Abstract: The morphological characters of three kinds of reproductive mutants in rice were observed in the experiments. FM1 mutant could not enter into reproductive growth, and be kept in state of vegetative growth.FM2 mutant could not develop caropses, but could produce panicle branches with metamorphic leaves. FM3 mutant could not produce normal caropses, but could develop abnormal caropses with de generated pistil and stamens. It is known that the three kinds of mutant plants can not produce progenies by sexual reproduction. However, the dominate heterozygotes in the colony can produce both normal and mutant plants in next generation.
