Two successive tomato varieties (lines) were identified for resistance to nematodes by direct identification. The results showed that three materials (T17-1, T18-1, T19-1) did not show any disease, and the disease resistance was up to the level of immunity. Most of the other varieties (lines) were not resistant to nematode disease.
