ABSTRACT
Forty germplasms of berseem were assessed for the nature and magnitude of genetic divergence based on tendifferent traits of economic importance including green forage yield per plant following Mahalanobis’s D2statistics. The germplasms were grouped into seven clusters. The grouping showed one mono-genotypic cluster(Cluster II), while others comprised of two (Cluster IV), three (Cluster III), four (Cluster V), five (Cluster VII), nine(Cluster I) and sixteen germplasms (Cluster VI). The maximum inter-cluster distance was observed betweenCluster II and IV (D2 = 51.898) and minimum between Cluster I and VI (D2 = 5.523). The maximum intra-clusteraverage D2 value was observed for Cluster VII (D2 = 7.354) and minimum for Cluster II (D2 = 0.000). For greenand dry forage yield per plant, the maximum intra-cluster group mean was found for Cluster III (D2 = 12.65) andCluster V (D2 = 2.41) respectively. Green forage yield per plant contributed maximum (21.45 %) and minimumcontribution was through leaf: stem ratio (2.19 %) towards the total genetic divergence.
