A synthetic hybrid corn line having the designation P741, produced by crossing the inbred Qx47 and the synthetic P732. P741 imparts a high oil level in the grain of certain male sterile hybrids when used as a pollinator. P741 is also gives higher test weight in grain than other pollinators of similar oil levels when used in the TOPCROSS&reg; grain production system. P741 has shown excellent productivity in TC BLEND&reg; seed blends of medium to late season adaptability. This invention thus relates to the seeds, plants and plant parts of P741 and its components, to plants regenerated from tissue culture of the plants of P741, to a method of producing P741, and to a method for producing high oil grain using P741 as a pollinator.

Corn hybrid P741

The present invention provides methods for preparing herbicide tolerant corn plants. Also provided are herbicide tolerant corn plants, as well as seeds and progeny derived from these plants.

Gene combinations for herbicide tolerance in corn

A hybrid corn line having the designation P723, produced by crossing the inbred Qx47 and the synthetic P39B. P723 imparts a high oil level in the grain of certain male sterile hybrids when used as a pollinator. P723 is characterized by good plant vigor, including seedling vigor in cold soil tests, and gives higher test weight when used in the TOPCROSS&reg; Grain Production System than other pollinators of similar oil levels. P723 has shown excellent productivity in TC BLEND&reg; seed products of early to medium season adaptability. This invention thus relates to the seeds, plants and plant parts of P723 and its components, to plants regenerated from tissue culture of the plants of P723, to a method of producing P723, and to a method for producing high oil grain using P723 as a pollinator.

Corn hybrid P723

A hybrid corn line having the designation P724, produced by crossing the inbred Q&times;47 with the progeny of the cross between proprietary inbred Z&times;23 and synthetic P22.1. P724 imparts a high oil level in the grain of certain male sterile hybrids when used as a pollinator. P724 is characterized by good plant vigor, including seedling vigor in cold soil tests, and gives higher test weight in TopCross&reg; Grain than other pollinators of similar oil levels. P724 has shown excellent productivity in TC Blend&reg; Seed Products of medium season adaptability. This invention thus relates to the seeds, plants and plant parts of P724 and its components, to plants regenerated from tissue culture of the plants of P724, to a method of producing P724, and to a method for producing high oil grain using P724 as a pollinator.

Corn hybrid P724

A hybrid corn line having the designation P725, produced by crossing two maize inbreds, Qx47 and Zx23. P725 imparts a high oil level in the grain of certain male sterile hybrids when used as a pollinator. P725 is characterized by excellent seedling vigor in cold soil tests and excellent productivity in TC BLEND&reg; Seed Corn Products of medium to late season adaptability. This invention thus relates to the seeds, plants and plant parts of P725 and its components, to plants regenerated from tissue culture of the plants of P725, to a method of producing P725, and to a method for producing high oil grain using P725 as a pollinator.
