Interpretive Summary: Oil accounts for about 50% of the value of soybeans. soybean oil with reduced amounts of linoleic and linolenic acid to increase shelf-life and increased amount of oleic acid to compete with heart healthy oils. USDA-N6007HOLL is a conventional, maturity group (MG) VI soybean germplasm. USDA-N6007HOLL is a high yielding germplasm with elevated levels of heart-healthy oleic acid and decreased levels of linoleic and linolenic acid that increase oil stability in storage. USDA-N6007HOLL was bred by backcrossing 4 well characterized fatty acid desaturases into NC-Roy. In addition to a desirable oil composition, USDA-N6007HOLL inherits the high yield and seed-protein composition of the NC-Roy recurrent parent.

Technical Abstract: Oil accounts for about 50% of the value of soybeans [Glycine max (L.) Merr.] crop. A changing marketplace demands soybean oil with reduced amounts of linoleic and linolenic acid to increase shelf-life and increased amount of oleic acid to compete with heart healthy oils. Meal accounts for the other half of the value of the crop. Higher meal protein quantity and quality in soybean meal increases its value as animal feed and human food. USDA-N6007HOLL is a conventional, maturity group (MG) VI soybean (Reg. No…, PI XX) 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 4 fatty acid desaturase mutant alleles into NC-Roy. USDA-N6007HOLL yield, seed protein content, seed oil content, meal protein content, maturity data, plant height, lodging, and seed size 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.
