The present study revealed the inadequacy of both additive- dominance and digenic epistatic models for all the traits except spikes/plant in majority of the crosses. Additive gene effects was prevailed over dominance gene effects for 100-grain weight and grains/spike, whereas reverse is for spikes/plant, grain yield/plant and biological yield. Digenic interactions and duplicate type of epistasis were also observed for these traits. Hybridization systems such as biparental mating and/or diallel selective matings could be useful for improvement of these traits.
