摘要： 通过大田分期播种，对现有主要光敏核不育水稻在杭州自然条件下的育性表达及其转换作了观察鉴定。结果表明，在杭州自然条件下，光敏核不育水稻的光温反应因遗传背景不同而异，育性转换的时间也不一致。温度在光敏核不育水稻育性表达与转换中起重要作用，对于籼型材料甚至占主导作用。

Abstract: The change of fertility in PGMSRs, including 6 indica and 5 japonica rices, was observed under natural conditions at Hangzhou (30°05′N, 119°56′E, 6.5m). It was shown that the response of PGMSR to photoperiod and temperature was different with their genetic background and that the fertility transfer date varied in the tested PGMSRs.Temperature played an important role in fertility transfer of PGMSRs, as to indica, its role seems much more important or dominant.
