Современное производство семян подсолнечника основано на возделывании высокопродуктивных гетерозисных гибридов F1 от скрещиваний линий с цитоплазматической мужской стерильностью (ЦМС) РЕТ1-типа и линий-восстановителей фертильности пыльцы. Донором функционального аллеля ядерного гена Rf1, ответственного за восстановление фертильности пыльцы растений F1, служит отцовская линия. Выявление носителей рецессивных и доминантных аллелей локуса Rf1 с помощью диагностических молекулярных маркеров позволяет ускорить процесс селекции материнских и отцовских родительских линий для создания гибридов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Материалом для исследования служили 75 линий генетической коллекции подсолнечника ВИР различного происхождения, а также гибриды от скрещиваний стерильной линии ВИР 116А с фертильными линиями, различавшимися по типу цитоплазмы (фертильный или стерильный) и наличию молекулярных маркеров, большинство которых сцеплены с локусом Rf1. Для валидации маркеров использовали два подхода: 1) анализ ассоциаций между способностью линии к восстановлению фертильности пыльцы, либо к закреплению стерильности, и присутствием в генотипе молекулярных маркеров, а также 2) оценку частоты рекомбинации между локусом Rf1 и маркерными локусами в четырех расщепляющихся гибридных популяциях F2.</p></sec><sec><title>Результаты</title><p>Результаты. Ни один из маркеров не показал 100% эффективности при анализе изученной выборки генотипов. Чаще всего, среди линий, предположительно несущих доминантный аллель Rf1, отмечался маркер ORS511. Показатели фертильности пыльцы гибридов F1 от межлинейных скрещиваний составили 89–99%. Расщепление растений F2 по признаку фертильность/стерильность пыльцы было близко к теоретически ожидаемому 3:1 при моногенном контроле признака. Маркеры HRG01, HRG02, ORS511 наследовались сцепленно с признаком восстановления фертильности, при этом частота рекомбинации между локусом Rf1 и маркерами различалась в разных комбинациях скрещиваний. По данным анализа гибридов ВИР 116А × ВИР 740 и ВИР 116А × RIL 130, среди изученных маркерных локусов ближе всех к локусу Rf1 расположен маркер ORS511 (2,2 и 3,3%, соответственно). В скрещивании ВИР 116А × ВИР 210 частота рекомбинации между локусами Rf1 и ORS511 составила 7,5%, а в комбинации ВИР116 × ВИР195 –8,9%.</p></sec><sec><title>Заключение</title><p>Заключение. Для идентификации аллелей гена Rf1 в коллекции генетических ресурсов подсолнечника и для маркер-опосредованного отбора в расщепляющихся гибридных популяциях, полученных с участием линий генетической коллекции ВИР, наиболее эффективны маркеры ORS511, HRG01 и HRG02.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Modern production of sunflower seeds is currently based on the cultivation of high-yielding heterotic F1 hybrids from crossbreeding of lines with cytoplasmic male sterility (CMS) of PET1-type and fertility restorer lines. The paternal parent serves as a donor of the nuclear Rf1 gene functional allele, which is responsible for pollen fertility restoration in F1 plants. The detection of carriers of the Rf1 locus recessive and dominant alleles using diagnostic molecular markers accelerates breeding of female and male parental lines for creating hybrids.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The material for the study included 75 lines of various origins from the VIR sunflower genetic collection as well as hybrids from crosses of VIR 116A sterile line with fertile lines differing in the type of cytoplasm (fertile or sterile) and the presence of molecular markers, most of which were linked to the Rf1 locus. For marker validation, two different approaches were used: either by analyzing associations between the ability of a line to restore pollen fertility and the presence of molecular markers in its genotype, or by estimating recombination frequency between the Rf1 locus and marker loci in four segregating hybrid populations.</p></sec><sec><title>Results</title><p>Results. According to the obtained results, no markers demonstrated 100% efficiency in the analysis of the sample of genotypes. The ORS511 marker was most frequently observed among the lines presumably carrying the dominant allele Rf1. Pollen fertility of F1 hybrids from interline crossings was 89-99%. The segregation for fertility/sterility in F2 fitted the theoretical ratio of 3:1 expected in case of the monogenic control of the trait. The markers HRG01, HRG02 and ORS511 were linked to the fertility restoration trait, with recombination rates between Rf1 locus and markers varying in different cross combinations. The analysis of VIR 116А × VIR 740 and VIR 116А × RIL 130 hybrids showed that among the marker loci studied, the ORS511 was closest to the Rf1 locus Rf1 (recombination frequency of 2.2 and 3.3%, respectively). The recombination rate between the Rf1 and ORS511 loci equaled 7.5% in the cross VIR 116А × VIR 210 and 8.9% in VIR 116 × VIR 195.</p></sec><sec><title>Conclusion</title><p>Conclusion. The markers ORS511, HRG01 and HRG02 are the most efficient for the identification of alleles of the Rf1 gene and for the marker assisted selection in hybrid populations produced involving sunflower lines from the VIR collection.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Helianthus annuus</kwd><kwd>ЦМС РЕТ1</kwd><kwd>восстановление фертильности пыльцы</kwd><kwd>маркер-опосредованный отбор</kwd><kwd>наследование</kwd><kwd>рекомбинация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Helianthus annuus</kwd><kwd>CMS PET1</kwd><kwd>pollen fertility restoration</kwd><kwd>marker assisted selection</kwd><kwd>inheritance</kwd><kwd>recombination</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Министерства науки и высшего образования России в рамках соглашения № 075-15-2020-911 от 16.11.2020 о предоставлении гранта в форме субсидий из федерального бюджета на осуществление государственной поддержки создания и развития научного центра мирового уровня «Агротехнологии будущего».</funding-statement><funding-statement xml:lang="en">The work was carried out with the support of the Ministry of Science and Higher Education of the Russian Federation in the framework of Agreement No. № 075-15-2020-911 of 16.11.2020 on providing a grant in the form of subsidies from the federal budget for the implementation of state support for the creation and development of the world-class scientific center “Agrotechnologies for the futureˮ.</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">Afjani J.A., Najafabadi M.S., Mirfakhraei R.G.
