The conventional (non‐genetically modified) soybean [Glycine max (L.) Merr.] germplasm line R11‐7999 (Reg. no. GP‐436, PI 691646) was released by the Arkansas Agricultural Experiment Station in 2018 because of its high seed protein content and high yield potential. R11‐7999 is an F₄ selection from the cross between the Tennessee cultivar ‘5002T’ and the Arkansas advanced breeding line R00‐2097. Trial testing results of over 30 environments in Arkansas and other southern states shows that R11‐7999 is well adapted and exhibits high yield performance. R11‐7999 has a relative maturity of 5.7, determinate growth habit, purple flowers, tawny pubescence, and a tan pod wall at maturity. Seed of R11‐7999 has yellow cotyledons with dull yellow seed coat and brown and black hilum. It is resistant to stem canker and moderately resistant to frogeye leaf spot. R11‐7999 has a seed protein content of 439 g kg⁻¹ (dry weight), which combined with the seed oil (202 g kg⁻¹) content produces 50.7% protein in the meal fraction. The high yield and high protein content of R11‐7999 will make it a valuable cultivar for animal feed and protein isolate.
