Abstract
Methods for improving the efficiency and productivity of hybrid corn seed production are provided herein. Various methods to improve the transfer of pollen from male corn plants to female corn plants, and thus increase yield, are provided herein. Without being limiting, these methods include varying the height of male and female corn plants in a field, as well as varying the number, arrangement, and ratio of male-to-female rows in a field.
Claims37
A method of hybrid corn seed production, said method comprising:
- (a) fertilizing a plurality of female inbred corn plants with pollen from at least one male inbred corn plant to produce hybrid corn seeds, wherein the female inbred corn plants have an average height that is at least 2.5% lower than the average height of the at least one male inbred corn plant, and wherein the female inbred corn plants comprise a recombinant polynucleotide encoding an RNA molecule that suppresses expression of an endogenous GA3 oxidase gene;
- and
- (b) harvesting said hybrid corn seeds from one or more of the female inbred corn plants.
A method of hybrid corn seed production, said method comprising:
- (a) crossing at least one male inbred corn plant with a plurality of female inbred corn plants to produce hybrid corn seeds, wherein the plurality of female inbred corn plants have an average height that is at least 2.5% lower than the height or average height of the at least one male inbred corn plant, and wherein said female inbred corn plants comprise a recombinant polynucleotide encoding an RNA molecule that suppresses expression of an endogenous GA3 oxidase gene;
- and
- (b) harvesting said hybrid corn seeds from one or more of the female inbred corn plants.
A method of hybrid corn seed production, said method comprising:
- (a) planting at least one male inbred corn plant in proximity to a plurality of female inbred corn plants to produce hybrid corn seeds, wherein the female inbred corn plants have an average height that is at least 2.5% lower than the height or average height of the at least one male inbred corn plant, and wherein said female inbred corn plants comprise a recombinant polynucleotide encoding an RNA molecule that suppresses expression of an endogenous GA3 oxidase gene;
- and
- (b) harvesting said hybrid corn seeds from one or more of the female inbred corn plants.
