| 摘 要： | 运用简单重复序列(SSR)技术，采用分离群体分组分析法(BSA)进行了水稻农林8号m苯达松敏感致死基因的分子定位。结果表明，农林8号m苯达松敏感致死基因属于隐性单基因(bsl)，该基因位于水稻第3染色体上，并获得了与苯达松敏感致死基因连锁的2个SSR标记RM1350和RM3856，遗传距离分别为15．0cM和14．1cM。标记与基因间的排列顺序为：苯达松敏感致死基因—14．1 cM—RM3856-0．9 cM—RM1350。

| Abstract: | Mapping for bentazon susceptible lethality(BSL)gene in rice cultivar Nonglin 8m was carried out with simple sequence repeat(SSR)markers by bulked segregation analysis(BSA).As a result,the BSL gene was demonstrated as single recessive and located on chromosome 3.Linkage analysis indicated this BSL gene was linked to two SSR markers RM1350 and RM3856 with distances of 15.0 cM and 14.1 cM,respectively.The orientation of the gene and markers was determined as BSL gene-14.1cM-RM3856-0.9cM-RM1350. |
