Abstract
Combining ability analysis carried out for ten characters using six diverse parents in field pearevealed that variance due to gca and sca were highly significant for days to maturity, plantheight, number of pods per plant, number of seeds per pod, 100 seed weight and seed yield perplant, indicating the importance of both the additive and non-additive genetic components ofvariation. The parents DDR-44 and Rachna were good general combiners for grain yield andbiological yield; HUP-2 for 100 seed weight and maturity; DMR-7 for number of pods per plant;HUDP-6 and DMR-41 for plant height; and HUP-2 and DDR-44 for protein content. The crosscombinations viz., HUP-2 x DDR-44, Rachna x DDR-44, HUDP-6 x DMR-41 and DMR-7 x DMR-41 were the best with significant sca effects and high per se performance for seed yield. Heterosisover standard check (SC) was studied for ten characters in 15 hybrids. Considering the values ofstandard check, high heterotic effects were observed for days to maturity, protein content and100 seed weight; moderate for days to flowering, number of seeds per pod, plant height andnumber of branches per plant. High heterotic response for seed yield per plant was mainly due topods per plant, number of seeds per pod and 100 seed weight
