Abstract
A method is disclosed for creating and utilizing genic male-sterile maize for hybrid maize production. The method makes use of the Spm transposable element system and involves creation of a mutated male fertile allele, mutated by the presence of the Spm suppression receptor therein, expression of which is suppressed in the presence of the Spm suppressor. Methods are disclosed for transferring this system into any inbred line of interest for use in hybrid seed production.
