In five crosses, viz., JG-315 X JG-74, JG-315 x Vishwas, JG-315 X Vikas, JG-315 X JG-62 and JG-315 x Scl. 436 of chickpea (Cicer arietinum L.), scaling test with five generation means showed the involvement of epistatic gene action in the expression of fruiting branches/plant, pods/plant, 100-grain weight, yield/plant, and days to maturity, except for fruiting branches and pods/plant in the crosses JG-315 x Vishwas and JG-315 x JG-62, and for days to maturity in JG-315 x Sel. 436. In all the five crosses, dominance gene action was involved for all the characters except for 100-grain weight. In 4 out of 5 crosses, additive gene action was involved in the inheritance of 100-grain weight. But additive and dominance gene effects, dominance x dominance, and additive x additive interactions were important for all the components. Dominance effects, followed by interactions and additive component played a significant role in the inheritance of grain yield. Duplicate epistasis was mare predominant.
