Six generations (P₁, P₂, F₁, F₂, BC₁ and BC₂) of three barley crosses were used for computation of generation mean analysis under normal and saline sodic soil conditions for yield contributing traits.  In general, magnitude of dominance effect (h) has a greater value than additive effect (d) in all the traits. It is obvious that non-fixable gene effects (h), (j) and (l) were higher than the fixable (d) (i) in all the crosses in all the characters, indicating greater role of non-additive effects in the inheritance of all the characters. Both additive (d) and dominance (h) gene effects were important for all the traits. It is obvious that non-fixable gene effects (h) (j) and (l) were higher than the fixable (d) (i) in all the crosses for all the characters, indicating greater role of non-additive effects in the inheritance of all the characters studied.
