Abstract: Chickpea (Cicer arietinum L.) is an important pulse crop, which belongs to family Leguminaceae, chickpea having 2n=16 number of chromosomes. Chickpea is native of India and tropical, subtropical and temperate regions. It is ranked 3rd after common bean. Pulses play an important role not only from economical point of view but also due to their nutritional value. Chickpea is valued for their nutritive seeds with high protein content, 25.3-28.9 per cent after dehulling. Carbohydrate 61.5 per cent, fat 4.5 per cent and vitamins 2.44 per cent. Variability among the ten isolates of Fusarium oxysporum f. sp. ciceri (FOC), collected from different locations of Parbhani district in Maharashtra. Ten isolates were studied in respect of cultural, morphological characters and Pathogenic variability. Result of the above study reveals that pathogenic variability has been established by inoculating ten days old seedlings of different cultivars individually with the Fusarium oxysporum f. sp. ciceri isolates. JG 62 exhibited susceptible reactions to FOC isolates with highest percentage of seedling mortality whereas, JG 315 and BCP-160 were exhibited resistant reactions to the FOC isolates with lowest mortality percentage due to wilt varied within the cultivars. Cultural studies of all isolates of F. oxysporum f. sp. ciceri resulted that isolates differ in the growth rate, types of colony, sporulation, and pigmentation on Potato Dextrose Agar is being favorable for luxuriant growth for all the isolates and dry weight of mycelia mat growing them on Potato Dextrose Broth medium. Morphological studies of different isolates of Fusarium oxysporum f. sp. ciceri concluded resulted in the variations in size, septation and formation of chlaymadospores.
