1. A method of cereal crop seed production, said method comprising:
a. growing a designated female cereal parent plant, said designated female cereal parent plant comprising both male and female components; having a pollination window and wherein said designated female cereal parent plant is exposed to undesirable pollen from an undesirable pollen source during said pollination window; and said pollination window has a first daily period wherein undesirable pollen is not shed and a second daily period wherein undesirable pollen is shed;
intentionally pollinating said designated female cereal parent plant on one or more occasions with designated male cereal pollen during said daily first period wherein pollen is not shed from said undesirable pollen source, when said male components of said designated female cereal parent plant are not releasing viable pollen and when plants of the same cereal species in proximity to said designated female cereal parent plant are not releasing pollen;
c. growing the designated female cereal plant to maturity; and
d. harvesting the seed produced by said designated female cereal parent plant; wherein the designated male cereal pollen is from a cereal plant genetically different from the designated female cereal parent plant; and wherein the designated female cereal parent plant is not covered to prevent pollination from the undesirable pollen.
