The production of chickpea is severely limited by Fusarium oxyspomm f.sp. ciceris. In this study, eleven isolates of pathogen from different fields of Kurdistan province (Kamiaran, Divandareh, Marivan, SanandaJ and Dehgolann) were obtained and pathogenicity test was evaluated on the Kaka cultivar in greenhouse condition. of the inoculum of the pathogen was obtained using wheat seeds in flasks and the infected seeds were added to soil .. In each pot containing infested soil three seeds of Kaka cultivar was sawn. The experimental design was a completely randomized design with four replications for every isolate. Statistical analysis was performed using SAS statistical software and mean comparison was done by Duncan's test (P<%5). Eight weeks after inoculation, incidence and severity of diseased plants was calculated (Campbell and Madden 1990). According to observations, all isolates in respect to disease incidence were sign ificant in comparison to healthy controls, but disease severity in isolate F II ranked with the healthy cont rol. These results indicated that different races of Fusarium wilt highly pathogenic on the different cultivars of ch ickpea arc active in Kurclistan province
