Abstract: Genetic divergence analysis in 155 genotypes of lentil (Lens culinaris Medik.) by applying Mahalanobis’s D2 statistics indicated the presence of wider genetic diversity among the material for 13 characters. The genotypes were grouped into twelve clusters by Tocher’s method. Cluster V was the largest group of 34 genotypes, whereas cluster II was the second largest group consisting 29 genotypes grouped together. Cluster VI was the third largest cluster based on the genotypes (28 genotypes) followed by cluster IV (18 genotypes), cluster I (13 genotypes), cluster III (11 genotypes). Two clusters X and XII comprised of five genotypes each cluster and cluster VII and IX comprised of three genotypes in each cluster. The remaining cluster XI comprised four genotypes. Cluster VIII have only two genotypes indicating that this genotype is much more divergent than rest of the genotypes in the study. It was concluded that in general there was parallelism between genetic and geographic diversity. ClusterXIhad higher mean values for most of the desirable characters like seed yield per plant (3.69) followed by harvest index (48.91), number of pods per plant (108.75), number of peduncles per plant (64.57), number of primary branches per plant (15.77). The genotypes accommodate under cluster XI were found desirable for seed yield per plant (3.69 g).
