Abstract
A synthetic hybrid corn plant having the designation P55, produced by crossing two proprietary DuPont TopCross International maize synthetics, LP41.1B-Lancaster and LP44.1A-Reid. P55 has the unique property of imparting high oil and high protein levels in the grain of certain normal and male sterile hybrids when used as a pollinator. P55 is characterized by excellent cold tolerant seedling vigor for rapid emergence in cold soils and excellent early-season adaptability to nick with early maize hybrids that condition fast dry-down and superior grain quality in the recipient female grain parent. This invention thus relates to the seeds, plants and plant parts of P55, to plants regenerated from tissue culture of the plants of P55, to a method of producing P55, and to a method for producing high oil grain using P55 as a pollinator.
