В 2020 г. в Госреестре РФ зарегистрировано 47 гибридов и 8 сортов брокколи, среди них 14 сортов и гибридов российской селекции. Необходимость совершенствования сортимента по целому ряду актуальных направлений селекции требует привлечения новых эффективных методов, в том числе методов маркер-вспомогательной селекции и ассоциативного картирования. Оценка коллекции брокколи ВИР с использованием молекулярно-генетических маркеров позволит предоставить новый исходный материал для селекции улучшенных сортов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено молекулярно-генетическое исследование 39 сортов и гибридных популяций брокколи различного географического происхождения, отличающихся по биологическим особенностям и направлениям использования. Для анализа были отобраны 35 маркеров микросателлитных последовательностей, специфичных для генома Brassica L.</p></sec><sec><title>Результаты и заключение</title><p>Результаты и заключение. С помощью использованных праймеров идентифицировано 110 полиморфных фрагментов. В изученных локусах идентифицировано от трех до семи аллелей. Показатель дискриминационной силы маркеров варьировал от 0,75 до 0,96 и в среднем составил 0,91, среднее число фрагментов на маркер – 4,4. У исследованных образцов выявлено 10 уникальных и 12 редких (встречающихся менее чему 8% образцов) аллелей. В то же время аллель локуса BC65 длиной 201 пн обнаружен у 95% образцов, то есть был практически общим. Все использованные маркеры имеют достаточно высокую диагностическую ценность для анализа генетического полиморфизма и могут быть использованы для ДНК-идентификации сортов брокколи. Анализ генетического сходства коллекционных образцов, выполненный методом Unweighted Neighbor-Joining в программе DarWin, позволил выявить четыре близкородственных кластера в изученной выборке генотипов. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Broccoli is an early-ripening vegetable crop that contains many biologically active compounds and mineral elements. According to the Genesys database, the global genebank collections contain no more than 465 different broccoli accessions. Fourteen cultivars and hybrids developed in Russia are registered in the State Register of the Russian Federation. The need to improve the assortment in a number of important breeding target areas (small habitus, non-spawning, bud size, disease resistance, etc.) requires the use of new effective techniques, including marker-assisted selection methods and association mapping. In this regard, it seems relevant to evaluate the VIR collection of broccoli using molecular genetic markers, which will provide new source material for breeding.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A molecular genetic study involved 39 broccoli cultivars and hybrid populations of different geographical origin, with various biological characteristics, and for various uses. For the analysis, 35 markers of microsatellite sequences specific to the Brassica L. genome were selected. PCR products were separated by electrophoresis on a 3% agarose gel.</p></sec><sec><title>Results and conclusions</title><p>Results and conclusions. As a result, 110 polymorphic fragments were identified. In the studied loci, 3 to 7 alleles were pinpointed. The discriminating power of markers ranged from 0.75 to 0.96, and averaged 0.91; the average number of fragments per marker was 4.4. Ten unique alleles and 12 rare alleles (found in less than 8% of the samples) were observed in the studied accessions. On the other hand, the 201 bp allele of the locus BC65 was found in 95% of accessions, that is, it was almost common. All used markers have a sufficiently high diagnostic value and can be recommended for DNA identification in broccoli cultivars. An analysis of the genetic similarity of the collection accessions, carried out in the DarWin program using the Unweighted Neighbor-Joining method, made it possible to establish four closely related clusters. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>SSR-маркеры</kwd><kwd>генетическое разнообразие</kwd><kwd>ДНК-идентификация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>SSR markers</kwd><kwd>genetic diversity</kwd><kwd>DNA identification</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">Amiryousefi A., Hyvönen J., Poczai P. iMEC: Online Marker Efficiency Calculator.
