Evaluation of the initial material for fineness, precocity and productivity to create varieties of spring barley in the conditions of the Middle Volga region

The article presents the results of the study of the collection of varieties of spring barley, represented by samples from research institutes of Russia, countries of the far and near abroad. A brief description of the agro-climatic conditions of the research is given. The results of evaluation of collection samples of barley on productivity, fineness and precocity are presented. The assessment of vegetation period samples was carried out. Assessment of precocity was carried out on the period of shoots - earing. According to the results of the analysis, samples were selected for use as sources of precocity, with the duration of the period «shoots-earing» 35-37 days: Submedikum 1958/01, Grif, Omskiy 96, Biom, Vadim, Oskar, Spomin. From samples of the collection nursery on the greatest weight of 1000 grains new lines of selection Volga region research institute of selection and seed farming were allocated - Nutans 2054/02, Submedikum 2149/01 (Povolzhskiy 49), Submedikum 2149/17, variety Agat, as well as samples of T-12, Anna, Orenburgskiy 15, Orenburgskiy 17 from the Orenburg region, Omskiy 90, Omskiy 96 from the Omsk region, Medikum 11, Medikum 125, Medikum 176 from Kazakhstan, variety Khago from Belarus, Vzirets from Ukraine, variety KVS Tessa from Germany, Eksployer and Pioner varieties from France, Evergrin and Chiraz from Denmark, which it is advisable to use as sources of fineness. The highest grain yield marked varieties selection Volga region research institute of selection and seed farming - Vityaz', Povolzhskiy 16, Submedikum 2149/02, Samara NIISKH - Grif, Krasnokutskoy s.o.s. Nutans 553, Krasnoyarsk NIISKH - Buyan, Ukraine - Bad'oriy, France - Yeyfel', which can be used as source material as sources of productivity. As a result of the conducted researches sources of spring barley on economically valuable signs for their use in selection programs are allocated.
