Genetic Variability and Genotypic x Environment Interaction for Seed Yield and Related Traits in French Bean Germplasm

摘要

Thirty-three accessions of bush type French bean were evaluated in Randomized Complete Block Design with three replications for two seasons during summer 2008 and 2009 at Vegetable Farm, H.R Agricultural University, Palampur to explore the genetic variability and G x E interaction for yield and yield related traits. High genotypic and phenotypic coefficients of variations were observed for seed yield/plant followed by moderate for majority of the traits. A positive correlation was observed for seed yield/plant with fresh pod yield/plant, pods/plant, 100-seed weight, average pod weight, plant height, pod length, biological yield/plant and branches/ plant. On the basis of correlation and path coefficient analysis, selection on the basis of pods/plant,fresh pod yield/plant, 100-seed weight, plant height and branches/plant would be a paying proposition for evolving high yielding genotypes. A significant association between seed yield/plant and fresh pod yield is of significance to explore the possibilities to develop dual purpose French bean variety(ies) both for vegetable and dry bean.
