Способность плодов яблони сохранять свои потребительские качества длительный период является одним из важных показателей сорта. Значительную роль при хранении плодов играет количество вырабатываемого в них этилена. В работе представлены результаты идентификации генов, вовлеченных в контроль биосинтеза этилена у сортов яблони селекции Свердловской селекционной станции садоводства. Всего проанализирован 21 сорт яблони. Основной задачей исследования было обнаружение аллелей Md-ACO1-1 и Md-ACS1-2 в гомозиготном состоянии. Сочетание этих аллелей в одном генотипе снижает выработку этилена в плодах, что способствует их длительной лежкости. Проведенный анализ показал наличие полиморфизма по двум исследуемым генам. Для гена Md-ACO1 характерно наличие двух аллелей у большинства сортов. Аллель Md-ACO1-1 в гомозиготном состоянии идентифицирован у сорта Исетское позднее. Анализ гена Md-ACS1 выявил преобладание аллельной формы Md-ACS1-1. Аллельная форма Md-ACS1-2 отмечена только у гетерозиготных образцов. Сочетание аллелей Md-ACO1-1 и Md-ACS1-2 в гомозиготном состоянии не обнаружено. Однако для селекционной работы представляют интерес и гетерозиготные формы. Они могут служить генисточником признака сниженного биосинтеза этилена при создании сортов с длительным сроком хранения. Такими сортами являются Сокол ясный, Аксена, Розоватое зимнее, Свердловчанин, Исетское позднее и Благая весть. Проведено сравнение сроков хранения плодов и генотипа сорта. Аллели, ассоциированные со сниженным уровнем биосинтеза этилена, характерны как для сортов с низкой, так и для сортов с высокой степенью лежкости.</p></abstract><trans-abstract xml:lang="en"><p>One of the directions of apple breeding in the Middle Urals is the development of varieties with a long-term storability. The ability of apples to maintain their consumer qualities for a long period is one of the most important indicators of the variety. A significant role in the storage of apples is played by the amount of ethylene produced in them. The paper presents the results of identification of genes involved in the control of ethylene biosynthesis in apple varieties selected by the Sverdlovsk horticultural breeding station. A total of 21 apple varieties were analyzed. The main objective of the study was to detect Md-ACO1-1 and Md-ACS1-2 alleles in the homozygous state. The combination of these alleles in one genotype reduces the production of ethylene in fruits, which contributes to their long-term storability. The analysis showed the availability of polymorphism in the two studied genes. The Md-ACO1 gene is characterized by the availability of two alleles in most varieties. The homozygous Md-ACO1-1 allele was identified in the Isetskoe pozdnee variety. Analysis of the Md-ACS1 gene revealed the predominance of the Md-ACS1-1 allele form. The Md-ACS1-2 allelic form was observed only in heterozygous samples. No combination of Md-ACO1-1 and Md-ACS1-2 alleles was found in the homozygous state. However, heterozygous forms are also of interest for breeding. They can serve as a source of a character of reduced ethylene biosynthesis when creating varieties with a long-term storability. Such varieties are Sokol yasnyy, Aksena, Rozovatoe zimnee, Sverdlovchanin, Isetskoe pozdnee, Blagaya vest'. The comparison of fruit storage periods and the genotype of the variety has been made. Allelesassociated with a reduced level of ethylene biosynthesis are typical both for the varieties with low and high storability.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гены синтеза этилена Md-ACO и Md-ACS</kwd><kwd>лежкость плодов</kwd><kwd>садоводство Среднего Урала</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Md-ACO and Md-ACS ethylene synthesis genes</kwd><kwd>storability of fruits</kwd><kwd>horticulture of the Middle Urals</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках направления 150 Программы ФНИ государственных академий наук на 2013-2020 гг. по теме «Разработка и совершенствование методов селекционной работы, создание исходного материала и адаптивных сортов зерновых, зернобобовых, кормовых, плодово-ягодных, декоративных культур и картофеля» (№0773-2019-0022) и проекта № 0662-2019-0004 «Коллекции вегетативно размножаемых культур (картофель, плодовые, ягодные, декоративные, виноград) и их диких родичей ВИР – изучение и рациональное использование».</funding-statement><funding-statement xml:lang="en">The research was performed within the framework of Direction 150 of the Program of the Basic Research Institute of State Academies of Sciences for 2013-2020 on the topic «Development and improvement of breeding methods, creation of source material and adaptive varieties of cereals, legumes, fodder, fruit and berry, ornamental crops and potatoes» (No. 0773-2019-0022), Project No. 0662-2019-0004 «Collections of Vegetatively Propagated Crops (Potato, Fruit, Berry and Ornamental Crops, Grapes) and Their Wild Relatives at VIR: Studying and Sustainable Utilization».</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">Котов Л.
