培育水稻新质源雄性不育系是保证杂交水稻高产、稳产和避免因细胞质单一引起的遗传脆弱性的重要手段。通过对分别具有野生稻、籼稻和粳稻细胞质的无花药不育材料Ｍ０１、Ｍ０２、Ｍ０３ 的研究发现：①水稻无花药雄性不育可由核质互作产生；②水稻无花药雄性不育特性可稳定遗传；③当水稻花药退化到仅剩余花丝时，其雌性生殖器官也发生相应的退化，从而导致雌性败育（ 结实率极低）；④水稻无花药不育系的恢复谱与现有所有水稻三系不育系的恢复谱不相同 Fostering a new CMS line for rice is an important means of ensuring high yield, stable yield and avoiding the genetic fragility caused by the single cytoplasm. Through the research on the sterile materials M01, M02 and M03 of the anther of cytoplasm containing wild rice, indica rice and japonica respectively, ①The male sterile of rice anthers can be produced by the interaction of nuclei; ②The male sterility of anthers of rice can be stabilized Genetic; ③ When the anther degenerated to only the remaining filaments, their female reproductive organs also degenerated accordingly, resulting in the abortion of female (seed setting rate is extremely low); ④ The restoring spectrum of the anther sterile line of rice is similar to all existing rice Three lines of male sterile restore spectrum is not the same
