Interpretive Summary: Soybean is one of the most widely-used sources of protein for animal feed and are also used for human consumption. They provide high levels of amino acids and are a good source of energy, vitamins, and minerals for livestock feed. The protein content of soybeans grown in the United States has been decreasing as breeders push to increase yield. Additionally, modern North American soybean cultivars have very low genetic diversity. This is mainly due to the difficulty in developing high yielding lines from un-adapted exotic germplasm. G11-7013 has 50% exotic genetic diversity by pedigree, resistance to SCN and RKN, and high meal protein. Thus, this germplasm line has potential to be used by soybean breeders to develop new high yielding, nematode resistance, and high protein cultivars with beneficial genes from exotic germplasm.
Technical Abstract: G11-7013 (Reg. No. GP___, PI_____) is a conventional maturity group (MG) VII soybean line [Glycine max (L.) Merr.] containing 50% exotic genetic background by pedigree with high meal protein and resistance to soybean cyst nematode race 3 (Heterodera glycines), southern root-knot nematode (Meloidogyne incognita), and stem canker (Diaporthe aspalathi). G11-7013 was developed and released by the University of Georgia (UGA) Agricultural Experiment Stations. G11-7013 is an F5–derived plant selection from ‘Boggs’ × PI 221717. G11-7013 consistently yielded more than the elite MG VII parent ‘Boggs’ in UGA advanced yield trials. Across 25 environments in the United Soybean Board Diversity MG-VII (USBDIV-7) Tests, G11-7013 yielded 92.7-103.5% of the elite check mean over five years with an average of 98.4% of check means. G11-7013 has a protein content of 379 g kg-1, a meal protein value of 50.7%, and an oil content of 18.9 g kg-1. G11-7013 exceeds the desired protein levels with a diverse genetic background. With its high yield, high protein content, disease resistance package, and diverse genetic background, G11-7013 can be used as a parental stock in both public and private sectors to develop high yielding high protein soybean cultivars.
