Abstract: The investigation was carried out in a complete randomized block design with three replications with thirty lentil genotypes. The main objective of present research work was to assess the genetic divergence for yield and yield contributing character. The cluster II showed maximum number of genotypes. Generally, the genotypes within a group showed little divergence from each other than from the genotypes of different groups. The relative divergence of each cluster from other cluster has been of high order and divergence particularly between the members of cluster IV with members of all other clusters. The large inter-cluster distance between members of any two clusters indicates that genotypes falling in such clusters would be more genetically divergent. Therefore, the crosses between genotypes selected from those clusters may give desirable transgressive segregants. Cluster I reported lowest mean value for days to flowering (61.93 days) and days to maturity (123.75 days). Number of fruiting branches contributed maximum variance (29.66%) followed by 100 grain weight (22.42%), number of seeds per pod (11.26) etc. Therefore, these characters should be given more stress for the selection and choice of parents for hybridization. In view of considerable genetic diversity in lentil found in the present study, their appearance had sufficient scope for genotypic improvement through hybridization between the genotypes from divergent clusters.
