Abstract: 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® grain production system. P741 has shown excellent productivity in TC BLEND® 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.

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.

Abstract: A class of corn plants has been developed that are superior as pollinators in the TopCross.RTM. Grain Production System. The plants of this class are larger and more vigorous than many of the current TC Blend.RTM. pollinators. The seed that produces this new class of TC Blend.RTM. pollinators is produced at greater yields and is of greater vigor and quality than that of many current TC Blend.RTM. pollinators. Additionally, the means whereby the seed of this class of plants is produced enables the rapid generation of a wide range of maturities of TC Blend.RTM. pollinators. This greatly expands both the geographic range and the genetic breadth of the TopCross.RTM. grain production system.
