Variability, Heritability, Correlation and Genetic Divergence Studies in Dolichos Bean (Lablab purpureus L.)

Variability, heritability, correlation and genetic divergence were studied in 30 strains of dolichos bean (Lablab purpureus L.) for various growth and yield attributing parameters. High phenotypic and genotypic coefficient of variation was found in number of flowers per cluster, fresh green pod yiel...

High heritability and expected genetic advance was found in number of flowers per cluster, vine length, weight of 10 green pods, fresh green pod yield per plant, and green pod yield per hectare.
