Изучение генетического полиморфизма представителей Prunus pumila L. с широким диапазоном изменчивости морфологических признаков позволит выявить перспективные генотипы с высокой комбинационной способностью при их гибридизации.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включены 39 генотипов челябинской культурной популяции и 6 генотипов из Хакасии с крайними и промежуточными проявлениями признаков размера, окраски и формы плода, формы и структуры поверхности косточки, зазубренности края и формы листовой пластинки, габитуса растений и некоторых других. Генетические дистанции рассчитаны  с помощью  программы Past (Gower), используя матрицу бинарных состояний наличия или отсутствия  амплифицированных  фрагментов. UPGMA-дендрограмма построена с помощью TREECON (version 1.3b).</p><p>Результаты  и  заключение.  Отобранные 5 ISSR- и 2 RAPD-праймеры продемонстрировали свою эффективность  в выявлении  генетического  полиморфизма изученных  образцов.  Удалось  выявить  связь  отдельных  праймеров  с признаками  морфологии  косточек, формы листовой пластинки, габитуса растений и географического  происхождения  генотипа.  При  одновременном включении в анализ всех праймеров и генотипов кластерный анализ не смог сгруппировать клады для образцов P. pumila с наличием или отсутствием каких-либо признаков. Самостоятельная клада с достоверной бутстреп-поддержкой (100%) сформировалась только для генотипов систематически близкого вида P. tomentosa Thunb., взятых в анализ в качестве внешней группы. Причем внутри этой клады с достоверностью  бутстреп-поддержки 86% выявлены  различия между генотипами гибридного происхождения видов P. pumila × P. tomentosa (F3) и генотипом вида P. tomentosa. В селекционных целях на основе данных индексов генетического различия выявлены перспективные родительские пары для улучшения показателей качества плодов и типа кроны.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Studying genetic polymorphism of the Prunus pumila L. representatives with a wide range of variability in morphological characters will make it possible to identify promising genotypes with high combining ability for hybridization.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study covered 39 genotypes from the Chelyabinsk cultivated population and 6 genotypes from Khakassia, with extreme or intermediate expressions of such characters as fruit size, color and shape; stone shape and surface structure; leaf blade serration and shape; plant habitus, and some others. Genetic distances were calculated using the data matrix for binary states of presence (1) or absence (0) of amplified fragments with the Past Program (Gower). The UPGMA dendrograms were obtained in TREECON (version 1.3b).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The selected 5 ISSR and 2 RAPD primers demonstrated their effectiveness in detecting genetic polymorphism in the studied accessions. In individual cases, a weak connection of separate markers with leaf blade edge serration, stone surface structure, plant habitus, and geographic origin of the genotype was detected. Concurrent inclusion of all primers and genotypes in the cluster analysis failed to group the studied P. pumila samples into clades according to the presence/absence of any traits, which may attest to their close genetic affinity. An independent clade with reliable bootstrap support (100%) was formed only for the genotypes of the taxonomically close sp. P. tomentosa Thunb., analyzed as an external group. Moreover, this clade manifested (with the 86% reliability of bootstrap support) differences between the hybrid genotypes of P. pumila × P. tomentosa (F3) and the genotype of P. tomentosa. Parent pairs promising for fruit quality and shrub shape improvement through breeding were identified using the produced indices of genetic distinction.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>молекулярно-генетические  маркеры</kwd><kwd>морфологические признаки</kwd><kwd>ISSR-маркеры</kwd><kwd>RAPD-маркеры</kwd><kwd>кластеризация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molecular genetic markers</kwd><kwd>morphological  characters</kwd><kwd>ISSR markers</kwd><kwd>RAPD markers</kwd><kwd>clustering</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bortiri E., Oh S.H., Jiang J., Bagett S., Granger A., Weeks C. et al.
