Studies of Genetic variability, heritability and genetic advance for yield and related traits in French bean (Phaseolus vulgaris L.)

Author(s): Dinesh Kumar Singh, DP Singh and Shashank Shekhar Singh
Abstract: The present investigation was carried out using forty French bean genotypes during January-may of 2016 to measure the extent of variability for further use in breeding programmes. Highly significant differences among the genotypes were observed for all traits under study. Phenotypic coefficient of variation was higher than that of genotypic coefficient of variation. The characters like number of pods per plant followed by green pod yield per plant (q) and green pod yield per plant (gm) showed high genotypic and phenotypic coefficient of variation with high heritability coupled with genetic advance. A positive and significant correlation of pod yield per plant (q/ha) with number of pods per plant, number of clusters per plant, green pod yield per plant (gm) and plant height was observed. Path analysis exposed that green pod yield per plant (gm) followed by number of clusters per plant, seed length and pod width have highest positive direct effect on green pod yield per plant (q). Therefore, it might be concluded that number of pods per plant, number of clusters per plant and green pod yield per plant (gm) should be given due consideration for the improvement of pod yield per plant in French bean.
