Растения выращивали в период с 2022 по 2024 г. в условиях Саратовской области. Оценку биохимических показателей зерна проводили с помощью инфракрасного анализатора Spectra Star XT модификации 2600XT-1, содержание танинов в муке сорго определяли по ГОСТ ISO 9648-2013. Установлены значимые различия в биохимическом составе у линий-закрепителей стерильности. Выявлены перспективные линии-закрепители стерильности с высоким содержанием крахмала, клетчатки и БЭВ – КВВ 181; крахмала и жира – КВВ 114; крахмала и БЭВ – КП-70. В среднем за 2022–2024 гг. цитоплазматический эффект на количество изученных биохимических компонентов в зерне изоядерных ЦМС-линий с разными типами стерильных цитоплазм отсутствовал. Исследуемые линии, за исключением изоядерных ЦМС-линий с геномом Карлик 4в, чей уровень был равен или несколько превышал 0,3 % (0,36 % у линии A3 Карлик 4в) в соответствии с пищевыми стандартами, характеризовались низким уровнем танинов от 0,14 до 0,25 %. Установлены сильные отрицательные корреляционные связи между содержанием золы и крахмала (r = -0,72), белком и БЭВ (r = -0,87). Выявлена отрицательная связь танинов с БЭВ (r = -0,61) и положительная – с белком (r = 0,50). Полученные сведения по влиянию цитоплазматического эффекта на биохимический состав зерна сорго позволяют более эффективно использовать выделенные источники в селекционном процессе при создании гибридов зернового сорго в зависимости от направления использования.</p></abstract><trans-abstract xml:lang="en"><p>The study reports on an investigation of the biochemical composition (fat, fiber, starch, protein, nitrogen-free extracts (NFE), tannin) in the seeds of 7 CMS grain sorghum lines with different types of sterile cytoplasm (A1, A2, A3, A4, A5, 9E) with the nuclear genome Karlik 4v and Zhelotozernoye 10, as well as 8 sterility-maintaining lines. The plants were grown from 2022 to 2024 in the Saratov region. The biochemical parameters of the grain were assessed using a Spectra Star XT 2600XT-1 infrared analyzer. The tannin content was determined in sorghum flour according to GOST ISO 9648-2013. There were found significant deviations in the biochemical composition of the sterilitymaintaining lines. Promising sterility-maintaining lines were identified: KVV 181 (high in starch, fiber and NFE); KVV 114 (high in starch and fat); KP-70 (high in starch and NFE). On average for 2022–2024, there was no cytoplasmic effect on the amount of the studied biochemical components in the grain of isonuclear CMS lines with different types of sterile cytoplasm. The studied lines, with the exception of isonuclear CMS lines with the Karlik 4v genome, whose level was equal to or slightly exceeded 0.3 % (0.36 % in the A3 Karlik 4v line) in relation to food standards, were characterized by a low level of tannins from 0.14 to 0.25 %. Strong negative correlations were found between ash and starch content (r = -0.72), as well as between protein and NFE (r = -0.87). A negative correlation was found between tannins and NFE (r = -0.61) and a positive correlation was found between tannins and protein (r = 0.50). The obtained data on the influence of the cytoplasmic effect on the biochemical composition of sorghum grain allow for more effective use of these sources in the breeding process when creating grain sorghum hybrids, depending on the intended use.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цитоплазматическая мужская стерильность</kwd><kwd>эффект ЦМС</kwd><kwd>крахмал</kwd><kwd>протеин</kwd><kwd>жир</kwd><kwd>танины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cytoplasmic male sterility</kwd><kwd>CMS effect</kwd><kwd>starch</kwd><kwd>protein</kwd><kwd>fat</kwd><kwd>tannins</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Министерства сельского хозяйства РФ в рамках Государственного задания (тема № 124020300041-5) и тематического плана ФГБНУ «Российский научно-исследовательский и проектно-технологический институт сорго и кукурузы»</funding-statement><funding-statement xml:lang="en">The research was carried out under the support of the Ministry of Agriculture of the Russian Federation within the state assignment (topic No. 124020300041-5) and the thematic plan of Russian Research, Design and Technology Institute of Sorghum and Corn</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">Assefa A., Bezabih A., Girmay G., Alemayehu T., Lakew A.
