Cotton is an important industrial plant because of its fiber and seed. Root-knot nematodes (Meloidogyne spp.) are among the harmful of cotton due to its parasitic effects, as in other plants. On account of the adverse effects of nematicides used in this struggle against to humans and environmental health, it is necessary to develop durable cotton genotypes as an alternative to chemical struggle. This study was conducted in Kahramanmaraş province in 2016 for determine the reactions of five new cotton genotypes (F7) which obtained from Nazilli 84 S (♀) x Ashgabat 100 (♂) cross combination against to race 1 and race 2 of M incognita and race 1 of M javanica. M. incognita and M. javanica are root-knot nematodes. For this purpose, an experiment with 5 replications was carried out in the climate chamber, with a randomized plot design.
As a result of study, G1, G4 and G5 cotton genotypes were found resistant to both race 1 and race 2 of M. incognita. Whereas G2 and G3 genotypes were found susceptible to race 1 of M. incognita, but resistant to race 2. On the other hand, all cotton genotypes found to be resistant to race 1 of M. javanica.
