The nature and magnitude of genetic variances controlling biological yield and developmental traits viz., days to flowering, maturity period, plant height and branches per plant was worked out in F1 and F2 generations of a 5 x 5 half diallel in Chickpea. Both graphic and component analyses revealed overdominance with non-allelic interactions for biological yield, and branches per plant, while partial to complete dominance for days to maturity and complete to slightly overdominance for maturity period and plant height with predominance of additive gene effects was observed. Biparental mating in certain selected crosses has been suggested for exploiting the additive as well as non-additive gene effects simultaneously.
