提出利用自然日长鉴定粳稻光敏不育系的方法.应用AMMI(additive main effects and multiplicative interaction)模型,对8个水稻光敏不育系对日长和温度反应的遗传敏感性进行比较分析,将其育性敏感期日长分成6个梯度,温度分成11个梯度.结果表明:在杭州自然条件下种植参试的8个不育系均为光敏核不育系,具有以下特性,抽穗前10～20 d是育性转化敏感期,不育系的可育临界日长为13.0-13.8 h,育性的临界高温为25.0℃.临界低温为21.0℃.

We have developed an identification method for the PGMS (photo-sensitive genic male sterile) lines under the natural day length. A comparison of genetic sensibility of the eight rice genotypes to longday and temperature was performed with the AMMI (additive main effects and multiplicative interaction)model,in which the longday and temperature at sensitive stages of the fertility were divided into 6 and 11 gradients,respectively,the results showed that these eight lines grown under the natural condition in Hangzhou belong to PGMS type, with the following characteristics: 10-20 d before heading was the sensitive stage for the fertility transformation,3.0-13.8 h for critical day-length was 13.0-13.8 h,25 ℃ and 21 ℃ for the critical high temperature and critical low temperature of the fertility, respectively.
