一个与甘蓝显性雄性不育基因连锁的RFLP标记

Identification of a RFLP Marker Linked to a Donminent Male Sterile Gene in Cabba ge

运用RFLP技术 ,采用集群分析 (BSA)法进行了甘蓝显性雄性不育基因连锁的分子标记研究 ,结果表明 ,该显性不育基因与RFLP标记pBN11连锁 ,经两个回交群体检测 ,其遗传距离分别为 5 189和 1 787cM ,首次将该不育基因被定位于第 1和第

Bulked segregant analysis was used to identify RFLP ma rker linked to a dominant male sterile gene in cabbage(Brassica oleracea var .capitata).The dominant male sterile gene was found to be linked to RFLP mar ker pBN11.The genetic distance between the marker and the dominant male sterile gene is 5 189cM and 1 787cM in two backcross populations,respe ctively.The gene was located on chromosome 1 and 8.
