Abstract: In order to establish molecular marker-aided selection system of the gene for disease resistance to powdery mildew on Cucumis melo L,with six generation population P1,P2,F1,F2,BCr and BCs from a cross between a resistant variety 1A151 and a susceptible variety Hengjing R. R. S. as materials, genetics and molecular marker of the disease resistance gene was studied using wind media inoculation method and bulked segregant method. The results showed that disease resistance was controlled by a single partial dominance gene,and a molecular marker RAPD-S329 linked with the gene loci for disease resistance to powdery mildew was found,the distance between them is 6.81±1.67 genetic unit.

Key words: Cucumis melo L, Powdery mildew, Gene for disease resistance, Molecular marker
