The main objective of this work is to follow the behavior of varieties and hybrids of autumn barley under the influence of the biological, technological factor. The varieties of barley taken into cultivation are the following: Idyllic, Jup; Melia; SU Ellen; Azrah and Dakota The productive performance of the analyzed barley varieties varied significantly, highlighting a clear influence of genetic potential on yield under local pedoclimatic conditions. The Jup variety has demonstrated obvious superiority, registering the highest production and high statistical significance, which recommends it as an optimal choice for cultivation in the area. Protein content varied between varieties, with no direct correlation between production level and protein quality always observed. This variation suggests that the selection for yield must be balanced with the selection for quality, depending on the final destination of the production (feed, industrial, food). The hectoliter mass, an indicator of commercial quality, recorded good values for most varieties, but the differences between them were statistically significant only in some cases. Varieties with a high hectoliter mass can have a competitive advantage when it comes to recovery. All varieties analysed demonstrated a significant advantage over the Dakota control in terms of ear length, number of spikes and grains per ear, as well as grain weight.
