Introduction: Cucumber mosaic virus (CMV) is one of the most common pathogens of cucurbits plants in the world. The best way to manage the disease is to identify and cultivate resistant cultivars. Materials and Methods: Reaction of 40 genotypes or cultivars of cucurbits plants including Cantaloupe, cucumber, melon, squash and watermelon were evaluated for a CMV isolate from subgroup IB under greenhouse conditions in a completely randomized design with 10 replications per treatment. The plants were inoculated with CMV-infected tobacco extract at the cotyledon leaf stage. Up to four weeks after inoculation, their reaction was determined based on symptom severity index and absorption index in ELISA test (OD405). Results: Genotypes were classified into five groups: highly sensitive, sensitive, relatively resistant, resistant and completely resistant. Conclusion: Cultivation of completely resistant or resistant genotypes for disease management can be recommended.
