Detection of Resistant Sources against Collar Rot of Chickpea Caused by Sclerotium rolfsii Sacc. Under Field Conditions

One hundred eighty five chickpea entries received from AICRP (All India Coordinated Research Project) on Chickpea, were evaluated at Raipur under field condition during the year 2016-17 to identify sources of genetic resistant against collar rot disease incited by the fungus Sclerotium rolfsii. The fungus was isolated from diseased chickpea plants collected from research farm at seedling and vegetative stage of the crop, purified and maintained on PDA for further screening process. Mass culture of the pathogen was prepared on wheat grains media and inoculated in collar zone of chickpea plant, 15 days after sowing. Out of 185 chickpea entries only 5 entries viz., GNG 2331, JG 2016-9605, IPC 2012-98, RVSSG-38 and GL 12003 exhibited moderately resistant response while, the remaining were susceptible to highly susceptible for collar rot of chickpea.
