Variation in the reaction of lake van basin melon genotypes to Fusarium oxysporum f.sp. melonis

The reaction to Fusarium oxysporum f. sp. melonis (F.o.m.) race 0 and 1,2 of fifty Cucumis melo L. genotypes collected from Lake Van Basin was determined by inoculating melon genotypes with sand culture of F.o.m. race 0 and 1,2, for the pathogenicity test. Melon seedlings were evaluated with two different scales based on disease incidence and vascular discoloration. The disease frequency on the 50 melon genotypes varied differently. It was found that although there were several resistant melon genotypes to F.o.m. race 0, most of the melon genotypes were found susceptible to F.o.m. race 1,2. © 2012 Friends Science Publishers.
