Abstract:
The present investigation “Assessment of genetic diversity in exotic collections of fava bean (Vicia faba L.)” was carried out to assess the extent of genetic variability and divergence of yield contributing characters of seed yield per plant in forty-six genotypes of fava bean at Vegetable Research Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.) during Rabi 2019-20. The analysis of variance revealed highly significant differences among the forty-six fava bean genotypes for seed yield per plant traits indicating the presence of sufficient variability for all the traits under the study. All the traits indicating the presence of high degree of variability and better scope for further crop improvement. The observations for ten characters were recorded as well as multivariate technique; cluster analysis was applied. The fifty genotypes were grouped into eight distinct clusters on the basis of Euclidean distance. The maximum inter-cluster distances for seed yield were recorded between Cluster V & VII and Cluster V & VIII respectively, indicates the presence of wide diversity between these clusters. Therefore, genotypes from these clusters can be selected for hybridization programme to get desirable recombinants. Number of clusters per plant contributed the maximum per cent towards genetic divergence in forty-six genotypes of fava bean, indicates the presence of wide variability for these traits among the studied genotypes. Therefore, simultaneous selection for above traits is suggested for the improvement of seed yield per plant in fava bean.
