| 摘 要： | 本文对近两年来引进的几个水稻光敏核不育系的育性表现进行了观察分析,结果表明:两个粳型光敏核不育系双8—2S和农垦58S对温度不敏感,在9月4日以前抽穗的均表现为不育,花粉不育度≥99.8％;几个籼型光敏核不育系对温度都存在不同程度的敏感性,随温度的变化均不同程度表现育性波动;初步探讨了育性和温度、育性和播期的关系以及水稻光敏核不育系在生产上利用的可能性。

| Abstract: | The fertility of several rice nuclear-sterility lines of photor-sensitive has been observed for two years by the authers of this paper. The results showed as followos. two japonica rice nuclear-sterility lines of photosensitive such as Shuang 8-2S and Nongken 58S are not sensitive to temperature, and the degree of pollen sterility is over 99.8% as its earing before Sep. 4; other hsien rice ones are all sensitive to temperature in varing degrees and the sterility is waves along with the variance of temperature. Otherwise, the relationships between fertility and temperature, fertility and sowing time, and the possibility of the rice nuclear-sterility lines of photosensitive applied into production are discussed in this paper. |
