Abstract:
An experiment was conducted in the net house of Department of Nematology, A. A. U. Jorhat, during the rabi season of 2020-2021 to evaluate the different germplasms of bitter-gourd (Momordica charantia L.) for resistance against root-knot nematode, Meloidogyne incognita. The pot experiment was carried out in a completely randomized design with five replications. Second stage juveniles of M. incognita at 1 J2 per cc soil were inoculated into the rhizosphere of 15 days old seedlings and the Root Knot Index for each germplasm was calculated after 45 days of inoculation. Among the screened germplasms, four germplasms were found to be moderately resistant, ten germplasms were found to be susceptible to root-knot nematode, M. incognita.
