Abstract

In order to investigate and evaluate the resistance of cucumber to powdery mildew, 7 hybrids of cucumber were evaluated in three replicates, in two conditions. Genotypes were cultured with the application of fungicide (Metalaxyl) or without the application of fungicide. The experiment was conducted in the polycarbonate greenhouse. The study was arranged in the form of a factorial design in a completely randomized design. In this research traits such as the number of female flowers, the number of male flowers, the length of the pedicle, the length of the ovary, the number of lateral branches, plant length, fruit length, average leaf area, average infected leaf area, number of fruits per plant were measured. The results showed that the highest value of fruit number without chemical control belonged to the genotype 39-2-2×36-5-2. While with chemical control, the 36-5-2×22-3-4, and 39-2-2×36-5-2 had the highest number of fruits per plant. Also, in terms of the number of fruits per m2, the least amount of fluctuation in the two conditions and the highest stability belonged to the 50-2-3×22-3-4, respectively. 39-2-2×36-5-2 showed the highest number of female flowers in both conditions with and without fungicide application. 50-2-3×22-3-4 with the lowest amount of fluctuation in two conditions and the highest stability was known for cultivation in two conditions with chemical control and without chemical control.
