Abstract: Background. Omsk Agrarian Scientific Center is a comprehensive scientific institution that carries out research in promising areas in the field of agricultural production. When creating varieties with the given parameters, it is important for the breeder to choose the right parental forms, in connection with which each breeding laboratory maintains a collection of samples - both local and foreign and foreign selection. Purpose: to assess the significance of samples of the collection nursery for the creation of barley varieties (Hordeum vulgare L.) in the Omsk Agrarian Scientific Center. Materials and methods. The object of research was the barley varieties of the VIR collection, various breeding centers. Genetic passports for the alleles of hordeincoding loci in barley varieties are presented on the official website of the Russian Academy of Sciences Vavilov Institute of General Genetics. Results. The barley varieties of the collection nursery are mainly represented by monomorphic varieties; the standard variety Omskiy 95 (Hrd A281 B1+8 F1+2) and Taler (Hrd A18 B21+67 F1+2) are heterogeneous. The difference of varieties by biotypes was not reflected in the difference in their productivity and grain quality. The varieties of the collection nursery were mainly characterized by reduced productivity and grain quality in the conditions of the southern forest-steppe of Western Siberia. Conclusion. According to the complex of characteristics of productivity and quality of grain, varieties were selected that are recommended for further research: Aley, Khadzhibey, Taler, Olenyok, Abalak, Emelya, Isabella. The cultivars of the collection nursery Odessa 100 and Donetsk 8 are the parent varieties of the Omsk Agrarian Scientific Center cultivars, Omsk 91, Omskiy golozerniy 2 and Sasha, which have become widespread. The relatedness of these cultivars in terms of gliadin spectra was revealed. EDN: NGJWGO
