An experiment was conducted to study the genetic variability, heritability and genetic advance for yield and yield traits in yard long bean. Four parents and three hybrids of yard long bean were evaluated in a field experiment in randomized block design with three replications during Kharif 2020. Analysis of variance revealed significant differences among the parents and hybrids for most of the characters studied. PCV expressed higher value than corresponding GCV for all the traits. High phenotypic and genotypic coefficient of variation (PCV and GCV) was observed for pod length (52.86 and 52.79) and pod weight (32.07 and 31.82). High heritability (broad sense) was observed for pod length (99.76) and hundred seed weight (99.73) with high genetic advance as per cent of mean which suggests that simple selection breeding method would be effective in improving the traits
