Цель исследований – установить методами корреляционного и путевого анализов взаимосвязи между хозяйственно ценными признаками сортов картофеля для дальнейшего использования результатов в программах селекции на повышенную продуктивность. Погодные условия вегетационных периодов отличались по гидротермическому коэффициенту (ГТК): 2022 г. – благоприятный по теплу и влагообеспеченности (ГТК = 1,02); 2023 г. – засушливый (ГТК = 0,78); 2024 г. – переувлажненный (ГТК = 1,63). Согласно основным показателям урожайности дана характеристика сортов для эффективного использования их потенциала. Выделены сорта: Крепыш (Россия) – с высокой урожайностью (30,8 т/га) и массой товарного клубня (88,3 г); Гала (Германия) и Гранд (Россия) – с наибольшим количеством клубней (11,4 и 10,7 соответственно) при небольшой массе товарного клубня, которые можно использовать для переработки. Корреляционная взаимосвязь установлена между урожайностью и массой товарного клубня в 2022 г. (r = 0,418) и 2023 г. (r = 0,504), а в 2024 г. – между урожайностью и количеством клубней на одном кусте (r = 0,434). Для разработки эффективной программы селекции, используя интеграцию статистических методов (расчет путевых коэффициентов) с селекционной оценкой, определена наибольшая селекционная ценность отдельных количественных признаков растений картофеля, связанных с урожайностью. Обнаружен высокий и положительный прямой эффект на урожайность признаков «масса товарного клубня» (2022-2023 гг.) и «количество стеблей на растении» (во влажный 2024 г.); очень низкий (2022-2023 гг.) – «количество стеблей на растении» и незначимый – «товарность урожая». Признак «масса товарного клубня» может быть использован при отборе исходного материала для селекции картофеля на повышенную продуктивность.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of study of 12 potato cultivars in the Omsk region (2022–2024). The aim of the research was to establish relationships between economically valuable traits of potato cultivars using correlation and path analysis methods for their further use in breeding programs aimed at increasing productivity. The weather conditions during the growing seasons differed in terms of hydrothermal coefficient (HTC): 2022 – favorable in terms of heat and moisture supply (HTC = 1.02); 2023 – dry (HTC = 0.78); 2024 – wet (HTC = 1.63). Based on the main yield parameters, the cultivars were characterized for the effective use of their potential. The following varieties were identified: ‘Krepysh’ (Russia) – with high yield (30.8 t/ha) and marketable tuber weight (88.3 g); ‘Gala’ (Germany) and ‘Grand’ (Russia) – with the highest number of tubers (11.4 and 10.7) with low weight of marketable tuber suitable for processing. Correlation relationship was established between the yield and marketable tuber weight in 2022 (r = 0.418) and 2023 (r = 0.504), and in 2024 – between the yield and the number of tubers per plant (r = 0.434). To develop an effective breeding program, using the integration of statistical methods (calculation of path coefficients) with breeding assessment, the highest breeding value of individual quantitative traits of potato plants was determined. A high positive direct effect on the yield was found for the “marketable tuber weight” trait (2022-2023) and “the number of stems per plant” (in the wet 2024); a very low effect (2022-2023) for the “number of stems per plant” trait and an insignificant effect for the “marketability” trait. The “marketable tuber weight” trait can be used in the selection of source material for potato breeding for increased productivity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Solanum tuberosum L.</kwd><kwd>урожайность</kwd><kwd>прямой и косвенный эффект</kwd><kwd>взаимосвязь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Solanum tuberosum L.</kwd><kwd>yield</kwd><kwd>direct and indirect effect</kwd><kwd>relationship</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Минобрнауки РФ в рамках Государственного задания ФГБНУ «Омский аграрный научный центр» (тема № FNUN-2023-0010)</funding-statement><funding-statement xml:lang="en">The research was carried out with the financial support of the Ministry of Science and Higher Education of the Russian Federation within the state assignment of the Omsk Agrarian Scientific Center (theme No. FNUN-2023-0010)</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">Мухордова М.
