USDA-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.

种子和粗粉蛋白含量高的高产成熟V组种质USDA-N5001的登记

USDA-N5001（注册号 GP-524，PI 702592）是一种常规早熟组 (MG) V 大豆 [ Glycine max (L.) Merr.] 种质，具有高产潜力和较高的种子和粗粉蛋白质含量。USDA-N5001是美国农业部农业研究局和北卡罗来纳州农业研究局于2023年1月联合发布的非转基因种质。USDA-N5001，实验名称N16-590，源自高产育种系杂交N08-145和高蛋白育种系Pro5-1。在 2019 年和 2020 年美国农业部统一大豆试验南部各州的 22 个环境中，USDA-N5001 的产率分别为“Ellis”、“AG55X”和“TN11-5140”这三张支票的 105%、98% 和 102%。在零水分的基础上，其蛋白质含量（425 g kg ^-1）显着更高（p  < 0.05) 高于检查结果 (399–402 g kg ⁻¹ )。USDA-N5001 的膳食蛋白质含量 (49.4%) 也显着高于 对照 (46.7%–46.9%) ( p < 0.05)。新版本的成熟期分别比Ellis和AG55X晚2天和1天，但比TN11-5140早5天。USDA-N5001 是北卡罗来纳州 USDA-ARS 开发的第一个高产、高种子和粗粉蛋白 MG V-Early（相对成熟度 5.3）品系。随着近期美国东南部 MG V 大豆产量的增加以及国家对高粉蛋白品系的关注，USDA-N5001 对美国东南部的大豆育种者和传统大豆种植者非常有用。
