Abstract
The present invention relates to the field of producing hybrid seeds, and specifically relates to the application of certain cloned nuclear restorer genes that are active in reversing cytoplasmic male sterile systems. In particular, the present invention relates to: certain polynucleotide sequences that hybridize to nuclear restorer genes of plants, vectors, organisms, seeds, plant cells, and plants that comprise such polynucleotide sequences; a novel method for the production of hybrid seed that uses the aforementioned polynucleotide sequence; and a second novel method for the production of variant cytoplasmic male sterile factors.
