Опыты проводили в 2019-2021 гг. на Северном Кавказе в Республике Северная Осетия-Алания. Исходный in vitro материал высаживали в весеннем (апрель-июнь) и летнем (август-октябрь) оборотах в поликарбонатных теплицах в 5 л горшках с торфяным субстратом. Объектом для исследований являлись сорта картофеля Гулливер, Садон и Кумач. В качестве вариантов для закладки опыта использовали микрорастения (контроль), микроклубни стандартные (размер &gt; 9 мм в диаметре) и нестандартные (5-9 мм). По результатам проводимых биометрических наблюдений в период от образования всходов до достижения 20 см отмечено присутствие в вариантах с применением микроклубней невыравненности по высоте растений. В весеннем обороте выращивание мини-клубней из микрорастений способствовало формированию 6,9-8,0 шт/растение при выходе стандартной фракции 6,1-7,2 шт. Продуктивность в вариантах с высадкой микроклубней размером 5-9 мм снизилась в 1,6-1,9 раза по сравнению с микрорастениями. В летней культуре растения сформировали от 3,5 до 6,5 мини-клубней при выходе стандартной семенной фракции 53-72 %. Микроклубни размером &gt; 9 мм сортов Гулливер и Кумач летней посадки отмечены более продуктивными, чем микрорастения. В среднем они сформировали 6,1-6,7 шт. на растение, что превысило контрольный вариант на 0,8-2,1 шт. По результатам проводимых исследований, общее количество сформированных мини-клубней при летней посадке получено в 1,2-1,4 раза ниже, чем при весенней. Применение двух оборотов в процессе выращивания мини-клубней в защищенном грунте способствовало увеличению количественного выхода производимого семенного материала за вегетационный сезон в 1,7 раза. </p></abstract><trans-abstract xml:lang="en"><p>The aim of the research was to grow potato mini-tubers in two crop rotations of protected ground using micro-plants and micro-tubers in vitro as planting material. The experiments were carried out in 2019-2021 in the Republic of North OssetiaAlania (the North Caucasus). The initial in vitro material was planted in spring (April-June) and summer (August-October) rotations in 5 L pots filled with peat substrate. The pots were placed in polycarbonate-lined greenhouses. The objects for the research were the potato varieties Gulliver, Sadon and Kumach. Microplants (control), standard (&gt; 9 mm) and non-standard (5-9 mm) micro-tubers were used as variants for laying the experiment. According to the results of biometric observations in the period from sprouting to the plants reaching 20 cm, the presence of unevenness in plant height was noted in the variants with the use of micro-tubers. In the spring rotation, the cultivation of mini-tubers from microplants contributed to the formation of 6.9-8.0 pcs/plant with a standard fraction yield of 6.1-7.2 pcs. Productivity in variants with planting micro-tubers of 5-9 mm in size decreased by 1.6-1.9 times compared with micro-plants. In the summer rotation, the plants formed from 3.5 to 6.5 minitubers with a standard seed fraction yield of 53-72 %. Microtubers &gt; 9mm (potato varieties: Gulliver and Kumach) in summer planting were more productive than micro-plants. On average, they formed 6.1-6.7 pcs/plant, which exceeded the control variant by 0.8-2.1 pcs. According to the results of the research, the total number of formed mini-tubers during summer rotation was 1.2-1.4 times lower than during spring rotation. The use of two rotations in the process of growing mini-tubers in protected ground contributed to an increase in the quantitative yield of produced seed material for the growing season by 1.7 times. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Solnum tubersum L.</kwd><kwd>оригинальное семеноводство</kwd><kwd>микрорастения</kwd><kwd>микроклубни</kwd><kwd>мини-клубни</kwd><kwd>защищённый грунт</kwd><kwd>весенний оборот</kwd><kwd>летний оборот</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Solnum tubersum L.</kwd><kwd>original seed production</kwd><kwd>micro-plants</kwd><kwd>micro-tubers</kwd><kwd>mini-tubers</kwd><kwd>protected ground</kwd><kwd>spring rotation</kwd><kwd>summer rotation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Минобрнауки РФ в рамках Государственного задания ФГБНУ «Федеральный исследовательский центр картофеля имени А.
