Summary

The powdery mildew resistance gene Pm2 is effective in China. Bulked segregant analysis (BSA) was used to search for microsatellite markers linked to Pm2. Twenty-one microsatellite primer pairs located on chromosome 5DS were screened; three polymorphic loci Xcfd81-5DS, Xgwm190-5DS, and Xcfd18-5DS were linked to Pm2 using an F2 population from Chinese Spring × C114118 (with Pm2) consisting of 814 individuals. The genetic distances between Pm2 and the three markers were: 2.0cM, 34.2cM and 44.2cM, respectively. Microsatellite marker Xcfd81-5DS could be used in marker assisted selection for Pm2 provided any chosen Pm2 source also carries the relevant marker.
