The paper presents the results of many years of research on the selection of hulless barley in the Middle Volga region. For the first time in the region, purposeful breeding of hulless barley is carried out according to the complete scheme of the breeding process. Sources and donors of several biological and economically valuable traits and properties have been identified from the world collection of hulless barley, including accessions with a set of indicators: k-21694 (Russia, Sverdlovsk region), k-28017, k-28076, k-28091 (Mexico), k-29189 (Canada), k-30919 (Russia, Omsk region). The basic principles of breeding work to improve the crop of hulless barley have been developed. The possibility of creating hulless barley forms with a sufficient level of adaptability and productivity for specific soil and climatic conditions is shown. A new source material for breeding has been created in the form of hybrid populations and breeding lines. Designed lines „813 nud‟ and „19471 nud‟ have been proposed for use in breeding programs for hulless barley for grain fodder and food purposes for the yield and increase in the protein content in the grain. At the last stage of research, a number of promising varieties of barley were created with a grain yield potential of up to 5 t/ha and higher, a protein content in the grain of 15–17%, with a high thousand-kernel weight, test weight and uniformity of grain, which are competitive in relation to hulled varieties during cultivation in the conditions of the forest-steppe zone of the Middle Volga region. Further directions and methodological approaches in the breeding of hulless barley have been established.
