Устойчивость к патогенам – важный селекционный признак сорта. Опасным заболеванием земляники является фитофторозная корневая гниль (Phytophthora fragariae var. fragariae Hickman). Выявление закономерностей наследования генетических детерминант устойчивости и идентификация перспективных генотипов является важным этапом селекционной работы по созданию устойчивых к фитофторозу сортов. Цель исследования – выявление закономерностей наследования маркера SCAR-R1A, сцепленного с геном Rpf1 устойчивости к фитофторозной корневой гнили, в гибридном потомстве земляники.Материалы и методы. Объектами исследования служили сорта земляники ‘Былинная’, ‘Олимпийская надежда’, ‘Привлекательная’, ‘Фейерверк’, а также гибридные сеянцы комбинаций скрещивания Былинная × Олимпийская надежда, Былинная × Фейерверк, Олимпийская надежда × Былинная, Привлекательная × Былинная, Фейерверк × Былинная. Для идентификации гена Rpf1 использовали доминантный маркер SCAR-R1A.Результаты и выводы. В гибридной комбинации Былинная × Олимпийская надежда количество сеянцев с предполагаемым аллелем резистентности Rpf1 (маркер SCAR-R1A присутствует) составило 33,3% от общего количества форм, в комбинации Былинная × Фейерверк – 37,2%, комбинации Олимпийская надежда × Былинная – 39,4%, комбинации Привлекательная × Былинная – 39,6%, комбинации Фейерверк × Былинная – 36,2%. Среднее количество сеянцев с аллелем Rpf1 по изучаемым комбинациям скрещивания составило 37,1%. Оценка соответствия фактического расщепления теоретическому по критерию χ2 подтвердила моногенный характер наследования изучаемого признака и соотношение частот наследования маркерных фрагментов гена Rpf1 как 1 : 1, следовательно все идентифицированные сеянцы с предполагаемым аллелем Rpf1 характеризуются гетерозиготным генотипом (Rpf1rpf1). Выявлены перспективные для вовлечения в селекционный процесс гибридные сеянцы земляники: 62-41 (Былинная × Фейерверк), 65-17, 65-24 (Олимпийская надежда × Былинная), 69-29 (Фейерверк × Былинная).</p></abstract><trans-abstract xml:lang="en"><p>Background. Resistance to pathogens is an important breeding trait of a cultivar. Red stele root rot (Phytophthora fragariae var. fragariae Hickman) is a dangerous root disease. Revealing the patterns of resistance inheritance and identifying promising genotypes is an important stage in the development of strawberry cultivars resistant to red stele root rot. The purpose of the study was to identify patterns of inheritance for the SCAR-R1A marker, linked to the Rpf1 red stele root rot resistance gene, in the strawberry hybrid combinations.Materials and methods. The target materials were the strawberry cultivars ‘Bylinnaya’, ‘Olimpiyskaya Nadezhda’, ‘Privlekatelnaya’ and ‘Feyyerverk’, and hybrid seedlings of the cross combinations Bylinnaya × Olimpiyskaya Nadezhda, Bylinnaya × Feyyerverk, Olimpiyskaya Nadezhda × Bylinnaya, Privlekatelnaya × Bylinnaya, and Feyyerverk × Bylinnaya. The Rpf1 gene was identified with the marker SCAR-R1A.Results and conclusion. For the hybrid combination Bylinnaya × Olimpiyskaya Nadezhda, the percentage of seedlings with an Rpf1 resistance allele was 33.3%. For the combination Bylinnaya × Feyyerverk, their percentage was 37.2%; for Olimpiyskaya Nadezhda × Bylinnaya, 39.4%; for Privlekatelnaya × Bylinnaya, 39.6%; and for Feyyerverk × Bylinnaya, 36.2%. The average percentage of seedlings with an Rpf1 allele for the studied combinations was 37.1%. Assessment of the compliance between the observed segregation and theoretical one according to the χ2  criterion confirmed the monogenic character of the studied trait and the Mendelian ratio of inheritance frequencies for the marker fragments of the Rpf1 gene as 1 : 1. Therefore, all identified seedlings with an Rpf1 allele are characterized by a heterozygous genotype. Strawberry hybrids promising for breeding were identified: 62-41 (Bylinnaya × Feyyerverk), 65-17, 65-24 (Olimpiyskaya Nadezhda × Bylinnaya), and 69-29 (Feyyerverk × Bylinnaya).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молекулярные маркеры</kwd><kwd>маркер-опосредованная селекция</kwd><kwd>генотип</kwd><kwd>гены устойчивости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molecular markers</kwd><kwd>marker-assisted selection</kwd><kwd>genotype</kwd><kwd>resistance genes</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках Государственного задания согласно тематическому плану ФНЦ имени И.В.
