0PI 675375NDEarlyGEM4Zea mays L. subsp. mays North Dakota, United StatesNC7EAR2015DEVELOPEDBreeding materialNDSUEarlyGEM4 is a unique maize synthetic variety created at NDSU for breeding programs developing short-season non-Stiff Stalk (SS) inbred lines. This new variety was developed by recombining 22 elite inbred lines giving top hybrid performance with industry testers across North Dakota environments. Tropical germplasm was brought from St. Croix to the central U.S. Corn Belt through the USDA-GEM program and then adapted to the northern U.S. through backcrossing with ND2000 elite short-season lines through the NDSUEarlyGEM program. New short-season inbred lines have been developed to increase the genetic diversity of U.S. northern hybrids. A heritability index included grain starch as priority when selecting lines for recombination. This variety has brought new genes for resistance to biotic and abiotic stresses.1927691PI 675375
1PI 675376NDEarlyGEM5Zea mays L. subsp. mays North Dakota, United StatesNC7EAR2015DEVELOPEDBreeding materialNDSUEarlyGEMS is a unique maize synthetic variety created at NDSU for breeding programs developing short-season non-Stiff Stalk (SS) inbred lines. This new variety was developed by recombining 26 elite inbred lines giving top hybrid performance with industry testers across North Dakota environments. Tropical germplasm was brought from Brazil to the central U.S. Corn Belt through the USDA-GEM program and then adapted to the northern U.S. through backcrossing with ND2000 elite short-season lines through the NDSUEarlyGEM program. New short-season inbred lines have been developed to increase the genetic diversity of U.S. northern hybrids. This variety has provided new lines with high combining ability effects for grain yield, fast dry down, drought tolerance, and disease resistance.1927692PI 675376
2PI 675381NDEarlyGEM22aZea mays L. subsp. mays North Dakota, United StatesNC7EAR2015DEVELOPEDBreeding materialNDSUEarlyGEM22a is a unique maize synthetic variety created at NDSU for breeding programs developing short-season non-Stiff Stalk (SS) inbred lines. This new variety was developed by recombining 21 earliest BC1 :S1 elite inbred lines giving top hybrid performance with industry testers across North Dakota environments. A heritability index included earliness as priority when selecting lines for recombination. Late temperate germplasm was brought from Chile to the central U.S. Corn Belt through the USDA-GEM program and then adapted to the northern U.S. through backcrossing with ND2000 elite short-season lines through the NDSUEarlyGEM program. This variety has brought new genes for high yield and protein quality.1927697PI 675381
3PI 675382NDEarlyGEM22bZea mays L. subsp. mays North Dakota, United StatesNC7EAR2015DEVELOPEDBreeding materialNDSUEarlyGEM22b is a unique maize synthetic variety created at NDSU for breeding programs developing short-season non-Stiff Stalk (SS) inbred lines. This new variety was developed by recombining 20 BC1 :S1 elite inbred lines giving top hybrid performance with industry testers across North Dakota environments. A heritability index included grain protein as priority when selecting lines for recombination. Late temperate germplasm was brought from Chile to the central U.S. Corn Belt through the USDA-GEM program and then adapted to the northern U.S.through backcrossing with ND2000 elite short-season lines through the NDSUEarlyGEM program. This variety has brought new genes for protein content and quality.1927698PI 675382
4PI 675383NDEarlyGEM26Zea mays L. subsp. mays North Dakota, United StatesNC7EAR2015DEVELOPEDBreeding materialNDSUEarlyGEM26 is a unique maize synthetic variety created at NDSU for breeding programs developing short-season non-Stiff Stalk (SS) inbred lines and unrelated lines. This new variety was developed by recombining 20 BC1 :S1 elite inbred lines giving top hybrid performance with industry testers across North Dakota environments. Germplasm was brought from tropical southern U.S. to the central US. Corn Belt through the GEM program and then adapted to the northern U.S. through backcrossing with ND2000 in the NDSUEarlyGEM program. New shortseason inbred lines have been developed to increase the genetic diversity of U.S. northern hybrids. This variety has brought new genes for grain yield and extractable starch.1927699PI 675383
