Abstract:
Thirty-five advanced mutant lines of French bean (Phaseolus vulgaris L.) along with one commercial check were evaluated in Randomized Complete Block Design (RCBD) with two replications during Kharif 2017-18 at College of Horticulture Bengaluru. Genotypic and phenotypic correlation studies for 15 characters were assessed for association between different characters, direct and indirect effects of component traits on pod yield per plant and other horticultural traits viz., plant Heigh, number of branches, number of leaves per plant, plant spread (N-S), plant spread (E-S), days to 50% flowering, pod length (cm), pod width (cm), number of flowers per plant, pod set percentage (%), Number of pods per cluster, number of pods per plant, number of seeds per pod, average pod weight (g) of French bean based on the evaluation of thirty three genotypes. A positive and significant correlation of pod yield with all the characters except days to flowering at both phenotypic and genotypic levels. Maximum emphasis should be given to characters plant height, number of branches, number of pods per cluster, number of pods per plant, and average pod weight for the improvement of pod yield per plant in French bean.
