Description Lentil (Lens culinaris Medik) is an important crop in Ethiopian highlands. Its productivity is very low
due to low yielding landraces and other factors. The objectives of this study were to classify groups of
genotypes based on morphological diversity, identification of the major traits contributing to the diversity
and identify superior genotypes for breeding. Eleven variables analyzed by Mahalanobis’s generalized
distances (D2), Principal Components Analysis (PCA), and a cluster analysis following the method of
the Unweight Pair Group Method using Arithmetic Averages (UPGMA). The result showed the existence
of considerable genetic diversity among lentil genotypes, for yield and yield components indicating the
scope and guarantee for use in the breeding programmes. The most important traits that contributed to
genetic divergence were above ground biomass, seed yield, number of seeds per plant, days to maturity
and number of pods per plant. The lentil accessions were grouped into 6 major and 15 sub clusters
characterized by distinct morphological feature irrespective of their origin.
