| 1 | PI 639919 | Mp717 | Zea mays L. subsp. mays | Mississippi, United States | NC7 |  | | 2005 | DEVELOPED | | | | | | Breeding material | Developed and released as a source of resistance to Aspergillus flavus infection and aflatoxin accumulation. Developing ears were inoculated with an A. flavus spore suspension 7 to 14 d after silk emergence. Ears were harvested at maturity, and grain was analyzed for aflatoxin contamination. Flowers approximately 7d earlier than Mp313E and 14 d earlier than Mp715. Mp313E and Mp715 were also released as sources of resistance to A. flavus/aflatoxin. This release has yellow kernels and white cobs. Plants are approximately 1.6 m tall. | 1680961 | PI 639919 |

Genetic composition of the population FS8(A)S (PI 536619) is estimated to be approx. 50% BSSS related, 21% tropical, 18% southeastern U.S., and 11% diverse Corn Belt (with a high proportion of inbred C103A). Breeder's seed of GEMS-0002 was increased by controlled full-sib pollination of the S3 in the 2002 OSU nursery. Seed from over 100 ears was bulked for distribution. It has been released to GEM cooperators following the GEM protocol. Mid-silk date is approx. one week earlier than that of B73 in Ohio, and it produces moderate amounts of pollen. Plant height is quite moderate (ave=133.2 cm) and ear placement is slightly below mid-plant height (ave=55.8 cm). Cob color is white and ears generally display 12 kernel rows (average 12.5, range 10-16). Ear width is approx. 3.8 cm (range 3.5 to 4.4 cm). Ear length is approx. 13.2 cm (range 11 to 15 cm). Kernels are yellow to yellow-orange in color and are slightly dented to flinty and have a 100 kernel weight of 21.7 g. Grain protein composition is somewhat elevated (approx. 2 to 2.5 points above B73) and average density is 1.35 g/cc. Line has not been exposed to high levels of foliar or stalk-rotting diseases and definitive information concerning its susceptibility to pests and diseases is unknown. GEMS-0002 is intended as a breeding resource for the improvement and diversification of elite, non-'Lancaster Sure-Crop' related inbreds. Unique in that it has a relatively high proportion of tropical germplasm yet is able to impart earliness to hybrids. It has potential as a source of germplasm in breeding programs throughout much of the U.S. Corn Belt. Recommended that it be introduced into breeding programs by crossing with elite inbreds followed by modified pedigree selection. Using this method, it is anticipated the agronomic characteristics can still be improved since only one cycle of selection has been practiced. | 1641703 | PI 632413 |

Germplasms were developed by selfing and selecting variable F1s from tropical-source x US inbred crosses in North Carolina under standard nursery conditions, followed by a second selfing/selection season in Homestead, FL (F2S1), and a third selfing/selection season in a selection nursery in Raleigh (F2S2). All procedures were carried out using ear-to-row methods, except that F2 seeds planted in Homestead were bulked by pedigree. Germplasms were selected on the basis of resistance to a mixture of foliar diseases (Southern and Northern Leaf Blight, Anthracnose, Gray Leaf Spot), resistance to Fusarium ear rot, resistance to Anthracnose stalk rot, resistance to lodging , early flowering, synchrony of silk and pollen production, and reduced plant and ear height. This germplasm yields well in the southern US in topcrosses to non-stiff stalk testers compared to elite hybrid checks. It showed good per se resistance to Aspergillus ear rot and to aflatoxin accumulation. It produces yellow kernels, semiflint to semident in texture. | 1631408 | PI 639055 |

Plant 226 cm in height to tassel tip, 79 cm to base of top ear, top ear internode is 13 cm long, no tillers, single ear per stalk, and normal cytoplasm. Leaf color 5GY 4/4 (Munsell Color Charts for Plant Tissues), less than 30 degree angle from stalk, light sheath pubescence, no marginal waves, few longitudinal creases, 8 cm at widest point of ear node leaf, 85 cm ear node leaf, with 12 leaves per mature plant. Tassel has 9 lateral branches, 30-40 degree branch angle from central spike, penduncle length from top leaf to basal branches 11 cm, medium pollen shed, anther purple and glume green with purple stripe. Ear 13 cm long, 40 mm mid-point diameter, 74 grams, 16 distinct and straight kernel rows, green silk, husk light green when fresh and buff when dry, husk extension 8-10 cm beyond ear tip, husk leaf less than 8 cm, shank 8 cm long with 7 internodes, pendent at dry husk stage, slight taper, and average drying time (unhusked ear). Kernel 12 mm long, 8 mm wide, 4 mm thick, 30-60% rounds, colorless pericarp, aleurone homozygous and white, endosperm yellow, normal starch type endosperm, and 28 grams per 100 seeds. Cob 30 mm diameter at mid-point, strong, and red. Disease and insect resistance not tested. Most closely resembles LH119 for maturity, plant type, ear type, kernel type, and usage. In later progeny inbred releases, the developer writes: LH132 has been used as a replacement for B73 in many hybrid combinations. LH132 is a superior seed parent to B73 and greatly improved the production and quality of hybrid seed. LH132 also contributes a larger seed size which reduced the amount of discard that was common with B73. LH132 hybrids have lower ear placement than comparable B73 hybrids and have significantly improved stalk and root qualities. | 1157405 | PI 601004 |
