Technical Abstract: Corn oil from Corn Belt lines has a very narrow range for fatty acid composition. Historically, this narrow range resulted from using genetically uniform material to create the modern Corn Belt hybrids. Several novel introgressed corn lines have been developed. The lines are developed from Corn Belt genetic materials introgressed with genetic material from corn's wild relative Tripsacum dactyloides L., in order to increase sources of genetic variability for breeding. During development of the lines, selections were made as well, including high protein content, high oil content, high oleic acid content, high or low saturated oil content, and/or starch having unique thermal characteristics. These lines can be used as breeding lines in a commercial corn breeding program to develop elite proprietary lines with higher levels of both protein and oil, increased oleic acid, higher levels of starch, oil, or protein, or starch with unique thermal properties. The elite lines would be parents in high-yielding commercial hybrids designed for feed or food use.
