Abstract

Abstract:

Powdery mildew (PM) significantly and negatively affects the yield and quality of muskmelon (Cucumis melo L.var.reticulatus Naud.). Using the resistance genes of melon for breeding is the most economical and environmentally safe way to control powdery mildew disease. Through comparative genome analyses between the PM resistant varieties (PI414723,MR1), the reticulatus cultivars (Dulce,Harukei) and AY (the annonated melon genome),combined with the reported loci of disease resistance genes, we developed a new InDel marker named pmc2pi717 and successfully applied it to the resistance screening in the F₂ generation population. This study laid a foundation to pyramid multiple resistance genes into new cultivars in the future via marker assisted selection.
