Genetic variability, heritability and genetic advance in French bean (Phaseolus vulgaris L.) genotypes

Twenty five genotypes were evaluated to study the genetic variability, correlation coefficient and path coefficient. The experiment was set up in a randomized block design. The coefficients of variation for both the genotypic coefficient variation (GCV) and the phenotypic coefficient variation (PCV) were high for plant height, number of pods per plant, pod length. High heritability coupled with genetic advance was found for days to 50% flowering, plant height (cm), number of branches per plant, number of pods per plant, pod length (cm), seed width (mm), 100 seed weight (g), seed yield per plant. A positive and significant correlation of seed yield per plant with days to 50% flowering and days to maturity was observed.
