The aim of our research was to estimate the heritability (h2,%) and genetic advantage (GA, %) of agro-morphological traits of winter barley hybrids forms (Strălucitor x Igri and Ciuluc x Igri) under different years conditions. Evaluation of genotypic variance components reveals high value of h2 (>60%) associated with high (>20%) and moderate GA, % (10-20%) for important traits (plant height, spike length, apical internode length, number of spikelets and ker-plant height, spike length, apical internode length, number of spikelets and ker-number of spikelets and ker-spikelets and kernel per spike, productive tillers per plant, thousand kernel weight) in the 8 productive two-rowed and four-rowed selected hybrids forms. This reflects additive effects in the inheritance of traits, a fact that allowed the efficient selection of interest forms with the potential for use in the further breeding work of winter barley.
