FERTILITY RESTORER GENE FOR POLIMA CYTOPLASMIC MALE STERILITY

摘要

The present invention provides a restorer (Rf) gene for the "Polima" cytoplasmic male sterility in Brassica campestris (synonymus Brassica rapa) plants, and to a method of producing restorer lines in Brassica campestris. The invention further reveals that the restoration of "Polima" CMS in B. campestris is controlled by a single dominant gene. The identification of restorer of "Polima" CMS is potentially useful for the development of hybrid varieties in B. campestris.
