The F1 and F2 progenies of a six –parent diallel cross (excluding reciprocals) of chickpea were analyzed for heterosis, combining ability and Inbreeding depression for quantitative and quality traits. The results indicated significant differences among the parents for general combining ability (gca) and crosses for specific combining ability (sca) for all the characters studied except number of grains per pod in F2’s. However, the sca component of variance was predominant indicating the predominance of non additive gene effects for the traits studied. Among the parents IPC-94-19, IPC-97-72 and MPJG-2000-108 were good general combiner for yield per plant and its attributing traits. IPC-94-94 was the best general combiner for protein content. Crosses KWR-108 X DCP-92-3, KWR 108XICP-97-72 and IPC-94-19 X IPC-94-94 were the best specific combiner for grain yield. The most specific cross for protein content was DCP-92-3 X MPJG2000-108. Three best F2’s which exhibited highest magnitude of positive sca effects for grain yield per plant were viz., IPC-94-19 x DCP-92-3, DCP-92-3x MPJG2000-108 and DCP-92-3 x IPC-94-94 . Estimates of inbreeding depression revealed that six F2’s showed significant negative inbreeding depression for grain yield. To ensure further increases in grain yield along with high protein content, combination of desirable yield components is advocated. The F1 hybrids showing high sca and parents having good gca will be included into chickpea improvement breeding programme for further improvement of grain yield in chickpea.
