A 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.
Sont décrits un nouveau gène identifiant un cytoplasme stérile mâle d'un végétal tel qu'une crucifère, et un procédé pour préparer un végétal hybride à l'aide de celui-ci. Ce gène est utile comme nouveau gène cytoplasmique cms permettant de produire des graines hybrides d'un végétal et également de distinguer rapidement un cytoplasme cms de Kosena (<u> Raphanus sativus </u>) qui est un nouveau cytoplasme présentant un caractère utile pour la sélection. Il est possible d'ajouter le cms non seulement à une crucifère mais également à tout végétal en général par l'introduction du gène obtenu dans un génome nucléaire ou bien directement dans un génome mitochondrial.
