Abstract:
The present study was conducted to identify the nature and magnitude of genetic divergence among fifty two genotypes based on phenotypical traits using the multivariate analysis. Based on cluster analysis, the genotypes were best fitted into three clusters. The maximum and minimum genotypes grouped in cluster I (50) and minimum were in Cluster II (1) and cluster III (1) respectively. The maximum intra-cluster distance was shown by cluster I (D²=5.07) indicating maximum difference among the genotypes within and the minimum value was shown by cluster II and cluster III. Maximum value of inter-cluster distance (D²=16.76) was recorded between cluster I and cluster III revealing that the genotypes of these clusters were highly diverse from others and can be used as divergent parents for hybridization and selection. Thus, for getting high heterosis for recovering transgressive segregants, genotypes from cluster I and III can be used as distant parents in any breeding programme for successful pea improvement. The results of present study could be exploited in the future genetic improvement programme of pea genotypes in Madhya Pradesh region.
