Resistance of Some Cultivars of Tomato and Potato to Meloidogyne javanica*

Abstract

Meloidogyne javanica is commonly encountered root-knot nematode species in the Western region of the Libyan Jamahiriya. Some cultivars of tomato and potato were screened against this namatode. Potato cultivars showed better resistance than tomato cultivars. Most of the tomato cultivars were found to be highly susceptible; only one (Tobol No. 748 VFN RF] RS) showed resistance. On the other hand, most of the potato cultivars were slightly susceptible. Two of the potato cultivars. Cardinal and Ajax exhibited resistance.
