In order to study the reaction of 15 cucumber cultivars to the root-knot nematode, Meloidogyne javanica, after nematode purification on the tomato cultivar Rutgers, with the help of morphological characters and species-specific primers the nematode species was identified. Experiment was conducted on the basis of completely randomized design in the greenhouse conditions using sterile soil. In resistance assessment of different cucumber cultivars to this nematode, the growth factors of the host plants and nematode reproduction were used with different methods. Results showed that all the greenhouse cultivars used in this experiment were susceptible to M. javanica and only two local cultivars from Isfahan (Chambar and Dastgerdi) recognized as tolerant. Also the amount of vitamin C, Calcium and Potassium minerals as well as leaf area index decreased in infected plants.
