Abstract:
Genetic diversity analysis was conducted at Vegetable Research Farm, College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh in 22 diverse genotypes of Indian bean for 17 yield and yield attributing traits and grouped in to five clusters through Mahalanobis’ D2 analysis. Out of the 5 clusters, maximum number of genotypes were accommodated in cluster I with 13 genotypes, followed by cluster II with 5 genotypes, cluster V with 2 genotypes, cluster III and IV were solitary containing single genotype each namely CHF-22 and CHF-10 respectively. Divergence study revealed pod yield per plant contributed maximum per cent to the diversity followed by number of branches per plant, plant height, number of cluster per plant, green pod crude protein, days to 50% flowering, number of flower per cluster and number of pods per cluster. Maximum inter cluster distance was observed between cluster II and V which indicated that the genotypes within these clusters were highly divergent and desirable to select for further crop improvement programme.
