对粳型光敏核不育系农垦５８Ｓ及其衍生的７个籼型光、温敏核不育系双列杂交组合Ｆ１和部分Ｆ２在长日高温和长日中温两种生态条件下的育性表现进行了研究。结果表明，光敏不育系农垦５８Ｓ、８９０２Ｓ和２８７７Ｓ、以及温敏不育系培矮６４Ｓ、８８０１Ｓ和２５５８Ｓ等６个不育系的不育主基因等位，温敏不育系Ｗ６１５４Ｓ和９２０２Ｓ的不育主基因等位，而前６个与后２个不育系的不育基因则非等位。不育主基因等位的Ｗ６１５４Ｓ和９２０２Ｓ杂交Ｆ２群体中不育株率１００％，而８９０２Ｓ、２８７７Ｓ、培矮６４Ｓ和２５５８Ｓ间杂交Ｆ２群体中有少量可育株出现。不育主基因等位的不育系间杂交Ｆ２群体中，可育株与不育株比例为２２５∶３１，表明双亲之间存在４对不育主基因的差异，控制Ｗ６１５４Ｓ和９２０２Ｓ不育性的２对主基因与控制８９０２Ｓ、２８７７Ｓ、培矮６４Ｓ和２５５８Ｓ不育性的２对主基因可能完全不等位。
Fertility of Japonica Type Photoperiod-Sensitive Genic Male Sterile Line Nongken 58S and Its Seven Indica Photo / Thermo Sensitive Genic Male Sterile Lines F1 and F2 in Two Long-term and Medium-temperature Conditions Performance has been studied. The results showed that the main male sterile lines Nongken 58S, 8902S and 2877S, and the thermo-sensitive genic male sterile lines Peiai 64S, 8801S and 2558S were the major sterile alleles of W6154S and 9202S The main male sterility alleles, but the first 6 sterile sterility genes and the latter two sterile lines were non-allelic. The infertile plants in the F2 population of the male sterile alleles W6154S and 9202S had 100% fertility, but a few fertile plants appeared in the F2 populations of the crosses 8902S, 2877S, Peiai 64S and 2558S. Among the F2 populations of the male sterile line alleles with sterile major alleles, the ratio of fertile plants to sterile plants was 225:31, indicating that there were 4 pairs of male sterile major genes in their parents, controlling W6154S and 9202S infertility The two pairs of major genes and two pairs of major genes controlling 8902S, 2877S, Pei’ai 64S and 2558S infertility may be completely out of position.
