Using the F2 mapping populationto make RAPD analysis,Pm12 was shown to be closely linked to the markerS1071900 at a genetic distance of 11.98±4.00cM. 2、Cross was made between Pm3b as resistant parent and Chancellor as susceptibleparent,and F1 plants from the cross were selfed to obtain F2 mapping population.

对 F2分离群体进行 RAPD 分析表明，该标记与 Pm12 基因之间的连锁距离为 11.98±4.00cM.2、以 Pm3b 为抗病亲本，Chancellor 为感病亲本，两者杂交的 F1代通过自交获得F2分离群体。
