摘　　要：在云南省水富县自然光温条件下,通过不同海拔分期播种试验,对籼型不育系蜀光612S、蜀光357S、泸光2号、2301S,及粳型核不育系N5088S、N7001S、N95076S、N94S的育性转换规律进行研究,结果表明,不论籼型还是粳型,育性转换在不同的环境条件下表现明显,其育性转换规律除了受品种特性主导外,温度对各不育系的育性转换起着决定性作用,而光照对其影响较小。To elucidate the fertility conversion of indica GMS,involving Shuguang 612S,Shuguang 357S,Luguang No.2,2301S,as well as Japonica GMS,involving N5088S,N7001S,N95076S,N94S,experiments were conducted at different sowing date and different altitude under the natural condition of Shuifu county,Yunnan province.The results indicated that the fertility conversion of male sterile lines was obvious in either indica or japonica rice,and the character of fertility conversion for sterile lines was mainly affected by the temperature and less by light.
