Registration of high-oleic, low-linolenic and high meal protein conventional soybean germplasm USDA-N6007HOLL

Abstract

Oil accounts for about 50% of the value of soybean [Glycine max (L.) Merr.]. A changing marketplace demands soybean oil with reduced amounts of linoleic and linolenic acid to increase shelf-life and with increased amount of oleic acid to compete with heart-healthy oils. Meal accounts for the other half of the value of the crop. Higher protein quantity and quality in soybean meal increases its value as animal feed and human food. USDA-N6007HOLL is a conventional, maturity group VI soybean (Reg. no. GP-530, PI 706251) germplasm with white flower, gray pubescence, and brown pod wall jointly released by the USDA Agricultural Research Service and the North Carolina Agricultural Research Service in 2024. USDA-N6007HOLL is a high-yielding germplasm bred by backcrossing four fatty acid desaturase mutant alleles into ‘NC-Roy’. Yield, seed protein content, seed oil content, meal protein content, maturity data, plant height, lodging, and seed size of USDA-N6007HOLL were comparable to NC-Roy. These four fatty acid desaturase alleles result in oil with high-oleic (>80%) and low combined linoleic plus linolenic (<7%) acids. This oil profile meets the need of the world oil market for heart-healthy and shelf-stable oil competing well with olive and canola oil.
