Root-knot nematode (Meliodogyne incognita) is the major pest on bell pepper which causes a yield loss upto 15%. Among the non chemical methods available to control them; the use of resistant cultivars is considered one of the most effective and environmentally safe alternatives. An investigation was carried out to assess the tolerance level of five available cultivars viz., Indam Mamatha, Chocolate Wonder, Indra, Indam Supergold and California Wonder against M. incognita. Among the five bell pepper cultivars screened none of them was found to be resistant to root-knot nematode. However, the least number of galls were recorded in the roots of Indam Mamatha with least root-knot index followed by Chocolate Wonder. The cultivar, Indra was highly susceptible to M. incognita.
