Corn pollination with unrelated corn pollen

A method of preventing undesirable pollination in grain production, comprising:

• a. growing a grain parent corn plant that includes female components that receive pollen collected from a pollen parent corn plant;
• and
• b. intentionally applying said collected pollen to said grain parent corn plant on one or more days prior to said grain parent corn plant being subjected to undesirable pollen on said one or more days;
• wherein said grain parent corn plant is not male sterile at the time of said pollination and said female components are not isolated to prevent undesirable pollination, and further wherein said collected pollen is obtained from plants that are grown at a distance that does not enable natural cross pollination of said grain parent corn plants.

A method of corn production, comprising:

• a. growing a grain parent corn plant that includes both female and male components;
• b. intentionally applying pollen collected from a pollen parent plant on one or more days to said grain parent corn plant—when said male components are not shedding pollen on said one or more days;
• c. growing said grain parent corn plant to maturity;
• and
• d. harvesting the grain produced by said grain parent corn plant;
• wherein said male components are not male sterile at the time of said intentional pollination and said female components are not covered to prevent undesirable pollination, and further wherein said collected pollen is obtained from at least one of the following pollen parent plant sources:
• i) a pollen parent corn plant from an unrelated genetic background that has a different maturity period to the grain parent corn plant and
• ii) a pollen parent corn plant from an unrelated genetic background that does not have reproductive synchrony with the grain parent corn plant.
