Abstract

Sixty one lentil accessions representing four wild species of genus Lens were evaluated for 20 quantitative traits in a replicated experiment in pots in the glass house. Principal component analysis (PCA) was carried out using character correlation matrix. First three components (PC,s) accounted for sufficient variation for differentiation of accessions in two dimensional space. Relationships among accessions as obtained by PCA suggested that L. ervoides was separated from L. orientalis and L. odemensis on first principal axis. Latter two species were also separated from L. nigricans. It was also revealed that the first principal component was a linear comuination of size characterics, indicating their important role in differentiation of accessions as well as species
