Abstract: Components of genetic variation for pod yield and other associated yield characters in lablab bean have been estimated through six-parent diallel cross in F2 generation. Additive as well as dominance components were significant for all the characters in both environments. Diallel analysis after Hayman’s approach suggested environmental interaction for flowering date, pods/inflorescence, inflorescence/plant and pod yield/plant. Complete dominance was observed for flowering date in environment 2, flowers/inflorescence and pod yield/plant in environment 1 and pods/inflorescence, pod width in both environments. Over dominance was displayed for flowering date in environment 1 and for pod yield/plant in environment 2. Partial dominance was found for flowers/inflorescence in environment 2 only but for inflorescence/plant, pod length and 10-pod weight in both environments.
