CA, Fort Collins, CO, East Lansing, MI, and Shakopee, MN, it had moderate to good resistance to Cercospora beticola and intermediate reaction to Aphanomyces. It appeared to segregate at a low frequency for resistance to Rhizoctonia solani AG-2-2. CR933 segregates for resistance to root aphids (Pemphigus sp.). It is moderately resistant to powdery mildew (Erysiphe betae) and tolerant to virus yellows caused by Beet yellow virus and Beet chlorosis virus. In tests at Kimberly, ID it had intermediate reaction to curly top (Beet curly top virus). It has a dark green canopy with smooth leaf margins. As a line, CR933 has high sugar yield and intermediate to high sucrose concentration when grown under rhizomania and/or cercospora leaf spot conditions. Resistances to Cercospora, root aphids, and Rhizoctonia are likely from traditional USDA-Fort Collins and Great Western Sugar Company, Colorado germplasm that traces back to GW359 and GW674. It may or may not be different from the Cercospora resistance found in population CR11.

Segregates for hypocotyls color and genetic male sterilty. Appears to be resistant to Erwinia and moderately resistant to curly top and powdery mildew. Segregates for resistance to rhizomania. In tests at Salinas and Brawley, hybrids had moderate to high sucrose content and sugar yield combining ability. Over wintered stecklings from Oregon of 8930-19 were transplanted into a field isolation plot at Salinas. In the absence of an artificially extended photoperiod, stecklings of 8930-19 were very slow to bolt and some plants did not flower. During seed harvest, these non-flowering plants were saved, regrown in the greenhouse, and vernalized in a cold room for 140 days, then replanted into a greenhouse isolation chamber with a 24-hour photoperiod. Under these conditions, this nonbolting selection from line 8930-19 produced seed. | 1631881 | PI 628758 |

Segregates for resistance to rhizomania. A composite of nine Polish accessions were crossed to genetic-male-sterile plants from a progenitor of population C918 to ultimately produce pop. CZ25. From the F1 pop. hybrid between CZ25 and C78, individual S0 plants were selected for resistance to rhizomania and were selfed in bags to produce S1 progenies. These S1 progenies were evaluated at Salinas for components of sugar yield and resistance to bolting, rhizomania, and powdery mildew. On the basis of these tests, S1 progenies were selected, increased, and testcrossed. Line 9930-35 was selected. | 1631882 | PI 628759 |
