Fifteen C. annuum hybrids developed by 6 x 6 diallel design excluding reciprocals, grown in Dharwad, Karnataka, India during 1999, revealed the predominance of non-additive gene effects for six of the ten characters studied (days to 50% flowering, fruit length, fruit diameter, pedicel length, pericarp thickness, number of seeds per fruit, green fruit weight, number of fruits per plant, green fruit yield per plant and resistance to leaf curl complex). Among the parents, the good general combiners were Pant C-1', 'KTPI-19' and 'RHRC-Cluster-Erect' for green fruit yield per plant, and 'RHRC-Cluster-Erect', 'Pant C-1' and 'PMR-52/88/K' for resistance to leaf curl complex. The superior crosses involved parents with low and high general combining ability effects, indicating that heterosis breeding will be appropriate for green fruit weight, green fruit yield per plant and leaf curl complex resistance.
