In order to estimate additive and dominance components of genetic variance and detection of non-allelic interaction for the salt tolerance criteria in barley, 7 generations (P1, P2, F1, F2, F3, BC1, BC2) derived from the cross Wiesel burger/AborxLokus/Bda and the check were used in a split plot design with two replications in hydroponic culture. Significant differences were found between both salinity levels and genotypes for all the characters investigated. Mean generation analysis indicated the involvement of additive, dominance and epistatic type of gene action in the inheritance of leaf weight (additive, dominance and epistasis), biomass (additive and epistasis), K+, Na+ and K+/Na+ (dominance and epistasis). Heritability estimate was low for K+ and Na+, moderate for shoot length, leaf weight, biomass and K+/Na+ and high for root length. Over dominance type of gene action was found for shoot length, biomass, K+, Na+ and K+/Na+, while partial dominance for root length and leaf weight.
