摘　　要：通过研究以温光敏不育小麦C4 9- 89S和绵阳 2 9号组配的正反交组合分离世代在不同播期中育性平均值的大小 ,探讨了细胞质对温光敏不育基因表达的影响。结果表明 :温光敏不育基因的表达不是通过胞质与细胞核互作产生的 ,但胞质对世代育性平均值的大小能产生作用 ,这种作用在早播时存在 ,随着播期的推迟 ,温光条件的改善 ,这种作用表现不明显。Fertility mean value of progenies from reciprocal crosses between C49-89S and Mianyang 29 were studied in several seeding times. The effect of cytoplasm on the expression of thermo-photo sensitive gene was probed into. The result showed that the expression of thermo-photo sensitive gene did not concern the interaction of cytoplasm and nuclear, but cytoplasm affected the mean of progenies from C49-89S, the effect was significant in early seeding time and insignificant in later seeding time. The probability of cytoplasm effect used in hybrid wheat was discussed.
