Декоративные персики – красивоцветущие деревья с цветками разных оттенков и сочетаний – от белого и нежно-розового до пурпурно-красного. Поскольку персик страдает от грибных инфекций, в селекционных программах часто используют в качестве донора устойчивости Prunus mira Koehne, который оказывает влияние и на другие признаки, в том числе на окраску цветков. Целью нашей работы было изучение состава флавоноидных пигментов в цветках родительских форм и новых сортов декоративного персика, полученных от скрещиваний с P. mira.</p></sec><sec><title>Объекты и методы</title><p>Объекты и методы. В исследование были включены четыре новых сорта селекции Никитского ботанического сада (НБС – ННЦ) и их родительские формы – P. mira и четыре сорта с морфотипом персика обыкновенного P. persica (L.) Batsch. Пигменты экстрагировали подкисленным этиловым спиртом из свежих лепестков и определяли методом ВЭЖХ.</p></sec><sec><title>Результаты</title><p>Результаты. В лепестках изученных объектов обнаружено 12 гликозидов цианидина и пеонидина в различных сочетаниях и 8 гликозидов кемпферола и кверцетина. В лепестках P. mira содержится наибольшее количество флавонолов (114 мг/г сухого вещества) и наименьшее – антоцианов (0,46 мг/г) среди окрашенных образцов. У сортов с пурпурно-красными лепестками преобладают антоцианы (15,6–16,0 мг/г). В лепестках гибридных пурпурно-розовых сортов накапливается значительно больше флавонолов (55–88 мг/г) и немного антоцианов (1,2–3,4 мг/г). Эта тенденция сохраняется у сортов от скрещивания с белоцветковым родителем. Заключение. Соотношение антоцианов и флавонолов в цветках персика определяет промежуточные окраски лепестков, полутона и зависит от видовой принадлежности растений. Включение P. mira в селекционные программы открывает возможности для создания сортов с новыми оттенками окраски цветка.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Ornamental peaches are flowering trees with petals ranging in color from white and pale pink to purplered. Because peach suffers from fungal infections, Prunus mira Koehne is often used in breeding programs as a donor of resistance. It also impacts on other traits, including flower color. The aim of this work was to study the composition of flavonoid pigments in the flowers of parent plants and new ornamental peach cultivars originated from P. mira.</p></sec><sec><title>Objects and methods</title><p>Objects and methods. Four new cultivars developed at the Nikita Botanical Gardens and their parental forms – P. mira and 4 cultivars with the P. persica morphotype – were included in the study. Pigments were extracted with acidified ethyl alcohol from fresh petals and identified by HPLC analysis.</p></sec><sec><title>Results</title><p>Results. Twelve glycosides of cyanidin and peonidin in different combinations and 8 glycosides of kaempferol and quercetin were found in the petal samples. Among colored plants, the highest amount of flavonols (114 mg g-1) and the lowest amount of anthocyanins (0.46 mg g-1) were found in P. mira petals. Anthocyanins predominate in cultivars with purple-red petals (16 mg g-1). Much more flavonols (55–88 mg g-1) and little anthocyanins (1.2–3.4 mg g-1) were accumulated in the purple-pink flowers of hybrid cultivars. This trend persisted in the cultivars from crosses with a white-flowered parent. Conclusion. The ratio of anthocyanins and flavonols in the peach flowers depends on the plant species and determines the petals’ intermediate colors and half-tones. Using P. mira in breeding programs provides opportunities for the development of cultivars with new shades of flower color.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>селекция</kwd><kwd>сорт</kwd><kwd>гибрид</kwd><kwd>антоцианы</kwd><kwd>флавонолы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breeding</kwd><kwd>cultivar</kwd><kwd>hybrid</kwd><kwd>anthocyanins</kwd><kwd>flavonols</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">Chandler S.F., Brugliera F.
