279accessions of Enset ventricosum were tested at ArekaAgriculturalResearchCenterin a non-replicated field. The objectives of the study were to assess the diversity of these accessions based on key morphological descriptors and evaluate the accessions based on yield and yield related traits. Data on six qualitative and 22 quantitative traits were collected and subjected to various statistical analyses. Cluster analysis based on qualitative characters indicated the formation of six clusters and existence of variability, based on their leaf, midrib and petiole traits. The result of Shannon-Weaver diversity index (H`) showed thatlowlevels of diversity existed among the 279 Enset ventricosumaccessions based on the frequency of the phenotypic charactersconsidered. Analysis of variance for quantitative characters indicated significant variation among the accessions in all the 22 yield and yield components of an enset plant. Cluster analysis based on quantitative characters indicated the formation of six clusters and showing cluster five with the highest values for yield and yield components for the majority of the characters followed by cluster IV. The cluster and distance analysis of quantitative characters pointed out the distance between most of the clusters were highly significant (P < 0.01) suggesting diversity among accessions in different clusters. The maximum inter-clusters distance (D2 = 256.45) was noticed between cluster III and V followed by I and V (D2 = 228.59) and II and V (D2 = 206.10) suggesting diversity between these groups. Correlation study between various quantitative characters showed highly significant association among characters. Maturity time has a negative correlation with yield and yield components of an enset plant.
