Interpretive Summary: A critical component of increasing the yield of future U.S. soybean varieties is the incorporation of new genetic diversity. Less than 1% of the available genetic resources have been used to develop current varieties. To assist in introducing new genetic diversity that can increase future soybean yields, we have developed a new experimental line, LG00-3372, that is equivalent in yield to the best publicly developed varieties and has two Chinese varieties as parents. This line can be used by soybean breeders as a parent in variety development programs of both private industry and public institutions to introduce new genetic diversity and increase yield.
Technical Abstract: Soybean [Glycine max (L.) Merr.] germplasm line LG00-3372 was developed and released by the USDA-Agricultural Research Service and the Illinois Agricultural Experiment Station, Urbana IL. LG00-3372 is an F6 line from the cross of PI 561319A x PI 574477 and is classified in late maturity group III. PI 561319A is an introduction from China that is not in the ancestry of any released germplasm or cultivar in the U.S. PI 57447 is one of the parents of LG00-6313, a germplasm line also released by the USDA-Agricultural Research Service and the Illinois Agricultural Experiment Station, Urbana IL. In cooperative tests at 8 locations with private industry, 11 locations in the USDA Uniform Preliminary Group IIIB Test – Northern States, and 18 locations in the USDA Uniform Group III Test – Northern States, LG00-3372 yielded 104, 105, and 102% of the cultivar Macon. LG00-3372 is known to be susceptible to races 4 and 7 of Phytophthora sojae. LG00-3372 can be used as a parent for soybean breeding programs to provide new genetic diversity to improve the yield of U.S. cultivars.
