Identification and Preliminary Genetic Analysis of Resistance to Powdery Mildew on Melon

doi:10.3321/j.issn:1000-7091.2002.03.025

Abstract

Abstract: We studied the resistance to powdery mildew in 357 varieties of melon in air-conditioned greenhouse by wind media inoculation.The result showed that 69 varieties were resistant,52 of which come from foreign varieties,10 of which from seed markets or research institutes in China.6 var.makuw a makino and 1 var.f lexuosus naud were resistant in 133 landraces on Melon.This indicated that the population of landraces has resistant genes which have a potential value to melon breeding.The number of resistant plants was bigger than that of susceptible plants in inbreeding off spring of resistant sources,and the inheritance of these resistant genes may be dominant.

Key words: Melon, Powdery mildew, Identification of resistant sources, Genetic analysis
