Morphological variability and pathogenic reactions of Fusarium oxysporum f.sp. ciceri isolates to cultivars of Chick pea

All five isolates were found morphologically different and mycelial growth in different media was observed. Isolate Foc-5 preferred Czapek Dox medium for maximum growth (78.5 mm) while poor growth of Foc-4 (53.1 mm) in Asthan and Howkers medium. Isolate Foc-1 produced white dull colony whereas Foc-2 and Foc-4 rendered brown and pinkish white colony, respectively. Overall, biggest micro and macro conidia were found in isolates Foc-5 and Foc-3, respectively. Whereas, isolates Foc-2 and Foc-5 produced smallest micro and macro conidia, respectively. Most of isolates were more or less pathogenic to all tested chick pea cultivars. Awrodhi found resistant to most of the tested isolates, except Foc-5. Cultivar K-850 was found highly susceptible to isolates Foc-2 and Foc-5 and remaining three isolates rendered susceptible reaction.
