以来源于农垦５８ｓ的籼型光敏核不育系培矮６４ｓ和８９０２ｓ及其Ｆ１、Ｆ２群体为材料，通过不同光温和不同生态条件处理，研究了影响光敏核不育基因的育性不稳定性和育性可转换性的遗传机理，结果表明：光敏核不育系培矮６４ｓ和８９０２ｓ的光敏核不育主效基因等位。影响光敏核不育基因的育性不稳定性和育性可转换性可能均表现为微效基因的作用，且它们分别有独立的作用系统，环境温度对育性不稳定性和育性可转换性影响较大。
Genic male sterile lines Peiai 64s and 8902s derived from Nongken 58s and their F1 and F2 populations were used as materials. The fertility instability affecting the photosensitive genic male sterile gene was studied under different photoperiods and different ecological conditions And fertility transformability were studied. The results showed that the main genes of photosensitive genic male sterility of photosensitive genic male sterile lines Peiai 64s and 8902s were allelic. Both fertility instability and fertility transformability that affect photosensitive genic male sterility genes may all play the role of minor genes, and they have independent systems of action respectively. Ambient temperature can be transformed into fertility instability and fertility Sexual influence is bigger.
