The study was conducted to get genetic information on quantitative characters of F₁in barley through diallel crosses using seven malting barley. The results obtained were summarized as follows. Additive, dominant, maternal, and reciprocal effect were observed in culm length, spike length, awn length, culm diameter, grain length, grain width, number of grains per spike, and 1000 grain weight. Based on the Vr-Wr graphical analysis, culm length, spike length, awn length, grain length, and number of grains per spike were found to be inherited over dominance. Dominant effects were higher than additive effects in culm length, spike length, awn length, culm diameter, grain length, grain width, number of grains per spike, and 1000 grain weight. The narrow- sense heritability showed high value as 40.06% for spike length.
