Fecha de publicación: 25/05/1999 Fuente: WIPO "pollination" A synthetic hybrid corn plant having the designation P54, produced by crossing two proprietary DuPont TopCross International maize synthetics, LP39.1B-Lancaster and LP44.1A-Reid. P54 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. P54 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 P54, to plants regenerated from tissue culture of the plants or plant parts of P54, to a method of producing P54, and to a method for producing high oil grain using P54 as a pollinator.
