Registration of 'S17-2243C': A non-genetically modified maturity group IV soybean cultivar with high yield and elevated oil concentration

'S17-2243C' (Reg. no. CV-557, PI 700003) is a semi-determinate, maturity group IV (relative maturity 4.9), non-genetically modified (non-GM) soybean [Glycine max (L.) Merr.] cultivar developed and released by the University of Missouri-Fisher Delta Research, Extension, and Education Center. S17-2243C was developed to meet the growing demands for new non-GM soybean cultivars with high yield and elevated seed oil content. S17-2243C is resistant to stem canker and charcoal rot and has tolerance to salinity conditions. Seed of S17-2243C has averaged 232 g kg(-1) of oil concentration on a dry weight basis, which was significantly higher than all check cultivars in the 2020 USDA Uniform Soybean Tests, Southern States. S17-2243C was tested against high-yielding private and public soybean cultivars from 2018 to 2021 in 80 locations across 12 states, including Alabama, Arkansas, Illinois, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Ohio, South Carolina, Tennessee, and Virginia. With high yield potential, broad adaptability, early maturity, elevated seed oil content, and non-GM traits, S17-2243C is an excellent cultivar choice for soybean growers adopting alternative growing systems and benefiting from premium prices offered for non-GM soybean products.
