摘要
运用 RAPD技术 ,在番茄 To MV抗性基因 Tm2 nv的 F2 代群体中采用混合分组分析法 ( bulkedsegregant analysis,BSA)进行分子标记研究 ,找到了一个与 Tm2 nv基因连锁的分子标记 OPD2 0 170 0 ,其遗传距离为 7.0 67c M,L OD值为 16.
Randomly amplified polymorphic DNA (RAPD) was employed as a tool to detect molecular markers linked to the ToMV resistance gene Tm2 nv in tomato. A specific DNA band OPD20 1700 was proved to be linked to the gene Tm2 nv by bulked segregating analysis (BSA) with F 2 population. The genetic distance was measured as 7.067cM and LOD was 16.768.
