The release of soybean [ Glycine max (L.) Merr.] germplasm line DB0638‐70 (Reg. No. GP‐416, PI 686969) is part of an effort to broaden the genetic base of soybean germplasm in North American soybean breeding programs. DB0638‐70 was developed and released by the USDA–ARS, Stoneville, MS, as a conventional determinate maturity group IV high‐yielding germplasm line. It is an F 5 –derived line from the cross of USDA–ARS germplasm release DT98‐9102 × Japanese cultivar Gogaku (PI 594172 A). DB0638‐70 was tested for 3 yr in the United Soybean Board Southern Diversity Yield Trial Project over 14 trials across six locations, where DB0638‐70 was not significantly different from commercial high‐yielding checks ‘AG 4632’, ‘AG 4703’, and ‘AG 4907’ for yield in five of six locations. Over 19 trials in the USDA Uniform Soybean Tests, Southern States (Uniform Tests), DB0638‐70 yielded 95 and 92% of the commercial high‐yielding checks AG 4632 and ‘AG 4933’, respectively. DB0638‐70 seed averaged 390 g kg −1 protein and 231 g kg −1 oil in the Uniform Tests. DB0638‐70 is susceptible to southern stem canker, soybean cyst nematode, and reniform nematode. DB0638‐70 was shown to be resistant to frogeye leaf spot. DB0638‐70 can be used as a parent to improve yield and enhance genetic diversity.
