Abstract:
Fusarium oxysporum f. sp. ciceri causing wilt disease is an major loophole in the lesser productivity of chickpea in Marathwada region (Maharashtra). It is an highly variable pathogen. However the high pathogenic variability may limit the effectiveness of resistant cultivars. So the present study was conducted to determine the pathogenic variability of Fusarium oxysporum f. sp. ciceri isolates collected from Marathwada region (Maharashtra) using sick soil inoculation method and water culture method. In sick soil inoculation method, FOC-8 isolate (Parbhani) was proved most virulent on chickpea wilt susceptible cultivar JG-62 with mortality percent (89.33%), followed by FOC 5 (Nanded isolate) and FOC 1 (Hingoli isolate) with 86.66% and 84.48% respectively. In water culture method, all isolates of Fusarium were showed 100 percent mortality of chickpea seedlings, where isolate FOC-8 (Parbhani isolate) showed early symptoms on seedlings.
