Fusarium wilt, caused by Fusarium oxysporum f. sp. capsici (FOC) is one of the major pathogens that constrained productivity of hot pepper in Ethiopia. The present study was conducted to characterize FOC isolates and evaluate the pathogenic variability of FOC isolates from Central Rift Valley of Ethiopia. Collection of diseased Fusarium wilt samples were carried out in Alaba, Adama, Adami Tullu Jiddo Kombolcha, Dugda, Mareko and Meskan districts, during the 2018 main cropping season. FOC isolates were characterized based on morphological features and pathogenicity test under greenhouse conditions. Regarding the characterization of FOC isolates, from the collected 70 root and stem samples, 49 were identified as F. oxysporum based on macroscopic (colony color, shape and margin) as well as microscopic characteristics (production of microconidia, macroconidia and chlamydospores).
