In various embodiments, the present invention provides a method of extending the duration of pollen availability by planting a section of male parent seeds that includes alternating groups of male seeds adjacent to a section of female parent seeds in a field. The male seeds are planted and/or conditioned so that one group of male seeds produces plants that generally shed pollen at a different time than plants produced by the one or more other groups of male seeds. In some embodiments, the field may include multiple male and female sections and the male seed groups may alternate between sections so as to create a checkerboard pattern of male seed groups within the field. In some embodiments, the field may be planted with the aid of a positional data system.
