15	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
16	PI 685801	'GEMS-0061'	Zea mays L. subsp. mays	Iowa, United States	NC7		2003	DEVELOPED	PRE 05/08/2003			Cultivar	A parent of GEMS-0061 is ARZM 16 026 which is PI 516027. It is an Argentine accession from the state of Mendoza that was identified as one of the LAMP (Latin American Maize Project) landrace collections performing in the top 5%.	1645902	PI 685801
17	PI 632413	'GEMS-0002'	Zea mays L. subsp. mays	Ohio, United States	NC7		2002	DEVELOPED	03/24/2002			Cultivar	Selected from the GEM FS8(A)S:S09 population. 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
18	PI 639039	'GEMS-0006'	Zea mays L. subsp. mays	North Carolina, United States	NC7		2002	DEVELOPED	2001	35.78900000, -78.67500000	146	Cultivar	Brazilian hybrid DK212T crossed to proprietary stiff stalk line from GEM "company 11". 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 has orange to yellow seeds and a semident to semiflint texture and shows common rust resistance.	1631414	PI 639039

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
