Their genetic behaviors were compared. The results indicate that Maxie A and Zhenshan 97A have same restoring maintaining relationship. Their progeny with Congguang41B and Miyang23 displays the segregation ratio of a pair of genes,while the progeny with Minghui63 shows the segregation law of two pairs of genes.The alleism test showed that their nuclear sterile genes are allelic. Maxie A and Zhenshan 97A belong to same genetic category. 细胞质雄性不育 遗传分析 水稻 cytoplasmic male sterility genetic analysis rice S511.103.2;Q943 国家自然科学基金(61672102) 1998-06-01 2021-04-01 6
