Клоновые подвои яблони – один из основных компонентов интенсивного садоводства. Степень поражения подвоя бактериальным ожогом влияет на устойчивость сорто-подвойной комбинации. Представлены исследования по маркированию локусов количественных признаков (QTL) устойчивости клоновых подвоев яблони к бактериальному ожогу плодовых культур (возбудитель Erwinia amylovora (Burrill.) Winslow et al.).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведен анализ коллекции из 20 форм подвоев. Для исследования были использованы SCAR-маркеры GE-8019 и AE10-375, а также микросателлитный маркер CH-F7-FB1.</p></sec><sec><title>Результаты</title><p>Результаты. Отмечен полиморфизм по всем трем маркерам, выявлены различные их сочетания в одном генотипе. Ранее отмечалось, что генотипы, которые несут все три маркера, более устойчивы, чем те, у которых они отсутствуют. Наличие всех трех маркеров отмечено только у форм 62-396 (В10), 16-1 и 2-9-12. У остальных генотипов не выявлен маркер GE-8019. Маркер АЕ10-375 идентифицирован у восьми клоновых подвоев. Микросателлитный маркер CH-F7-FB1 присутствует у всех исследуемых подвоев. Однако здесь отмечен полиморфизм. У большинства генотипов присутствует фрагмент 174 пн, но у двух из 20 форм выявлен фрагмент 210 пн. Клоновый подвой 70-20-21 является гетерозиготным по этому локусу. В анализируемой коллекции также отмечены образцы, имеющие только микросателлитный маркер: 70-20-21, G16, 2-12-10, 83-1-15, 54-118 (В118), «Малыш Будаговского», 71-7-22, 57-491, «Парадизка Будаговского» (В9), 70-20- 20 (В119), 76-3-6, 87-7-12. Изучение подвойных форм по признаку устойчивости к метаболитам возбудителя бактериального ожога проводили в лабораторных условиях с использованием культурального фильтрата E. amylovora на листовых эксплантах in vitro. У большинства изученных генотипов отмечены различные сочетания маркеров. Проведенные эксперименты показали, что у исследуемых форм с двумя маркерами из трех (АЕ10-375 и CH-F7-FB1) фенотипически проявлялся признак устойчивости к метаболитам E. amylovora. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Clonal apple rootstocks are one of the main components of intensive gardening. The degree of rootstock damage by fire blight affects the resistance of the variety–rootstock combination. The paper presents a study on marking quantitative trait loci (QTL) of resistance to fire blight Erwinia amylovora in clonal apple rootstock.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A collection of 20 rootstock forms was analyzed. For the study, SCAR markers GE-8019, AE10-375 and microsatellite marker CH-F7-FB1 were used.</p></sec><sec><title>Results</title><p>Results. Polymorphism was observed for all three markers, and their various combinations in one genotype were revealed. It was previously noted that genotypes that carry all three markers were more resistant than those that lack them. The presence of all three markers was observed only in forms 62-396 (В10), 16-1 and 2-9-102. The other genotypes did not have the GE8019 marker. The AE10-375 marker was identified in eight clonal rootstocks. Microsatellite marker CH-F7-FB1 was present in all tested rootstocks. However, polymorphism was detected there. Most genotypes had a 174 bp fragment, but a 210 bp fragment was identified in two of the 20 forms. Clonal rootstock 70-20-21 proved heterozygous for this marker. The analyzed collection also included samples that had only the microsatellite marker: G16, Malysh Budagovskogo, Paradizka Budagovskogo (B9), 54-118 (В118), 57-491, 70-20-20 (В119), 70-20-21, 71-7-22, 76-3-6, 83-1-15, 87-7-12, and 2-12-10. The study of rootstock forms on the basis of resistance to metabolites of the fire blight pathogen was carried out under laboratory conditions using the E. amylovora culture filtrate in vitro on leaf explants. Most of the studied genotypes had different combinations of markers. However, the experiments showed that forms 62-396 and 14-1 with two out of three markers (AE10-375 and CH-F7-FB1) phenotypically manifested the trait of resistance to metabolites of E. amylovora. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>яблоня</kwd><kwd>Erwinia amylovora</kwd><kwd>QTL</kwd><kwd>маркеропосредованная селекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>apple</kwd><kwd>fire blight</kwd><kwd>Erwinia amylovora</kwd><kwd>QTL</kwd><kwd>marker-assisted selection</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены в рамках Государственного задания Министерства сельского хозяйства РФ на 2020 г. по теме: «Селекция зимостойких слаборослых клоновых подвоев яблони с использованием молекулярных маркеров и культуры соматических тканей in vitro» (№ ААААА20-120011690041-9) на базе Центра коллективного пользования «Селекция сельскохозяйственных культур и технологии производства, хранения и переработки продуктов питания функционального и лечебно-профилактического назначения» Мичуринского государственного аграрного университета.</funding-statement><funding-statement xml:lang="en">The studies were carried out in the framework of the State Task of the Ministry of Agriculture of the Russian Federation for 2020 on the topic: “Selection of winter-hardy dwarf apple clonal rootstocks using molecular markers and somatic tissue culture in vitro” (No. АААА-А20-120011690041-9) at the Center for Collective Use “Crop breeding and production technology, storage and processing of food products for functional and therapeutic purposes” of Michurinsk State Agrarian University.</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">Akomolafe G.F., Paul T.T., Ubhenin A., Abok J.
