本文报道了野败等8种不育胞质对杂种一代的株高、穗颈长、穗数、成穗率、实粒数、结实粒、千粒重和产量等性状表现负效应,抽穗期明显延迟;通过成株期伤口接种鉴定若干组合对白叶枯病的抗性表明,细胞质对白叶枯病的抗性不表现差异。作者认为,水稻不育胞质对杂种一代的表现型效应是与其不育性密切相关的遗传现象,同时。就如何化负效应为正优势,利用多基因的“保卫机制”选育高优势抗病的组合提出了初步设想。 In this paper, eight kinds of sterile cytoplasm such as wild loses were reported to have negative effects on plant height, ear length, number of spikes, percentage of spikelets, number of filled grains, grain weight, grain weight and grain yield of hybrids. The heading date was significantly delayed The resistance of several combinations to bacterial blight by inoculation of adult wounds showed that the resistance of cytoplasm to bacterial blight did not show any difference. The author believes that the phenotypic effect of CMS in hybrid rice is a genetic phenomenon closely related to its sterility. On the premise of how to turn negative effects into a positive advantage, the multi-gene “defense mechanism” has been used to breed high-quality disease-resistant combinations.
