Abstract: An inbred maize line, designated PH09B, the plants and seeds of inbred maize line PH09B, methods for producing a maize plant produced by crossing the inbred line PH09B with itself or with another maize plant, and hybrid maize seeds and plants produced by crossing the inbred line PH09B with another maize line or plant.

Abstract: According to the invention, there is provided an inbred corn plant designated 17DHD12. This invention thus relates to the plants, seeds and tissue cultures of the inbred corn plant 17DHD12, and to methods for producing a corn plant produced by crossing the inbred plant 17DHD12 with itself or with another corn plant, such as another inbred. This invention further relates to corn seeds and plants produced by crossing the inbred plant 17DHD12 with another corn plant, such as another inbred, and to crosses with related species. This invention further relates to the inbred and hybrid genetic complements of the inbred corn plant 17DHD12, and also to the RFLP and genetic isozyme typing profiles of inbred corn plant 17DHD12.

Abstract: A synthetic hybrid corn plant having the designation LP56.1, produced by crossing two proprietary Pfister Hybrid Corn Company maize synthetics, LP44.1A-Ht/wx Reid and LP43.2B-Lancaster. LP56.1 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. LP56.1 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 synthetic hybrid plants and seeds of LP56.1, i.e., the synthetic hybrid produced by crossing the two aforementioned parental synthetics and the seed thereof, including advanced generation seed, variants, mutants, and modifications of LP56.1.
