Диагностическими признаками для различения видов считаются наличие и типы трихом узлов стебля (УС) и нижних цветковых чешуй (НЦЧ), а также экологические условия произрастания. В Приморском крае и Республике Алтай нами обнаружен ряд смешанных популяций, в которых существует визуально непрерывная изменчивость по типу трихом НЦЧ: от голых и гладких до длинноволосистых. Кроме того, в Приморском крае найден ряд популяций, в которых совместно произрастают особи как с гладкими, так и с волосистыми УС. Изучен полиморфизм ISSR-маркеров среди выборочных образцов трех видов из разных точек ареала вместе с реперными видами E. ciliaris и E. gmelinii. Консенсусная дендрограмма, построенная по результатам использования ISSR-маркеров, показала отсутствие видовой специфичности у образцов подсекции Pendulini. Созданы гибриды между особями разных видов подсекции в шести комбинациях скрещиваний. У всех растений F1 были нормально развитые открытые пыльники, семенная фертильность в разных комбинациях составляла от 8 до 89 %. В выборках F2 отсутствовали стерильные особи и наблюдалось увеличение семенной фертильности до нормальных значений. Следовательно, три таксона формируют единый рекомбинационный генпул. Выявлено, что диагностические признаки контролируются одной парой аллелей по опушению УС и одной или двумя парами аллелей (в различных комбинациях скрещивания) по опушению НЦЧ. Данные признаки представляют собой нормальное проявление внутривидовой изменчивости. Предложено рассматривать виды E. brachypodioides и E. vernicosus в качестве внутривидовых таксонов E. pendulinus s. l. в ранге разновидностей.</p></abstract><trans-abstract xml:lang="en"><p>Currently three species are recognized in Russia within the genus Elymus subsection Pendulini, namely, E. pendulinus, E. brachypodioides and E. vernicosus. The degree and quality of lemma and stem node vestitures and ecology are considered important characters for species delineation. In Primorsky krai and Altai Republic we have found a number of mixed populations in which there is visually continuous variation in lemmas vestitures from being completely glabrous to densely puberulent or pilose. Additionally, there are a number of populations in Primorsky krai in which individuals having either smooth or pilous stem nodes grow together. A study of polymorphism of ISSR markers among selective accessions of three species from different locations was carried out together with the reference species E. ciliaris and E. gmelinii. The consensus dendrogramm constructed by results of ISSR markers has shown no taxon specific patterns in accessions of the subsection Pendulini. Hybrids between the individuals of different species of the subsection in six cross combinations have been created. All F1 plants had normally developed open anthers, seed fertility (SF) ranged from 8 % to 89 % in different combinations. In F2 populations no sterile individuals or increase of SF up to normal values were observed. Hence, three taxa form a unified recombination gene pool. The diagnostic characters were found to be controlled by one pair of alternative alleles for glabrous vs. hairy stem nodes, and by one or two pairs of alleles in different cross combinations for glabrous vs. hairy lemmas. These characters can be considered as normal inter- and/or intra-population variation. Therefore, E. brachypodioides and E. vernicosus need to be relegated to infraspecific rank within Elymus pendulinus s. l. as varieties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Elymus</kwd><kwd>таксономия</kwd><kwd>диагностические признаки</kwd><kwd>ISSR-маркеры</kwd><kwd>гибридизация</kwd><kwd>семенная фертильность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Elymus</kwd><kwd>taxonomy</kwd><kwd>diagnostic features</kwd><kwd>ISSR markers</kwd><kwd>hybridization</kwd><kwd>seed fertility</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Российский фонд фундаментальных исследований, Cand.
