  • Patent number: 6248940
    Abstract: A synthetic hybrid corn plant having the designation P67, produced by crossing two proprietary Optimum Quality Grain, L.L.C. maize synthetics, P53.1A-Reid and P41.1B-Lancaster. P67 has the unique property of imparting high oil levels in the grain of certain normal and male sterile hybrids when used as a pollinator. P67 is characterized by excellent cold tolerant seedling vigor for rapid emergence in cold soils and excellent early-season adaptability facilitating nicking with early maize hybrids to condition fast dry-down and superior grain quality in the grain arising from the recipient female grain parent. This invention thus relates to the seeds, plants and plant parts of P67, to plants regenerated from tissue culture of the plants or plant parts of P67, to a method of producing P67, and to a method for producing grain using P67 as a pollinator.
