Abstract:
The chickpea wilt caused by Fusarium oxysporum f. sp. ciceri is seed and soil borne disease at is considered to be as one of the major factors of low productivity. The present study was conducted to determine pathogenic variability of twenty five isolates collected from different agro ecological regions of India. In the reference to isolates corresponding to four races of chickpea pathogen. The highly wilt susceptible genotype JG-62 by pot culture (sick soil) method. The five isolates were found moderately resistant to wilt, fifteen were found highly virulent and five were strongly virulent to wilt disease in soil inoculation method. None of the isolates found non-pathogenic/avirulent in the experiment. This is an alarming situation for chickpea grower. The virulence assay does not show correlation between virulence patterns with geographical origin of isolate, mycelium growth rate, pigmentation.
