Abstract: Powdery mildew, caused by Erysiphe graminis f.sp.tritici, is one of the most serious wheat diseases throughout world. Growing resistant cultivars is the most economical and effective approach to control this disease. Molecular markers play an important role to locate genes with resistance to powdery mildew, and marker assisted selection has obtained some success. Now, 33 gene loci(Pm1-Pm31)for resistance to powdery mildew have been identified and located on different chromosomes, of which 28 alleles from 22 loci were successfully tagged or mapped. In this paper, the newest research of powdery mildew resistant genes was reviewed and applications of molecular assisted selection on breeding for disease resistance were discussed. At the same time, strategies and methods to solve questions were listed.
