<p>A novel gene that identifies a male sterile cytoplasm of a plant such as a crucifer, and a process for preparing a hybrid plant by using the same. This gene is useful as a novel cms cytoplasm gene usable in producing hybrid seeds of a plant and also in discriminating rapidly a Kosena ( Raphanus sativus ) cms cytoplasm which is a novel cytoplasm exhibiting a character useful for breeding. It is possible to add cms to not only a crucifer but also any plant in general by introducing the obtained gene into a nuclear genome or directly into a mitochondrial genome.</p> |
