Abstract:

The present investigation was done to study the influence of root exudates on the sclerotia/conidia germina- -tion and growth of the test fungi (Sclerotium rolfsii, Rhizoctonia solani and Fusarium oxysporum f.sp. ciceri). For this purpose, root exudates were collected from four chickpea varieties i.e., JG 315 (Resistant), JG 74 (Moderately resis- -tant), ICCV 2 (Susceptible) and L 550 (Highly susceptible). Maximum sclerotia/conidia of test fungi germinated in the root exudate of highly susceptible variety (L 550) and it was least in root exudate of resistant variety (JG 315) as compared to control. Similarly in poisoned food technique, the maximum colony diameter of test fungi were recorded on root exudate of highly susceptible variety (L 550) and it was minimum on root exudate of resistant variety (JG 315). This indicated that root exudate of resistant varieties released some toxic chemicals which prevent the growth of wilt complex pathogens.
