Registration of soybean germplasm line LG00-6313

Soybean [Glycine max (L.) Merr.] germplasm line LG00-6313 (Reg. No. GP-375, PI 660990) was developed and released by the USDA-ARS and the Illinois Agricultural Experiment Station, Urbana, IL. LG00-6313 is the progeny of an F5 plant from the cross PI 574480B × PI 574477. Both parents are Chinese cultivars that are not in the ancestry of any released germplasm or cultivar in the United States. LG00-6313 is classified as early maturity group IV. In cooperative tests at 4 locations with private industry, 7 locations in the USDA Uniform Soybean Tests-Northern States, Preliminary Test IV (2002), and 15 locations in the Uniform Test IV (2003), LG00-6313 yielded 110, 102, and 99% of the highest yielding check in each test. LG00-6313 is known to be susceptible to races 4 and 7 of Phytophthora sojae (Kaufmann & Gerdemann). LG00-6313 can be used as a parent for soybean breeding programs to provide new genetic diversity to improve the yield of U.S. cultivars.
