Citation: Nelson, R.L., Johnson, E.O. 2011. Registration of Soybean Germplasm Line LG00-6313. Journal of Plant Registrations. 5:406-409. 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 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 LG00-6313 was developed and released by the USDA-Agricultural Research Service and the Illinois Agricultural Experiment Station, Urbana IL. LG00-6313 is an F6 line from the cross of PI 574480B x PI 574477. Both parents are Chinese cultivars that are not in the ancestry of any released germplasm or cultivar in the U.S. LG00-6313 is classified in early maturity group IV. In cooperative tests at 4 locations with private industry, 7 locations in the USDA Uniform Preliminary Group IV Test – Northern States, and 15 locations in the USDA Uniform Group IV Test – Northern States it yielded 110, 102, and 99% of the highest yielding check in each test. It is known to be susceptible to races 4 and 7 of Phytophthora root rot caused by Phythphthora sojae M. J. Kaufmann & J. W. 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.
