Использование ранней оценки устойчивости получаемых гибридов с помощью фитопатологического тестирования и ДНК-маркеров позволяет ускорить этот процесс. Цель исследования состояла в комплексной оценке устойчивости к возбудителю парши гибридного потомства яблони, полученного от скрещивания восприимчивого (Ренет Симиренко) и устойчивого (Моди – донор гена Rvi6) сортов, с использованием естественного инфекционного фона и молекулярного маркирования целевого гена устойчивости. Фитопатологический анализ 207 гибридных сеянцев яблони на естественном фоне выявил 117 (56%) растений без поражений паршой (0 баллов). Оставшиеся сеянцы имели поражения разной степени. ДНК-маркерный анализ по гену Rvi6 позволил идентифицировать 105 растений (51%) с генотипом Rvi6rvi6 и 102 (49%) – rvi6rvi6, что близко к теоретическому расщеплению 1 : 1, получаемому при скрещивании такого типа. Сопоставление результатов инфекционной оценки и ДНК-маркирования показало 98% совпадений данных о наличии гена устойчивости с отсутствием поражений. В целом комплексное использование методов фенотипической и молекулярной оценки гибридной семьи на устойчивость к Venturia inaequalis (Cooke) G. Winter показывает высокую степень совпадения результатов. Однако несовпадение качественных классов реакций на инфицирование с результатами молекулярно-генетического анализа указывает на недостаточную силу естественного инфекционного фона года исследования. Низкая интенсивность развития заболевания была обусловлена неблагоприятными погодно-климатическими условиями начала вегетационного периода и становления инфекции, выражавшимися в более высокой по сравнению с нормой среднемесячной температурой и небольшим количеством осадков. Полученные нами результаты говорят о преимуществе комплексной оценки устойчивости к возбудителю парши с использованием инфекционного фона и молекулярного маркирования гена Rvi6, при котором на первом этапе проводится отбор устойчивых образцов на естественном инфекционном фоне с последующим подтверждением наличия искомого гена с помощью ДНК-маркерного анализа.</p></abstract><trans-abstract xml:lang="en"><p>The creation of highly scab-resistant apple genotypes increases the profitability and environmental friendliness of the production of this fruit crop. Early stage evaluation of the resistance using phytopathological testing and DNA markers allows to accelerate the process of breeding for this trait allows the use. The purpose of the study was to comprehensively assess resistance to the causative agent of scab of hybrid seedlings of apple obtained from crossing susceptible (Rennet Simirenko) and resistant (Modi) cultivars for the Rvi6 gene, using infectious background and marker assisted selection. A phytopathological analysis of 207 hybrid apple seedlings against the natural background of apple scab pathogen revealed 117 (56%) plants without scab lesions (0 points). The remaining seedlings had lesions of varying degrees. DNA marker analysis of the Rvi6 gene allowed identification of 105 plants (51%) with the Rvi6rvi6 genotype and 102 (49%) – rvi6rvi6, which is close to a theoretical segregation ratio 1:1 in the crosses of this type. Comparison of the results of infectious evaluation and DNA-marker analysis showed 98% coincidence of the presence of the resistance gene with no lesions. In general, the complex use of the phenotypic and molecular markers evaluation of the hybrid family for resistance to Venturia inaequalis (Cooke) G. Winter shows a high degree of agreement between the results of the methods. However, the discrepancy between the qualitative classes of reactions to infection and the results of molecular genetic analysis indicates an insufficient strength of the natural infectious background of the study year. The low efficiency of the development of the disease was due to the unfavorable weather and climatic conditions at the beginning of the vegetative period and the formation of infection, which were expressed in a higher average monthly temperature and a small amount of precipitation compared to the norm. Our results suggest an advantage, a comprehensive assessment of resistance to the scab pathogen using an infectious background and marker-assisted selection for the Vf gene (Rvi6) in which the first stage involves the selection of resistant samples against a natural infectious background, followed by confirmation of the presence of the desired gene using a DNA marker analysis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Venturia inaequalis (Cooke) G.
