摘　　要：用马协Ａ和珍汕９７Ａ与１３个水稻品系杂交，对两者的遗传行为进行了比较．结果表明，马协Ａ和珍汕９７Ａ的恢保关系基本相同；它们与丛广４１Ｂ、密阳２３的杂交后代表现一对基因的分离规律，与明恢６３的杂交后代表现２对基因的遗传规律；等位性测验表明两者的核不育基因是等位的．马协Ａ和珍汕９７Ａ在遗传上属同一类型．s Maxie A and Zhenshan 97A were crossed with 13 rice varieties. 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.
