Coffee berry disease causes about 30 % national average crop losses every year in Ethiopia. This study was conducted to assess the distribution of coffee berry disease and test to know the pathogenicity of the disease on coffee landraces. Assessment of the disease was conducted in Bedeno, Boke, Habro and Darolebu districts from August to September 2011. Incidence and severity were recorded on 50 and 10 randomly selected coffee trees per farm; respectively. This disease was prevalent in all surveyed districts of Hararghe. The mean disease incidence was 51 % at Darolebu and 75 % at Bedeno and the mean disease severity was 26 % at Boke and 50 % at Bedeno. There was a highly significant difference among cultivar * isolate interactions. This indicated the presence of resistance sources in Hararghe coffee germplasms that may be exploited for coffee improvement purpose. Hence, it is important to conserve both in situ and ex situ and use sustainably the Hararghe coffee germplasms by conducting intensive selection from more diverse coffee populations and evaluations for resistance to coffee berry disease.
