Genetic component of variances were estimated for ten characters in a 10 x 10 dialiel fashion over three environments. The findings reveled that both additive (D) and non-additive (H1 & H2) components of variation were important for ali the characters. However, the relative magnitude of dominance component was higher than additive component i.e. prevalence of non-additive gane effects and over dominance suggested that on or the other form of biparental and/or recurrent selection procedures and dialiel selective mating might give fruitful results for improving the grain yield in six rowed barley.
