Увеличение распространения бактериоза на свекле столовой в условиях Московской области несет эпидемиологическую опасность, что актуализирует исследования по разработке методики оценки растений на устойчивость к бактериозу на ранних стадиях онтогенеза.</p></sec><sec><title>Цель</title><p>Цель. Выявить характер взаимосвязи между реакцией спорофита и микрогаметофита на заражение бактерией Pseudomonas syringae pv. aptata (Psa) сортов свеклы столовой с различной устойчивостью корнеплодов к бактериозу.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Объекты исследований: растения свеклы столовой сортопопуляций Маруся и Красный бархат, коллекционный штамм Psa 1-21. С применением фитопатологических методов и методов гаметной селекции проводили оценку устойчивости растений в различных вариантах заражения спорофита и гаметофита суспензией и культуральным фильтратом Psa.</p></sec><sec><title>Результаты</title><p>Результаты. Средний объем зоны поражения Psa корнеплодов сорта Маруся был в 3,5 раза больше, чем у сорта Красный бархат (Vп=53 мм3), который характеризовался выровненностью и отсутствием восприимчивых форм Vп&gt;300 мм3). У сорта Маруся выявлен широкий внутрипопуляционный полиморфизм по устойчивости корнеплодов и листьев, где большинство генотипов проявили среднюю или высокую восприимчивость к возбудителю. У обоих сортов отмечено повышение на 10-30% относительно контроля жизнеспособности пыльцы при высокой (КОЕ 12х108 кл/мл) и низкой (КОЕ 2,4х108 кл/мл) концентрациях патогена. Отмечено положительное влияние Psa на рост пыльцевых трубок: у сорта Маруся по мере увеличения концентрации стимулирующий эффект возрастал, у сорта Красный бархат - постепенно снижался. При добавлении разбавленного в 2,5 раза культурального фильтрата Psa у восприимчивого сорта Маруся отмечено повышение жизнеспособности пыльцы (на 3%), у устойчивого сорта Красный бархат - снижение на 24% относительно контроля. По скорости роста пыльцевой трубки дифференцирующим было также разведение 4:6, где средняя длина трубок восприимчивого сорта превысила контроль на 10%, а у устойчивого сорта была ниже контрольного варианта на 18%.</p></sec><sec><title>Заключение</title><p>Заключение. Выявлена обратная взаимосвязь между устойчивостью спорофита к Psa и изменением функциональных параметров микрогаметофита сортов свеклы столовой Маруся и Красный бархат под влиянием фитопатогена. Полученные результаты свидетельствуют о перспективах разработки методики отбора устойчивых к бактериозу генотипов свеклы столовой по реакции микрогаметофита.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. An increase in the spread of bacteriosis on beetroot in the conditions of the Moscow region carries an epidemiological danger, which actualizes research on the development of a method-ology for evaluating table beet plants for resistance to bacteriosis in the early stages of ontogenesis. The aim of the research. To identify the nature of the relationship between the reaction of sporophyte and microgametophyte to infection with Pseudomonas syringae pv. aptata (Psa) bacterium of beet-root varieties with different resistance of root crops to bacteriosis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Objects of research: beetroot plants of the Marusya and Krasny Barhat varietal populations, collection strain Psa 1-21. Using phytopathological methods and methods of gamete breeding, plant resistance was assessed in various variants of infection of sporophyte and gametophyte with suspension and culture filtrate of Psa.</p></sec><sec><title>Results</title><p>Results. The average volume of the affected area of the Psa root crops of the Marusya variety was 3.5 times greater than that of the Krasny Barhat variety (Vp = 53 mm3), which is characterized by alignment and absence of susceptible forms (Vp &gt;300 mm3). The Marusya variety has a wide intrapopulation polymorphism in the stability of root crops and leaves, where most genotypes showed medium or high susceptibility to the pathogen. Both varieties showed an increase of 10-30% relative to the control of pollen viability at high (CFU 12*108 cl/ml) and low (CFU 2.4*108 cl/ml) concentrations of the pathogen. The positive effect of Psaon the growth of pollen tubes was noted: in the Marusya variety, as the concentration increased, the stimulating effect increased, in the Krasny Barhat variety, it gradually decreased. When adding a 2.5-fold diluted Psa culture filtrate, the susceptible Marusya variety showed an increase in pollen viability (by 3%), and the resistant Krasny Barhat variety showed a 24% decrease relative to the control. According to the growth rate of the pollen tube, the 4:6 dilution was also differentiating, where the average length of the tubes of the susceptible variety exceeded the control by 10%, and in the stable variety it was 18% lower than the control variant.</p></sec><sec><title>Conclusion</title><p>Conclusion. An inverse relationship was revealed between the resistance of sporophyte to Psa and changes in the functional parameters of the microgametophyte of beetroot varieties Marusya and Krasny Barhat under the influence of a phytopathogen. The results obtained indicate the prospects for the development of a methodology for the selection of bacteriosis-resistant genotypes of beetroot by the reaction of microgametophyte.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>свекла столовая (Beta vulgaris L.)</kwd><kwd>Pseudomonas syringae pv. aptata</kwd><kwd>устойчивость</kwd><kwd>микрогаметофит</kwd><kwd>спорофит</kwd><kwd>симптомы бактериоза</kwd><kwd>корреляционная зависимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>beetroot (Beta vulgaris L.)</kwd><kwd>Pseudomonas syringae pv. aptata</kwd><kwd>resistance</kwd><kwd>microgametophyte</kwd><kwd>sporophyte</kwd><kwd>symptoms of bacteriosis</kwd><kwd>correlation dependence</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены по Государственному заданию FGGF-2022-0016, FGGF-2024-0020.</funding-statement><funding-statement xml:lang="en">The research was carried out under State Assignment FGGF-2022-0016, FGGF-2024-0020.</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">Ветрова С.А., Вюртц Т.С., Заячковская Т.В., Степанов В.А.
