Genetic variability, heritability and genetic advance studies in Dolichos bean (Lablab purpureus L.) genotypes

Abstract

The present investigation was carried out to study the genetic variability, heritability and expected genetic advance for 18 traits in dolichos bean. The experimental material comprised of 12 genotypes of Lablab purpureus. The genotypes GL 243, Culture 47 and GL 671 are superior based on mean for pod yield. Wider variability was observed for plant height, number of secondary branches per plant, number of pods per inflorescence, number of inflorescence per plant, mean pod weight, number of pods per plant, 100-seed weight, pod yield per plant and pod yield per hectare. All these characters also recorded high heritability and genetic advance. Hence selection will be effective for these traits.
