Root Lesion Nematode (RLN; Pratylenchus thornei Sher and Allen) is a threat to chickpea production, either alone or in presence of Rhizoctonia bataticola. The effects of inoculation of 22 chickpea genotypes with P. thornei alone or with joint inoculation with R. bataticola were investigated in a pot experiment. Culture of P. thornei was developed under aseptic conditions on chickpea (JG 62). The populations developed on roots were inoculated @ 1000 P. thornei/genotype with four treatments: Nematode alone, Nematode + DRR fungus, DRR alone and untreated. Treatments were replicated five times. Observations were recorded after 40 days of inoculation from soil and roots of each treatment. During the course of investigation, the extents of damages developed by RLN and DRR individually as well as their combinations were recorded. The study revealed, above the four times rate of reproduction due to P. thornei was noticed in JG 62 over the ICCV2 and JG11, suggested that JG 62 is more vulnerable to RLN as well as DRR, while the ICCV 2 and JG11 showed resistance.
