An experiment was conducted to assess the genetic variability, broad sense heritability and genetic advance as percent of mean (GAM) with 100 urdbean genotypes at two locations, Punjab Agricultural University, Ludhiana and Regional Research Station, Gurdaspur during Summer, 2019. The analysis of variance indicated the significant variation present for all characters with significant GxE interaction across both locations. Highest phenotypic coefficient of variation (PCV) and genotypic coefficient of variation GCV was recorded for plant height at 90% pod maturity, pods per plant, yield per plant and harvest index for both locations indicating that an ample amount of phenotypic and genotypic variability is present in the material. Moderate to high heritability coupled with higher GAM observed for plant height at 90% pod maturity, nodes per plant, clusters per plant, biological yield per plant, yield per plant and harvest index suggested control of these characters through additive gene action and can be exploited via selection of superior genotypes for improvement of seed yield in urdbean breeding program.
