Evaluation of Tomato Cultivars Resistance to Root-Knot Nematode (Meloidogyne javanica chitwood, 1949)

In the present study resistance of tomato cultivars including Chef, Ch-Falat, Early Urbana Y and Super Strain B was evaluated against root-knot nematode with five replications and randomized complete block design (RCBD) as factorial was used. After 7 weeks dry and wet weight of root and stem, length of stem, numbers of gall and egg masses, final population and reproduction factors were evaluated. The results of experiments showed that on the number of galls and egg masses per gram of soil cv. Chef hadn't statically differences at probability 5% with Ch-Falat and Super Strain B cultivars. On the final population and reproduction factors all cultivars showed significantly differences at probability 5%. The highest amount of plant growth factors was observed in Super Strain B-0 and while the lowest amount of stem length, root and stem wet weight was belong to Early Urbana Y-2000, the minimum amount of root and stem dry weight was recorded on Early Urbana Y-0. Our observation showed that cultivars hadn't sufficient resistance against of the root knot nematode, Meloidogyne javanica.
