Обыкновенная злаковая тля Sсhizaphis graminum Rondani способна существенно снизить урожайность ячменя и других злаковых культур в южных регионах России. Вредоносность фитофага может лимитировать возделывание устойчивых сортов. В то же время характерное для S. graminum специфическое взаимодействие с генотипами растения-хозяина определяет необходимость постоянного поиска новых доноров устойчивости для расширения генетического разнообразия сортов ячменя. </p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В лабораторных экспериментах изучили устойчивость 178 образцов местного ячменя из Узбекистана к краснодарской популяции насекомого. Ювенильные растения заселяли разновозрастными тлями и при гибели восприимчивого контроля (сорт ‘Белогорский’) оценивали устойчивость по шкале от 0 до 10 (гибель растений). К классу устойчивых относили растения с баллами 1–4 (повреждено до 30% листовой поверхности), поврежденность 5–8 баллов свидетельствовала об умеренной устойчивости растений, 9–10 – о восприимчивости. Кроме того, оценили поврежденность тлей сорта озимого ячменя ‘Post’, который защищен идентифицированным ранее геном устойчивости Rsg1. </p></sec><sec><title>Результаты и выводы</title><p>Результаты и выводы. Выделили 52 гетерогенных по изученному признаку образцов ячменя. У шести образцов выявлены растения с высокой (3–4 балла) и умеренной (5–8 баллов) устойчивостью, 6 образцов дифференцированы на 3 фенотипических класса: устойчивый, умеренно устойчивый, восприимчивый, а у 40 образцов проявление устойчивого компонента варьировало в пределах 5–7 баллов (повреждено от 31 до 60% листовой поверхности). Отчетливо выраженная устойчивость 12 образцов контролируется аллелями геноустойчивости, отличающимися от Rsg1. После отбора по устойчивости выделившиеся образцы могут быть использованы в селекции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The greenbug (Sсhizaphis graminum Rondani) can significantly reduce the yield of barley and other cereals in the southern regions of Russia. Cultivation of resistant varieties can significantly limit the pathogen’s harmfulness. At the same time, specific interaction with the genotypes of the host plant, characteristic of S. graminum, requires a continuous search for new resistance donors to broaden the genetic diversity of barley cultivars. </p></sec><sec><title>Materials and methods</title><p>Materials and methods. The resistance of 178 accessions of barley landraces from Uzbekistan to the Krasnodar greenbug population was tested in laboratory experiments. Juvenile plants were infested with aphids of different ages, and when the susceptible control died (cv. ‘Belogorsky’), resistance was assessed on a 0 to 10 (plant death) rating scale. Plants with a damage rate of 1–4 points (up to 30% of the leaf surface being damaged) belonged to the resistant class; damage rate of 5–8 points indicated moderate resistance of plants, and that of 9–10 meant susceptibility. In addition, we assessed the aphid damage of the winter barley cultivar ‘Post’, protected by the previously identified resistance gene Rsg1.</p></sec><sec><title>Results and conclusions</title><p>Results and conclusions. We identified 52 barley accessions as heterogeneous for the studied trait. In six accessions, plants with high (points 3 to 4) and moderate (5 to 8) resistance were identified; 6 accessions were differentiated into 3 phenotypic classes: resistant, moderately resistant, and susceptible; and in 40 accessions the manifestation of the resistance component varied within 5 to 7 points (from 31 to 60% of the leaf surface being damaged). The distinctly expressed resistance of 12 accessions is controlled by alleles of resistance genes that differ from Rsg1. After selection for resistance, the identified accessions can be used in breeding.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Hordeum vulgare L.</kwd><kwd>Schizaphis graminum Rondani</kwd><kwd>гены устойчивости</kwd><kwd>селекция растений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hordeum vulgare L.</kwd><kwd>Schizaphis graminum Rondani</kwd><kwd>genes for resistance</kwd><kwd>plant breeding</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке РФФИ (грант  № 20-016-00048) и в рамках государственного задания согласно тематическому плану ВИР № 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-statement xml:lang="en">The research was supported by the Russian Foundation for  Basic Research (Grant No. 20-016-00048) and 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">An stead J.A., Burd J.D., Shufran K.A.
