A diallel set of 6 parents and their 15 f1 hybrid were analyzed to understand the nature and magnitude of gene action and to identify the best combiners for yield and its components traits of chickpea (Cicer arietinum L.) the gca and sca components showed the predominance of additive gene action in governing days to flowering, days to poding. Plants height, number of pods, number of seeds/pod, plant biomass, harvest index, grain yield and 100 seed weight and non-additive gene action for number of branches. Estimates of gca effects shoed that the parents GL 98010 was the best general combiner, followed by GL 69010 and GL 90168. Thus the ascochyta blight resistant parents GL 96010 G 98010 and GL 901168 should be involved in the hybridization programmes for making yield breakthrough in chickpea. The cross combination GL 98010 x GL90168 showed significant and desirable sca effects for most of the traits including grain yield.
