AbstractUSDA‐N5001 (Reg. no. GP‐524, PI 702592) is a conventional early maturity group (MG) V soybean [Glycine max (L.) Merr.] germplasm with high yield potential and elevated seed and meal protein contents. USDA‐N5001 was jointly released as a non–genetically modified germplasm by the USDA‐ARS and the North Carolina Agricultural Research Service in January 2023. USDA‐N5001, experimental name N16‐590, was derived from the hybridization of high‐yielding breeding line N08‐145 and high‐protein breeding line Pro5‐1. Across 22 environments of the 2019 and 2020 USDA Uniform Soybean Trials Southern States, USDA‐N5001 yielded 105%, 98%, and 102% of the three checks ‘Ellis’, ‘AG55X’, and ‘TN11‐5140’, respectively. On a zero‐moisture basis, its protein content (425 g kg−1) was significantly higher (p < 0.05) than those of the checks (399–402 g kg−1). The meal protein content of USDA‐N5001 (49.4%) was also significantly higher (p < 0.05) than the checks (46.7%–46.9%). The new release matured 2 days and 1 day later than Ellis and AG55X, respectively, but 5 days earlier than TN11‐5140. USDA‐N5001 is the first high‐yielding, high‐seed‐ and meal‐protein MG V‐Early (relative maturity 5.3) line developed by USDA‐ARS in North Carolina. With the recent increases in production of MG V soybeans in the southeastern United States and the national focus on higher‐meal protein lines, USDA‐N5001 should be highly useful to soybean breeders and growers of conventional soybeans in the southeastern United States.
