摘　　要：对甘蓝型油菜核不育材料S1A进行遗传分析,以核不育两用系S1AB,S45AB,15AB,117AB互相杂交,结果表明,S1A核不育受隐性基因控制,S45A,15A,117A核不育基因等位,但S1A与S45A,15A,117A核不育基因不等位,S1A可能是1个新的隐性核不育突变体。Reciprocal crosses were made between the two-type genic sterile lines S1AB, S 45AB, 15AB and 117AB to study the inheritance of the new genic male sterile line S1A. The results showed that genic male sterility (GMS) in S1A was controlled by a recessive gene. While the GMS genes in S 45A, 15A and 117A were allelic, the GMS gene in S1A was non-allelic to them, suggesting that S1A may be a new recessive male sterile mutant in B. napus.
