Interpretive Summary: Soybean is a versatile oilseed crop providing vegetable protein and oil sources for livestock feed, edible oil, and industrial usages such as biofuel, representing 55% of the domestic market share. However, soybean yield potential can be significantly reduced by diseases and bad weather. In this research, a non-genetically modified soybean cultivar S16-7922C with high yield and broad disease resistance was developed. S16-7922C was tested in a total of 110 environments across 12 southern states during 2017-2020. Across all the locations and over years, S16-7922C averaged 4108.6 kg ha-1 which is 2.3% higher than the commercial checks. S16-7922 ranked in the top 26.8% in the Missouri and regional tests, top 21.2% in the United States Department of Agriculture uniform trials, top 53.6% in the state variety tests, and top 36.5% overall. S16-7922C is resistant to southern root-knot nematode and peanut root-knot nematode and moderately resistant to soybean cyst nematode races 2, 3, and 5 and reniform nematode. S16-7922C is also moderately resistant to charcoal rot, frogeye leaf spot, and stem canker. It is tolerant to salinity conditions and moderately tolerant to waterlogging stress. As a high-yielding soybean cultivar with broad adaptability, comprehensive disease resistance package, and high oil content, S16-7922C may be suitable for soybean growers interested in a maturity group IV non-genetically modified soybean variety.

Technical Abstract: The semi-determinate maturity group IV conventional (non-genetically modified) soybean [Glycine max (L.) Merr.] cultivar ‘S16-7922C’ was developed and released by the University of Missouri – Fisher Delta Research Center (UM-FDRC). S16-7922C was derived from the cross of ‘S11-16653’ x ‘S11-20124’ to recombine high-yielding alleles with multiple disease resistance alleles and desirable seed oil content. S16-7922C was initially tested in preliminary yield test at the UM-FDRC in 2017, and subsequently evaluated for yield performance, agronomic traits, and response to biotic and abiotic stressors in the advanced yield test, regional cooperative tests, USDA uniform soybean tests, and state variety tests in a total of 110 environments across 12 southern states during 2017-2020. Across all the locations and over years, S16-7922C averaged 4108.6 kg ha-1 which is 2.3% higher than the commercial checks (4018.4 kg ha-1). S16-7922 ranked top 26.8% in the Missouri and regional Crop tests, top 21.2% in the USDA uniform trials, top 53.6% in the state variety tests, and top 36.5% overall. S16-7922C is resistant to southern root-knot nematode and peanut root-knot nematode and moderately resistant to soybean cyst nematode races 2, 3, and 5 and reniform nematode. S16-7922C is also moderately resistant to charcoal rot, frogeye leaf spot, and stem canker and tolerant to salinity conditions and moderately tolerant to waterlogging stress. Plants of S16-7922C exhibit a relative maturity of 4.9 with an average of 81.9 cm in height, white flower, tawny pubescence, tan pods, and seed with black hilum. The seeds of S16-7922C contain 403 g kg-1 of protein, 226.g kg-1 of oil, 474 g kg-1 of meal protein on a dry weight basis. As a high-yielding soybean cultivar with broad adaptability, comprehensive disease resistance package, and high oil content, S16-7922C may be suitable for soybean growers interested in maturity group IV conventional soybean variety.
