M10-207102 (Reg. no. GP-446, PI 699000) is an early-maturing (relative maturity 0.0) conventional soybean [Glycine max (L.) Merr.] germplasm that was released by the Minnesota Agricultural Experiment Station in 2020. M10-207102 has an indeterminate growth habit, grey pubescence, purple flower color, and imperfect black hila. It combines Rps1c resistance to Phytophthora, high protein, high yield, and early maturity. The yield of M10-207102 was 93 and 96% of elite checks ‘ND Rolette’ and MN0095, respectively, in the Uniform Soybean Tests–Northern Region (NUST) during 2016–2019. The seed protein content of M10-207102 was 434 g kg–1, which was significantly higher than MN0095 (397 g kg–1) and ND Rolette (397 g kg–1). M10-207102 also had significantly higher meal protein content (49%) than the elite checks. Seed oil content of M10-207102 was about 2% lower than that of the check cultivars. M10-207102 is an excellent source of high protein that could be used to develop future cultivars high in both yield and protein.
