44	PI 643420	'GEMS-0067'	Zea mays L. subsp. mays	Missouri, United States	NC7	Not Available	2006	DEVELOPED					Cultivar	Vigorous line with pollen shed occurring approx. 4 d before B73, average plant height of 174 cm, upright leaf structure, yellow kernels and red cob. From the non-stiff stalk source H99ae x OH 43ae; of mixed heterotic derivation, composed of 50% non-stiff stalk and 50% stiff stalk. Subsequent crosses made with GEMS-0067 to both SS and NS testers have shown good yield in preliminary data over 2 years. GEMS-0067, having modifiers from GUAT209-S13 was compared to several public inbreds possessing the ae gene but without high amylose modifier genes. Starch was isolated from 2 bulk samples obtained from independent single-row plots derived from 2 GEMS-0067 S4 ears produced in 2004. Bulk samples from the converted lines H99ae, OH43ae, B89ae and B84ae grown in the same year were used for starch isolation. Analysis of amylose using the IA method confirmed the presence of modifiers in 2 samples obtained from GEMs-0067. Apparent amylose can be elevated as the result of long chained amylopectin; gel permeation chromatography (GPC) searates amylopectin from amylose and the intermediate components. Therefore, the GPC analysis method results in higher amylose values in comparison to the IA method ; GEMS-0067 displayed a relatively higher amylose value based on analysis of GPC amylose peaks. The resistant starch (RS) was also measured by using the Assoc. of Official Analytical Chemists (AOAC) method for total dietary fiber content for all samples. The RS content of GEMS-0067 starch samples was approximately two times higher than that of the converted public lines. The RS content of the starch samples was positively correlated with the amylose content of the starch, with a correlation coefficient (r) of 0.89. Thermal properties of the native high-amylose maize starch: water mixtures (3:1 ratio) were determined by Differential Scanning Calorimetery (DSC). All of the starch samples displayed similar onset gelatinization temperature (63.8-65.0?C). Broader gelatinization temperature ranges were observed for GEMS-0067 starches. The conclusion temperatures of these also varied from 104.8 to 106.7?C, and were substantially higher for GEMS-0067 starch than for the other starch samples (92.8-94.2?C. The results indicated that starch granules of GEMS-0067 samples were not completely gelatinized after cooking at boiling temperature; this is probably due to the increased amylose and intermediate component content.	1709493	PI 643420

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 yielded relatively well in topcrosses in the Midwest compared to other released GEM germplasm of a similar derivation. It flowers at approximately the same time as B73 in the southern US and shows common rust resistance. It has yellow kernels, semiflint to semident in texture.	1631417	PI 639040

Flowered 5 days later than B94 at Ames, IA in 1998, and 3 days later than B94 at Stoneville, MS in 1999. Donor parent, PI 503806, a tropical maize from Peru selected for resistance to leaf blade feeding damage caused by first generation European corn borer and leaf sheath and collar feeding damage caused by the second generation. Resistance for PI 503806 is not based on DIMBOA levels, a cyclic hydroxamic acid commonly associated with conventional leaf blade feeding resistance in maize. Breeding lines from the cross PI 503806 x B94 were advanced by backcrossing to B94 three generations. Throughout the breeding program, donor plants were selected by evaluating their resistance to European corn borer feeding on leaf blades, leaf sheaths, and collars of plants artificially infested with the insect. Only selected resistant plants were carried forward in the breeding effort. Third generation backcross seed were grown in Ames, IA in 1999 and plants were full sib-mated to obtain a seed increase for distribution. In addition to European corn borer resistance, also selected for superior yield compared to other experimental lines in the resistance breeding program. 160 second generation backcross parents from the breeding program were tested for yield. Three plants from each parent, including the parent of GEMS-0001, were selfed and crossed to a private non-stiff stalk tester, LH 185, and the hybrid seed was grown in a five location yield trial using U.S. Corn Belt locations. One parent hybrid of GEMS-0001 yielded well at 9756.1 kg/ha (155.6 bu/A) which was 95.3% of the highest yielding commercial check and 105.3% of the commercial check average. The other two parent hybrids of GEMS-0001 yielded 8941.0 kg/ha and 8727.8 kg/ha (142.6 and 139.2 bu/A).	1574895	PI 614142

Contains largely Reid germplasm, although lines selfed from it perform equally well when crossed to either heterotic pattern. Yield moderate. Ears medium, cobs red, and grain yellow. Plant and ear heights medium to medium tall. Stalk strength vairable due to susceptibility of some plants to common stalk rots. General health good. Most plants dark green. No data on root strength gathered but one line selfed from population is exceptional with respect to this characteristic.
