摘要

Melon has an important role in agricultural production both in the world and Turkey. Acidovorax citrulli (Ac) and Aphis gossypii (Glover) are important factors that restrict protected cultivation and open field cultivation of melon. In this study, theresistance of 26 local melon genotypes was tested toward to Acidovorax citrulli. The isolate (Ac) of Acidovorax citrulli that virulent 83% was used in the tests. Pathogen inoculation was performed by injecting when seedlings were 3-4 true leaves. After15 days of inoculation, symptoms were scored according to 0-6 scale and evaluated (0: no symptoms, 1: 1-5% infected area, 2: 6-12% infected area, 3: 13-37% infected area, 4: 38-62% infected area, 5: 63-87% infected area, 6: 88-100% infected area). According to study test results, 11 melon genotypes which belong to 2 scales (6-12% infected area) were found as tolerant In the other treatment that carried out testing melon genotypes against A. gossypii there were 23 local melon genotypes. When the plants became 7-8 leaves, ten adults of A. gossypii were transferred to each test plant by a fine brush. Observations of individuals that survived for each plant were made at the end of 24 h and 72 h. At the end of 24 h, 0-7 individuals per plant were consideredas tolerant, and 8-10 individuals per plant as susceptible. At the end of 72 h, 0-5 individuals per plant were evaluated as tolerant while those over 5 were as susceptible. As a result, after 72 h; five genotypes were susceptible, two genotypes were medium tolerant and 16 genotypes were tolerant. Melon genotypes that are tolerant to both Ac and Aphis gossypii were included in the melon breeding program to develop new varieties.
