Abstract
Downy and powdery mildew are economically important diseases in all cultivated plant species. Pathogens Pseudoperonospora cubensis, Sphaerotheca fuliginea and Erysiphe cichoracearum are one of the limiting factors of successful melon production in agro-ecological conditions of Serbia. Cultivation of less susceptible and resistant genotypes against pathogens is the basis for successful melon production. Consequently, 30 melon genotypes were tested against the causative agent of downy mildew P. cubensis in the fi eld conditions. Also, the susceptibility of 4 lines originating from Ananas melon against causative agents of powdery mildew S. fuliginea and E. cichoracearum in greenhouse was determined. The lowest susceptibility to P. cubensis was expressed in the melon genotypes D11, D7, D13 in the fi rst and D30 in the second evaluation. The highest susceptibility to the mentioned pathogen was expressed in 8 genotypes in the fi rst and 15 genotypes in the second evaluation. In terms of the susceptibility of the tested lines to causative agent of powdery mildew, line A 2/1 was found as most resistant, and line A 3/4 as the most susceptible.
