PCT No. PCT/JP94/01625 Sec. 371 Date Jul. 12, 1995 Sec. 102(e) Date Jul. 12, 1995 PCT Filed Sep. 30, 1994 PCT Pub. No. WO95/09910 PCT Pub. Date Apr. 13, 1995A novel gene that can be used to identify male-sterile cytoplasm in plants, for example, of the Cruciferae family, and a method for producing hybrid plants using this gene are provided. This novel cms cytoplasmic gene is valuable in that it can be utilized in the production of hybrid plant seeds. This invention is also useful for rapidly identifying Kosena cms cytoplasm, a novel cytoplasm which exhibits characteristics valuable in plant breeding. In addition, this gene may possibly be used to confer cms onto a broad range of plant species, not limited to those of the Cruciferae family, by its introduction into nuclear or mitochondrial genomes.
