Abstract: The present investigation was undertaken to estimate the genetic variability, heritability and genetic advance for 20 parameters including, vegetative growth, flowering, pod and pod yield parameters etc. with thirteen genotypes of yardlong bean (Vigna unguiculata L. var. sesquipedalis) in a randomized block design with three replications during Rabi season of 2017-18 at AICRP on Vegetable Crops of Orissa University of Agriculture & Technology at Bhubaneswar, Odisha, India. Analysis of variance revealed significant differences among the genotypes for all the parameters studied indicating the presence of sufficient variability in the studied material. High magnitude of PCV and GCV were observed for pod yield per hectare, pod yield per plant, number of pods per plant and number of harvests suggesting the existence of wide range of genetic variability in the germplasm for these traits and thus the scope for improvement of these characters through simple selection would be better. High heritability were found with leaf area, pod yield per hectare and pod yield per plant and high genetic advance were recorded with pod yield per hectare, pod yield per plant and number of pods per plant indicated that the heritability is due to additive gene effects which may be improved through simple plant selection methods.
