In this article, the authors pay special attention to the study of the source material of barley for economically valuable characteristics, including the creation of high-protein forms for breeding. In this case, not only the data on field experiments are reflected, but also the biochemical analysis of grain and the calculation of the gross protein harvest. The data are shown in the article on research conducted in the period 2019–2023 at the experimental field of Northern Trans-Ural State Agricultural University for the study of collectible barley varieties in order to identify sources of high protein content of grain and use them in breeding programs. It was found that the isolated sources of high protein content of Vulkan, Kedr, Simon, Luka, Nudum 95, Etienne accumulated protein of 13.5–15.3%, which is 2.2–4.0% higher than the standard Abalak variety. The gross protein harvest was 606.1–689.1 g/m2, which is 103.3–186.3 g/m2 higher than the standard. Isolated sources with a high protein content in grain are included in crosses with widespread registered varieties Acha and Abalak, not only in the Tyumen region but throughout Russia. The obtained source material is studied according to the classical scheme of the breeding process. Sources of high protein content are included in the breeding nursery and ecological study in the natural and climatic zones of Tyumen region.
