Интрогрессивную гибридизацию используют для увеличения генетического разнообразия и повышения устойчивости к болезням мягкой пшеницы Triticum aestivum L. Интрогрессии от тетраплоидной пшеницы Triticum timopheevii (Zhuk.) Zhuk. subsp. timopheevii в мягкую пшеницу ‘Саратовская 29’ (S29) помогли повысить ее устойчивость к грибным заболеваниям. Необходимы исследования влияния интрогрессивной гибридизации на устойчивость пшеницы к абиотическим стрессорам. </p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В контролируемых условиях при двух режимах водоснабжения исследовали параметры газообмена и флуоресценции хлорофилла, содержание хлорофиллов a и b, каротиноидов, свободного пролина, активность ферментов аскорбат-глутатионового цикла, каталазы и липоксигеназы в листьях и биомассу побега у сорта пшеницы S29 и линии S29 (821 5A), несущей сегмент интрогрессии от T. timopheevii subsp. timopheevii в дистальном участке хромосомы 5AL. Компоненты продуктивности изучали в гидропонной теплице в двух режимах водоснабжения.</p></sec><sec><title>Результаты</title><p>Результаты. По сравнению с сортом S29 линия S29 (821 5A) показала сниженное количество поглощаемой и переносимой энергии на один реакционный центр фотосистемы II при оптимальном поливе. Также у линии на 30% снизилась активность ферментов аскорбат-глутатионового цикла и значительно повысилось содержание пролина в листьях. У линии S29 (821 5A) отмечены ослабленные защитные реакции на стресс от засухи. Она уступала сорту S29 по продуктивности главного колоса, независимо от условий полива. </p></sec><sec><title>Заключение</title><p>Заключение. Интрогрессия от T. timopheevii subsp. timopheevii в дистальную область хромосомы 5AL отрицательно повлияла на устойчивость к засухе и продуктивность мягкой пшеницы. Для комплексной оценки устойчивости межвидовых гибридов к неблагоприятным факторам необходимы физиолого-биохимические исследования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Introgressive hybridization is used to increase genetic diversity and improve disease resistance in bread wheat Triticum aestivum L. Introgressions from tetraploid wheat Triticum timopheevii (Zhuk.) Zhuk. subsp. timopheevii into bread wheat ‘Saratovskaya 29’ (S29) helped to increase its resistance to fungal diseases. There is a need for thorough studies into the effect of introgressive hybridization on tolerance to abiotic stressors in wheat.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Gas exchange and chlorophyll fluorescence parameters, chlorophyll a and b content, carotenoids, free proline, ascorbate-glutathione cycle enzyme activity, catalase and lipoxygenase in leaves, and shoot biomass were analyzed in wheat cultivar S29 and line S29 (821 5A) carrying a T. timopheevii subsp. timopheevii introgression segment in the distal region of chromosome 5AL, under controlled conditions with two water-supply regimes. Productivity components were assessed in a hydroponic greenhouse, also under two water-supply regimes.</p></sec><sec><title>Results</title><p>Results. Compared with cv. S29, line S29 (821 5A) had a reduced amount of absorbed and transferred energy per reaction center of photosystem II under optimal watering. The line also had a 30% reduction in the activity of ascorbate-glutathione cycle enzymes and a significantly increased proline content in leaves. Line S29 (821 5A) showed weakened defense reactions to drought stress. It was inferior to cv. S29 in the main spike productivity, regardless of watering conditions.</p></sec><sec><title>Conclusion</title><p>Conclusion. Introgression from T. timopheevii subsp. timopheevii into the distal region of chromosome 5AL negatively affected the drought tolerance and productivity of bread wheat. Physiological and biochemical studies are required to make a comprehensive assessment of interspecific hybrids for their resistance to unfavorable factors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фотосинтез</kwd><kwd>активность антиоксидантных ферментов и липоксигеназы</kwd><kwd>пролин</kwd><kwd>компоненты проlуктивности</kwd><kwd>опушение листа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photosynthesis</kwd><kwd>antioxidant enzyme and lipoxygenase activity</kwd><kwd>proline</kwd><kwd>productivity components</kwd><kwd>leaf pubescence</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено в рамках реализации государственных заданий СИФИБР СО РАН № 0277-2025-0006 «Изучение механизмов формирования, поддержания и регуляции устойчивого состояния растений: генетические, физиолого-биохимические, эволюционные и экологические аспекты» и ФНЦ ИЦиГ СО РАН по проекту № FWNR-2022-0017 «Генетический контроль развития и формирования хозяйственно-ценных признаков у сельскохозяйственных растений».
