Genetic reduction of male fertility in plants

摘要

Genetic male sterile plants are provided in which complementing constructs result in suppression of a parental phenotype in the progeny. Methods to generate and maintain such plants and methods of use of said plants, are provided, including use of parental plants to produce sterile plants for hybrid seed production.

主权项

1. A method for increasing yield or maintaining yield stability in plants by: a) reducing male reproductive tissue development by expressing a transgene under the control of a male reproductive tissue preferred promoter; and b) increasing nutrient allocation to female reproductive tissue during concurrent male and female tissue development.
