Knowledge of phenotypic diversity is important for devising the breeding strategy for faba bean (Vicia faba L.) program in Ethiopia. This study was conducted to determine phenotypic diversity among 50 faba bean genotypes collected from the major faba bean growing areas of Ethiopia and International Centre for Agricultural Research in the Dry Areas (ICARDA). The genotypes were evaluated at two locations using a randomized complete block design with three replications. All agronomic data, yield and yield component, chocolate spot (Botrytis fabae) disease incidence disease severity were collected and analyzed using analysis of variance, principal component analysis and the Shanon-Weaver index, using SAS V9.3 and PAST V 3.0 software. There were significant differences (p< 0.001) among the genotypes on most of phenotypic traits, chocolate spot disease severity, yield and its component. The genotypes were categorized into three clusters and different sub-groups. Six principal components were identified explaining more than 80% of the total variation. The Shannon-Weaver diversity index, which ranged from 3.82 for pod weight to 7.15 for number of basal branches per plant, revealed high diversity among and within the genotypes. The observed high variation among the faba bean genotypes would be exploited in new faba bean varieties development program
