An experiment was conducted involving 10 diverse parents and their 24 hybrids obtained by line x tester mating design laid out in randomized block design with three replications. The analysis of variance revealed presence of ample variability for fifteen quantitative traits studied. The cross combination GP-167 x Katargam exhibited highest mean values and standard heterosis over check variety Gujarat Papadi-1 for green pod yield per plant followed by GP-167 x GNIB-21 and GP-189 x GNIB-21. The hybrids GP-167 x Katargam and GP-167 x GNIB-21 were also superior considering heterobeltiosis and standard heterosis. These hybrids had high heterotic effects over better parent as well as standard check. The cross combination GP-kh-64 x Kapasi exhibited highest <em>per se</em> performance and standard heterosis for seed yield per plant followed by GP-kh-120 x Katargam and GP-158 x Manchhi. The superior hybrids may be advanced to obtain transgressive segregants and purelines for higher green pod yield per plant. As the development of hybrid variety is not possible in Indian bean, diallel selective mating system may be adopted for improvement of remaining traits followed by some sort of biparental mating and recurrent selection.
