В современных нестабильных погодных условиях умеренно континентального климата юга России, антропогенной интенсификации производства и увеличения спроса на отечественные сорта винограда возрастает актуальность селекции генотипов с повышенными показателями продуктивности и качества ягод, адаптационного потенциала растений. Наращивание доли современных отечественных сортов столового винограда позволит обновить и улучшить сортимент. Целью настоящего исследования являлась оценка новых гибридных форм винограда по агробиологическим и физиолого-биохимическим характеристикам в центральной агроэкологической зоне Краснодарского края.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Агробиологические показатели винограда определяли с использованием современных методов исследований. Среди физиолого-биохимических показателей у исследованных гибридных форм оценивали содержание фотосинтетических пигментов, а также уровень стрессовых параметров при засухе, таких как содержание общей воды в листьях и содержание малонового диальдегида. Искусственную засуху проводили с целью выделения наиболее устойчивых к стрессовому фактору гибридных форм.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено, что наибольшие значения коэффициентов плодоношения и плодоносности за исследованный период характерны для гибридных форм Акелло и Агат Дубовский, максимальной урожайности – для гибридов Тимоти и Агат Дубовский. Генотипы Гамлет, Кишмиш Дубовский, Агат Дубовский и Тимоти существенно превосходили контрольный сорт ‘Ливия’ по массе грозди. По физиолого-биохимическим параметрам были выделены гибриды Акелло и Агат Дубовский, которые обладали наибольшим содержанием хлорофилла в листьях, а также высоким адаптационным потенциалом, выраженным низким уровнем развития вторичных окислительных процессов при стрессе и наибольшим содержанием каротиноидов.</p></sec><sec><title>Заключение</title><p>Заключение. По совокупности показателей установлено, что гибридная форма Агат Дубовский может быть охарактеризована как наиболее перспективная среди исследованных генотипов для выращивания на юге России.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Development of table grape cultivars is currently aimed not only at higher vineyard productivity and grape quality but also at enhancing the adaptive potential of plants under the dynamic change in the climate conditions of Southern Russia. Increasing the share of modern Russian cultivars of table grapes will update and improve the assortment. The aim of this study was to evaluate new Russian hybrid grapevine forms according to their agrobiological, physiological and biochemical characteristics in the central agroecological zone of Krasnodar Territory.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Agrobiological characters were assessed using modern methods. Among physio-biochemical characters, the content of photosynthetic pigments was measured as well as the level of stress parameters under drought, such as the total water content in leaves and the content of malondialdehyde. Artificial drought was simulated to identify the most stress-resistant hybrid forms.</p></sec><sec><title>Results</title><p>Results. The highest values of fruitfulness coefficients k1 and k2 in the period of research were recorded for the Akello and Agat Dubovsky hybrid forms. Timoti and Agat Dubovsky had the maximum average yield for two years among the hybrid forms. The Gamlet, Kishmish Dubovsky, Agat Dubovsky and Timoti genotypes significantly exceeded the reference cultivar in the bunch weight. The Akello and Agat Dubovsky hybrids were identified for their physio-biochemical parameters: the highest content of chlorophyll in their leaves, high adaptive potential expressed in a low development level of secondary oxidative processes under stress, and the highest content of carotenoids.</p></sec><sec><title>Conclusion</title><p>Conclusion. The obtained results evidenced that the Agat Dubovsky hybrid form could be identified as the most promising among the studied genotypes for cultivation in Southern Russia.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>масса грозди</kwd><kwd>урожай</kwd><kwd>абиотические стрессы</kwd><kwd>адаптационный потенциал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bunch weight</kwd><kwd>yield</kwd><kwd>abiotic stresses</kwd><kwd>adaptive potential</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Кубанского научного фонда в рамках научного проекта № МФИ-20.1/20.
