Abstract
Genetic divergence among 22 genotypes of lentil was estimated using D2 and principal component analysis. The genotypes under study fell into four clusters. The intra-cluster value was the maximum in cluster I and the minimum in cluster II. The inter-cluster distance was larger than the intra-cluster distance in all the cases suggesting the wider genetic diversity among the genotypes of different groups. The inter-cluster value indicated maximum distance between cluster I and II than cluster III and IV. Thus the genetically diverged genotypes of the clusters could be used as parent in hybridization program to get desirable genotypes. Cluster I had the highest mean for days to maturity, plant height, pods/plant and per plot yield while cluster II and III had the highest days to first flowering and 100 seed weight, respectively. Genotypes with these characters in respective groups would, therefore, offer a good scope of improvement of lentil through selection.

Highlights
Multivariate analysis is a useful tool in quantifying the divergence between biological population at genotypical level and to assess relative contribution of different components to the total divergence both at intra and inter-cluster levels (Murty and Arunachalam, 1966, Ram and Panwar, 1970, Sachan and Sharma, 1971 and Jatasra and Paroda, 1978)
The present study was, undertaken to analyze the genetic divergence of 22 lentil genotypes collected from different parts of Bangladesh
The first two principal axes accounted for 61.17% of total variation among the six characters describing 22 genotypes
Summary
Multivariate analysis is a useful tool in quantifying the divergence between biological population at genotypical level and to assess relative contribution of different components to the total divergence both at intra and inter-cluster levels (Murty and Arunachalam, 1966, Ram and Panwar, 1970, Sachan and Sharma, 1971 and Jatasra and Paroda, 1978). Such a study permits to select the genetic divergent parents to obtain the desirable recombinant in the segregating generations. The present study was, undertaken to analyze the genetic divergence of 22 lentil genotypes collected from different parts of Bangladesh
