An investigation was undertaken to evaluate forty three progenies from F5generation of Lablab bean along with one local check for estimation of genetic variability, heritability and genetic advance. A wide range of variation was observed for yield and its component traits among the progenies under study. Highest and lowest coefficient variation was noticed in the seed yield per plant and days to maturity respectively. The traits days to initiation of flowering, days to fifty per cent flowering, days to maturity and plant height showed narrow differences between PCV and GCV. In general PCV was higher in magnitude than GCV. The traits viz; seed yield per plant, peduncles per plant, primary branches per plant, hundred seed weight, number of pods per plant and plant height recorded high magnitude of GCV and PCV along with moderate to high heritability. High estimates of heritability coupled with high genetic advance as per cent of mean was observed for seed yield per plant, peduncles per plant, primary branches per plant, plant height and hundred seed weight indicating additive gene expression and more reliable for effective selection in improvement of these traits. Based on mean performance, the genotypesviz;G-9, G-36, G-14, G-10, G-40, G-4, G-41, G-22, and G-42 were found promising for the important yield component traits.
