Biometrical studies in pole type dolichos bean (Lablab purpureus L.) under semi arid condition of western Maharashtra

Thirty seven genotypes of Dolichos bean (Lablab purpureus L.) were evaluated to study the genetic variability, heritability and genetic advance for green pod yield and yield attributing characters. The genotype DBP-13-03 recoded highest green pod yield and found promising. Genotypic coefficient of variation was higher for green pod yield plant⁻¹, pod yield plot⁻¹, pod yield hectare⁻¹, average weight of 10 pods and number of pods vine⁻¹. All the characters under study were highly heritable in nature. High heritability estimates associated with high genetic advance as per cent of mean was observed for the yield of green pod plant⁻¹, pod yield⁻¹, pod yield hectare⁻¹ and average weight of 10 pods, which indicated that these characters had additive gene effect and therefore, they may be considered as more reliable for effective selection.
