Abstract: A novel method of producing corn grain with enhanced quality traits including high oil content has been developed. Through pollination of male-sterile hybrid corn plants by nonisogenic corn plants possessing genes which control the expression of enhanced quality grain traits, grain is obtained possessing such traits much higher than would be expected for self- or cross-pollination. This method can be practiced by farmers using currently accepted farming practices to directly obtain high yields of high-oil corn grain, high-protein corn grain, and other valuable grain for animal feed and other products.
