В ряде стран, включая страны – импортеры гороха из России, возбудитель Pseudomonas syringae pv. pisi, вызывающий бактериоз некоторых зернобобовых культур, включен в карантинные перечни. Внедрение методов выявления и идентификации возбудителя болезни и поиск резистентных сортов стали актуальными в стратегии сохранения уровня экспорта гороха из России. С этой целью в ходе проведенной работы выбраны и проверены сорта гороха на устойчивость к фитопатогену. Для исследования был произведен посев пяти сортов гороха. После того как произошло прорастание в фазе 2–3 листьев, по 10 растений каждого сорта инокулировали бактериальной суспензией в концентрации 106 КОЕ/мл. Одно растение оставляли в качестве отрицательного контрольного образца, используя для инокуляции стерильную дистиллированную воду. В процессе развития проростков выполнялось сравнение зараженных растений с контрольным образцом, проводилась регистрация проявления симптомов заболевания. На 22-й день после заражения отобрали образцы вегетативных частей растений и провели контроль наличия клеток патогена, используя ПЦР-анализ с праймерами AN7F/AN7R. Согласно полученным результатам ПЦР-анализа, во всех пробах растений (в том числе и бессимптомных) подтверждено наличие специфического для возбудителя бактериального ожога гороха продукта амплификации размером 272 пары оснований (п. о.). В результате исследования выявлена восприимчивость сортов гороха к бактериозу у сортов гороха Варяг, Алтайский усатый, Астронавт. В ходе исследования установлено, что наиболее подходящим кандидатом для селекции сорта, резистентного к Pseudomonas syringae pv. pisi, стал сорт Амброзия. Также подтверждена необходимость оценки развития симптомов заражения фитопатогеном в совокупности с молекулярно-генетическими методами выявления ДНК бактерии в растительных клетках для подтверждения резистентности сорта к бактериальному ожогу гороха.</p></abstract><trans-abstract xml:lang="en"><p>Bacterial blight of pea is a main pea phytopathogen and is spread through seeds. In some countries, including those importing peas from Russia, Pseudomonas syringae pv. pisi causing bacteriosis of some leguminous crops is included in quarantine lists. Introducing detection and identification methods of the pathogen and determining resistant cultivars have become important in strategies for maintaining the level of pea exports from Russia. For this purpose, during this work, pea cultivars were selected and tested for their resistance to the phytopathogen. Five pea cultivars were planted for research. After germination occurred in the 2–3 leaf phase, 10 plants of each cultivar were inoculated with a bacterial suspension at a concentration of 106 CFU/ml. One plant was left as a negative control using sterile distilled water for inoculation. During the development of seedlings, infected plants were compared with a control sample, and the manifestation of disease symptoms was recorded. On the 22nd day after inoculation, samples of vegetative parts of the plants were taken and the presence of pathogen cells was monitored using PCR with primers AN7F/AN7R. According to the PCR results, in all plant samples (including asymptomatic ones), the presence of an amplification product with a size of 272 base pairs specific to the bacterial blight of peas pathogen was confirmed. As a result of the study, the susceptibility of pea cultivars to bacteriosis was revealed in the pea cultivars of Varyag, Altaisky Usatiy, Astronavt. The study determined that the most suitable cultivar for breeding, resistant to Pseudomonas syringae pv. pisi, was Ambrosia. The necessity of evaluating the development of phytopathogen infection symptoms together with molecular genetic methods for identifying bacterial DNA in plant cells to confirm the resistance of a cultivar to pea bacterial blight was also confirmed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Амплификация</kwd><kwd>инокуляция</kwd><kwd>ПЦР</kwd><kwd>резистентность</kwd><kwd>экспорт</kwd><kwd>фитопатогенная бактерия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Amplification</kwd><kwd>inoculation</kwd><kwd>PCR</kwd><kwd>resistance</kwd><kwd>export</kwd><kwd>phytopathogenic bacterium</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">Ареал и зоны вредоносности бактериального ожога гороха (научно-аналитический обзор) / Лазарев А.М., Коробов В.А., Надточий И.Н., Мысник Е.Н. // Научные ведомости.
