Abstract: The use of resistant cultivars is an effective, economical, and environmentally safe approach that eliminates the use of fungicides and reduces production losses due to powdery mildew caused by Blumeria graminis f. sp. tritici (syn. Erysiphe graminis f. sp. tritici). So far, 55 genes/alleles for resistance to powdery mildew at 39 loci have been identified and located on 16 different chromosomes,of which 30 resistance genes/alleles have been tagged by different molecular marker systems. Several quantitative trait loci (QTLs) for adult plant resistance to powdery mildew have been associated with molecular markers. The detailed information on chromosomal location,the sources, available molecular markers and cloning of these genes has been reviewed. The fresh researches, existed problem and the resolvent in marker-assisted selection using these genes are also discussed.
