摘要
以农垦５８Ｓ，７００１Ｓ，５０４７Ｓ，Ｗ６１５４Ｓ，ＫＳ－９，培矮６４Ｓ，安农Ｓ－１和５４６０Ｓ等不同类型的水稻光温敏核不育系为材料，对单株育性的表现进行了观察，结果表明：除安农Ｓ－１外，其它７个不育系株内颖花间育性均存在显著差异，连续套袋自交对降低颖花间的育性差异效果不大；不育期间有少量自交结实，结实粒在穗上的分布是随机的，它们具有与相应不育系一致的光温敏核不育特性。
Different types of photoperiod-temperature sensitive genic male sterile lines,Nongken58S,7001S,5047S.Peiai64S,AnnongS-1and 5460S were used to observe the individual fertility,The results showed that except AnnongS-1,the highly significant difference of fertility among florets of a plant was found in other seven male sterile lines.The differenee of fertility among florets was not effectively reduced by continually bagging single plant.A few selfing seeds were found during sterile pe-riod,The selfing seeds distributed randomly on panicle and possessed photoperiod-temperature sensitive sterility like original male sterile lines after they were planted.
