摘要: 为了建立甜瓜抗白粉病基因的分子标记辅助选择方法,以杂交组合1A151/恒进红瓤酥的6个世代群体 P1,P2,F1,F2,BCr和BCs为材料,利用风媒接种方法和分群法,研究了抗病基因的遗传和分子标记。结果表明,抗源1A151对白粉病菌的抗性由1对不完全显性抗病基因控制,并寻找到了1个与抗病基因位点连锁的分子标记RAPD-S329,其距离为6.81±1.67个遗传单位。

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
