By utilizing‘HL’type CMS line Congguang41A in combination with four restorers,the following generations:P 1、P 2、F 1（A×R）、BC 1（F 1×B）、BC 2（A×F 1）、F 2 were obtained. Results indicated that the male sterility of Congguang41A was gameophytic and was controlled by the interaction of a sterile cytoplasm with one pair of recessive nuclear genes. The comparison of restoring maintaining relationship and alleism tests between Congguang41A and Zhenshan 97A showed that their sterile nuclear genes were non allelic. The fertility restoration of ‘HL’ type CMS was governed by a single dominant nuclear gene. Miyang 23 possessed a pair of strong restoring genes,while Zhenshan 97 had a pair of partial restoring genes. 细胞质雄性不育 遗传 水稻 cytoplasmic male sterility genetic analysis rice S511.03 国家自然科学基金(61672102) 1999-04-01 2021-04-01 4
