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.
Claims18
A 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 plurality of 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 plurality of female inbred corn plants comprise a mutant allele of an endogenous Brachytic2 (br2) locus that comprises a premature stop codon within a nucleic acid sequence encoding a Brachytic2 protein as compared to a nucleotide sequence encoding a wild-type Brachytic2 protein that comprises a sequence having at least 95% identity to SEQ ID NO:
- 132 or SEQ ID NO:
- 180;
- and
- (b) harvesting said hybrid corn seeds from one or more of the plurality of female inbred corn plants.
