Наиболее эффективный способ защиты  урожая  сельскохозяйственных  культур  от  болезней – возделывание устойчивых сортов. Гидротермический режим южно-плоскостной зоны Дагестана благоприятствует поражению растений ячменя возбудителем мучнистой росы. Наблюдаемый ежегодно высокий уровень развития болезни позволяет достоверно оценить устойчивость коллекционных образцов к патогену.</p></sec><sec><title>Материал и методика</title><p>Материал и методика. Материалом для исследований служил 1361 образец ячменя (570 – селекционные сорта, 791 – образцы местного ячменя) разного эколого-географического происхождения и типа развития. Полевые опыты закладывали в один срок при озимом посеве. Устойчивость растений к мучнистой росе оценивали  в период  колошения  и в фазу молочной  спелости зерна  с помощью  балловой  шкалы.  Каждый  образец изучали не менее трех лет.</p></sec><sec><title>Результаты и выводы</title><p>Результаты и выводы.  Результаты многолетнего изучения ячменя  культурного свидетельствуют о существенной внутривидовой изменчивости коллекционных образцов по устойчивости к патогену. Значительная часть исследованного материала (63,1%) восприимчива к мучнистой росе. Частота устойчивых к болезни образцов составляет 11,0%, среднеустойчивых – 25,9%. Среди местных ячменей выявлено четыре устойчивых образца из Абиссинского, Переднеазиатского и Средиземноморского центров происхождения культуры. Для использования в селекции на иммунитет рекомендуются 17 сортов (преимущественно из стран Западной Европы), характеризующихся высоким уровнем устойчивости к дагестанской популяции возбудителя мучнистой росы.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The most effective way of protecting crops from diseases and pests is the breeding and cultivation of resistant varieties. The hydrothermal regime in the southern plains of Dagestan favors damage to barley plants by the causative agent of powdery mildew. The high level of disease progress observed annually helps to reliably assess the resistance of collection accessions to the pathogen.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The research material included 1361 barley accessions (570 improved cultivars and 791 landraces) of different ecogeographic origin and growth habit. Field experiments were launched concurrently with winter sowing. Powdery mildew resistance was scored during the heading period and in the milk ripeness phase using a point scale. Each accession was assessed for at least three years.</p></sec><sec><title>Results and conclusions</title><p>Results and conclusions. The results of a long-term study disclosed a significant intraspecific variability of barley collection accessions in their resistance to powdery mildew. A significant part of the studied barley accessions (63.1%) appeared susceptible to the pathogen. The occurrence frequency of disease-resistant accessions was 11.0%, while those with medium resistance reached 25.9%. Among the landraces, four resistant accessions from the Abyssinian, West Asian and Mediterranean centers of crop origin were identified. Seventeen barley varieties resistant to powdery mildew (predominantly originated from Western Europe) are recommended for use in breeding for immunity.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Hordeum  vulgare L</kwd><kwd>Blumeria graminis f. sp. hordei</kwd><kwd>резистентность</kwd><kwd>селекция растений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hordeum vulgare L</kwd><kwd>Blumeria graminis f. sp. hordei</kwd><kwd>resistance</kwd><kwd>plant breeding</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа  выполнена  в рамках  государственного  задания  согласно  тематическому  плану  ВИР  по  проекту №0662-2019-0006  «Поиск,  поддержание  жизнеспособности и раскрытие потенциала наследственной изменчивости мировой коллекции зерновых и крупяных культур ВИР для развития оптимизированного генбанка и рационального использования в селекции и растениеводстве».</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was performed within the framework of the State Task according to the theme plan of VIR, Project No. 0662-2019-0006 “Search for and viability maintenance, and disclosing the potential of hereditary variation in the global collection of cereal and groat crops at VIR for the development of an optimized genebank and its sustainable utilization in plant breeding and crop production”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abdullaev R.A., Lebedeva T.V., Alpatieva N.V., Yakovleva O.V., Kovaleva O.N., Radchenko E.E., Anisimova I.N., Batasheva B.A., Karabitsina Yu.I., Kuznetsova E.B.
