Abstract:
1. A method for producing hybrid corn seed that enhances transgene trait purity and genotype purity comprising: (a) planting in a hybrid corn seed production field in pollinating proximity, seeds of a first parent corn plant and a second parent corn plant; (b) allowing said seeds to germinate and grow into plants, wherein said first parent corn plant comprises a first glyphosate tolerance transgene and is homozygous for said first glyphosate tolerance transgene and said second parent corn plant comprises a second glyphosate tolerance transgene and is homozygous for said second glyphosate tolerance transgene; (c) treating said plants in said seed production field with glyphosate, wherein said treatment consists of: (d) allowing the second corn parent plants to pollinate the first parent corn plants in said production field; (e) harvesting a hybrid corn seed produced on the first parent corn plant in said production field, wherein, the transgene trait purity and genotype purity of said hybrid seed produced by said hybrid seed production method is greater than in a hybrid seed production field not using said hybrid seed production method.
