В настоящее время для криоконсервации сортов картофеля наиболее широко используется метод дроплет-витрификации, который постоянно совершенствуется с целью повышения регенерационной способности сохраняемого растительного материала. В ведущих мировых генбанках картофеля используются различные модификации этого метода. В данной работе представлены результаты изучения влияния условий культивирования после замораживания–оттаивания апексов побегов и пазушных почек in vitro растений на их способность к посткриогенному восстановлению. Для криоконсервации был использован метод дроплет-витрификации, модифицированный в ВИР. Фактор «длительная темновая инкубация эксплантов» не оказывал существенного влияния на частоту посткриогенной регенерации изученных сортов, за исключением одного сорта (Крепыш), для которого отмечено достоверное (p &lt; 0.05) увеличение частоты регенерации в варианте культивирования апексов микропобегов в темноте по сравнению с вариантом культивирования при фотопериоде 16/8 ч (свет/темнота). Фактически у всех сортов частота посткриогенной регенерации апексов микропобегов была выше, чем у пазушных почек, однако достоверное превышение (p &lt; 0.05) данного показателя для апексов побегов отмечено только в двух случаях: для сорта Удача – культивирование эксплантов при фотопериоде 16/8 ч и для сорта Крепыш – культивирование в условиях темновой инкубации. Результаты двухфакторного дисперсионного анализа указывают на отсутствие значимого эффекта совместного действия двух факторов (темновая инкубация и тип экспланта) на способность сортов к посткриогенному восстановлению. С учетом полученных результатов дальнейшую криоконсервацию расширенной выборки из девяти селекционных сортов проводили с использованием только одного типа эксплантов – апексов микропобегов, которые после замораживания–оттаивания культивировали при фотопериоде 16/8 ч. Частота посткриогенной регенерации этих сортов варьировала от 30 до 60 %. Установлено достоверное влияние генотипа на регенерационную способность сортов после замораживания–оттаивания. Способность сортов к посткриогенному восстановлению не связана со значениями морфогенетических показателей in vitro растений, которые используются в оригинальном семеноводстве картофеля. Возраст мериклона (2–4 года) не оказывал существенного влияния ни на показатели морфогенеза, ни на частоту посткриогенной регенерации сортов.</p></abstract><trans-abstract xml:lang="en"><p>Cryopreservation provides long-term storage of the gene pool of potato varieties in cryobanks at extremely low temperatures. Currently, droplet vitrification is the most widely used method for cryopreservation of potato varieties, which is constantly improving to increase the regeneration rates of the stored plant material. Different modifications of this method are used in the world’s leading potato genebanks. This paper presents the results of studying the effect of cultivation conditions after plunging into liquid nitrogen and thawing of shoots tips and axillary buds of in vitro plants on their postcryogenic recovery. The droplet-vitrification method modified at VIR was used for cryopreservation. The factor “prolonged dark incubation of explants” did not have a significant effect on the frequency of post-cryogenic regeneration of the studied varieties except for one variety (Krepysh), for which a significant increase in the regeneration rate was observed for the shoot tips cultivated in the darkness compared to the cultivation under the photoperiod 16/8 hours (light/darkness). The frequency of post-cryogenic regeneration of shoot tips was higher than that of the axillary buds for all varieties; however, these differences were significant (p &lt; 0.05) only in two cases: for the variety Udacha (a photoperiod of 16/8 hours) and for the variety Krepysh (the dark incubation). The results of two-factor analysis of variance indicate that there is no effect of interaction of factor 1 (prolonged dark incubation) and factor 2 (explant type) on the ability of varieties to post-cryogenic recovery. Taking into account the obtained results, the further cryopreservation of an extended subset of 9 varieties was carried out using shoot tips, which, after freezing-thawing, were cultivated under the photoperiod of 16/8 hours. The frequency of post-cryogenic regeneration of these varieties varied from 30 to 60 %. A significant effect of genotype on postcryogenic recovery has been established. The ability of varieties to regenerate shoots after freezing and thawing was not related to the values of morphogenic indices of in vitro plants. The age of the meriklons (2–4 years) did not significantly affect either the morphogenic indices or the frequency of post-cryogenic regeneration.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>картофель</kwd><kwd>Solanum tuberosum</kwd><kwd>длительное хранение</kwd><kwd>криоконсервация</kwd><kwd>условия in vitro культивирования</kwd><kwd>морфогенез in vitro растений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>potato</kwd><kwd>Solanum tuberosum</kwd><kwd>long-term preservation</kwd><kwd>cryoconservation</kwd><kwd>in vitro cultivation conditions</kwd><kwd>in vitro morphogenesis</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>The authors are grateful to Cand.
