Chocolate spot (Botrytis fabae) is one of the major diseases threatening faba bean (Vicia faba L.) production and limiting its productivity in Ethiopia. Even though several improved faba bean varieties were released in Ethiopia, researches’ have not been done especially in study area, Western Ethiopia. Therefore, this experiment concerned to assess the epidemics of chocolate spot disease on the released varieties per the objectives to measure the responses of faba bean varieties to chocolate spot disease and to select the likely varieties of faba bean for the study areas at Guduru and Shambu experimental sites in the 2016 and 2017 main cropping season. From these field experiments disease severity and AUDPC were found significantly different (P < 0.05) among the varieties in both locations and seasons. The host reaction at Shambu showed that Mesay and Moti varieties were found moderately susceptible whereas, FB Didia and Degaga varieties were found moderately resistant in both years, while at Guduru Obse, Hachalu, and Tesfa varieties were found moderately susceptible whereas, Kasa and Bulga-70 varieties were found moderately resistant in the 2016 cropping season. It shows as the faba bean varieties were reacted differently to a disease for these studies.
