Genetic divergence and hybrid performance over environments in faba bean



Genetic divergence and hybrid performance over environments in faba bean



Journal of Maharashtra Agricultural Universities 17(3): 428-430



Multivariate analysis was done to find out genetic divergence among 28 faba beans (Vicia faba) populations comprising 7 parents and 21 hybrids from all possible crosses among the parents after grouping them under better management (E1) and poor management (E2) conditions. The inter and intra cluster D2 values of distribution of hybrids vis-a-vis their respective parents across the clusters suggest that there was appreciable genetic divergence among the parents as well as hybrids. Geographical distribution had no relation with genetic divergence. Position of first pod, pods/plants, pod bearing nodes/plant, seeds/plant, 100 seed weight and harvest index accounted for most of the divergence in between the genotypes. A study of relationship between divergence of the parents and heterosis in the hybrids revealed that in general, the parental diversity was not associated with great heterosis.
