Существенное снижение урожая ячменя может быть обусловлено мучнистой росой (возбудитель – Blumeria graminis (DC.) Golovin ex Speer f. sp. hordei Marchal). Подавляющее большинство сортов, допущенных к использованию на территории России, восприимчиво к патогену. Вовлечение в селекцию образцов, защищенных не использовавшимися ранее генами устойчивости, необходимо для обеспечения продовольственной безопасности страны. Довольно богатым источником пополнения банка эффективных генов устойчивости к патогену могут быть местные формы ячменя.</p></sec><sec><title>Материал и методика</title><p>Материал и методика. Изучали 950 образцов ячменя из Восточноазиатского центра происхождения и доместикации культурных растений: 449 образцов из Японии, 313 – Китая, 173 – Монголии, 15 – Непала. Эксперименты проводили в климатической камере при искусственном заражении ювенильных растений. Инокулюмом служила северо-западная (Санкт-Петербург, Пушкин) популяция B. graminis. Устойчивость оценивали с помощью балловой шкалы. Выделившиеся формы тестировали дважды.</p></sec><sec><title>Результаты и выводы</title><p>Результаты и выводы. Выявлена значительная изменчивость образцов коллекции ячменя из стран Восточной Азии по устойчивости к мучнистой росе. Симптомы болезни не обнаружены на растениях 16 изученных форм; слабое или умеренное развитие мицелия B. graminis отмечено на растениях 21 образца. Гетерогенны по изученному признаку 27 образцов ячменя. Различный уровень устойчивости выявлен у 64 изученных образцов (6,73%), среди которых 44 – сорта и селекционные линии, 20 – местные ячмени. Восприимчивы к северо-западной популяции патогена 93,27% образцов коллекции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. A significant reduction in the yield of barley may be provoked by powdery mildew (causative agent: Blumeria graminis (DC.) Golovin ex Speer f. sp. hordei Marchal). A vast majority of cultivars approved for use in Russia are susceptible to the pathogen. Including genotypes protected by previously unused resistance genes into breeding practice is necessary to ensure the national food security. Barley landraces could become a fairly rich source of replenishment for the bank of effective pathogen resistance genes.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study covered 950 barley accessions from the East Asian center of crop origin and domestication: 449 accessions from Japan, 313 from China, 173 from Mongolia, and 15 from Nepal. The experiments were carried out on young plants in a climatic chamber under artificial infection conditions. The northwestern (Pushkin, St. Petersburg) population of B. graminis served as an inoculum. Plant resistance was assessed using a scoring scale. The resistance of the selected forms was assessed twice.</p></sec><sec><title>Results and conclusions</title><p>Results and conclusions. Significant variability of barley accessions from the countries of East Asia in their resistance to powdery mildew was observed. Symptoms of the disease were not found on plants of 16 studied forms. Weak or moderate development of the B. graminis mycelium was recorded for 21 accessions. Twenty-seven accessions were heterogeneous in the studied trait. Various levels of resistance were identified in 64 studied accessions (6.73%), among which 44 represented cultivars and breeding lines, and 20 were landraces. The percentage of accessions susceptible to the studied population of the pathogen was 93.27%.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Hordeum vulgare</kwd><kwd>Восточная Азия</kwd><kwd>Blumeria graminis f. sp. hordei</kwd><kwd>степень поражения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hordeum vulgare</kwd><kwd>East Asia</kwd><kwd>Blumeria graminis f. sp. hordei</kwd><kwd>damage score</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование  выполнено  за  счет  гранта  Российского  научного  фонда  (Проект  № 21-76-00018, https://rscf.ru/project/21-76-00018/).
