Interpretive Summary: First maturity group V public soybean germplasm USDA-N5001 developed in North Carolina demonstrated increased seed and meal protein, and competitive seed yield with check cultivars in this maturity group. With the recent increases in production of MG V soybeans in Southeastern U.S. and the national focus on higher meal protein lines, USDA-N5001 should be useful to soybean breeders and growers of conventional soybeans in the Southeastern U.S. This germplasm can also be important for sustainable plant protein initiatives to reduce excessive reliance on meat protein. USDA-N5001 is a conventional early maturity group (MG) V soybean germplasm with high yield potential, and elevated seed and meal protein contents. USDA-N5001 was jointly released as a non-GM germplasm by the U.S. Department of Agriculture-Agricultural Research Service and the North Carolina Agricultural Research Service in 2023. 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 zero moisture basis, its protein content (425 g kg-1) was significantly higher than the protein contents of the checks (399 to 402 g kg-1). The meal protein content (49.4%) of USDA-N5001 was again significantly higher than the checks (46.7 to 46.9%).

Technical Abstract: USDA-N5001 (Reg. No. _____, PI_____) 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-GM germplasm by the U.S. Department of Agriculture-Agricultural Research Service and the North Carolina Agricultural Research Service in 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 zero moisture basis, its protein content (425 g kg-1) was significantly higher (p<0.05) than those of the checks (399 to 402 g kg-1). The meal protein content of USDA-N5001 (49.4%) was also significantly (p<0.05) higher than the checks (46.7 to 46.9%). The new release matured 2 and 1 d later than Ellis and AG55X, respectively, but 5 d 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 Southeastern U.S. and the national focus on higher meal protein lines, USDA-N5001 should be highly useful to soybean breeders and growers of conventional soybeans.
