Commercial high-oil com hybrids have not been widely used by growers because their grain yield potential is generally lower than that of normal dent hybrids. The recent rediscovery of the xenia effect resulted in a return of high-oil com as a viable crop, marking the beginning of a new age in agricultural production. Interplanting high-oil males among male-sterile females in a ratio of as little as 7-8 % of the population resulted in increased oil content without affecting the grain yield of the hybrid. The grain parent (female) is the male-sterile version of an elite hybrid that may be in commercial production. The pollinator is a special line, normally with a high oil (and protein) content, that sheds pollen within the grain production field. The pollen shed from the pollinator plants contains special genes that cause the kernels to produce embryos much larger than average. Since the oil and and the majority of the essential amino acids and protein are in the germ, the oil (and thus the energy) level and protein quality of the grain produced by fertilization with these pollinators are enhanced. The pollinator plants contribute little to the overall grain yield, thus the average yield is not modified by their lower yielding ability. In the persent paper the brief history of high-oil corn and the present situation are reviewed.
