В данной работе по результатам многолетнего изучения 200 образцов питомника фитофтороустойчивых гибридов из генетической коллекции был выделен 31 образец со стабильно высоким проявлением признака по годам. Оценка производилась в полевых условиях и методом искусственного заражения клубней и листьев. Было определено наличие маркеров генов устойчивости методом ПЦР. По результатам проведенных испытаний данные образцы отличались высоким уровнем устойчивости листьев и клубней, характеризуются высоким уровнем ряда других селекционно значимых признаков. При этом отобранные образцы имели до 4 маркеров Rpi-генов, обусловливающих вертикальную устойчивость генотипов. Выявленные образцы могут быть использованы в селекционном процессе в качестве доноров высокого уровня устойчивости к фитофторозу.</p></abstract><trans-abstract xml:lang="en"><p>The study of potato genetic diversity using traditional and modern molecular genetic methods for identifying valuable genes allows for faster selection of desired genotypes with a set of economically important traits for use in breeding programs. In this research, based on the results of a long-term study of 200 nursery samples of late blight-resistant hybrids from the genetic collection, 31 samples with a consistently high manifestation of the trait over the years were selected. The assessment was carried out in the field and by the method of artificial infection of tubers and leaves. The presence of markers of resistance genes was determined by PCR. According to the results of the tests, these samples were characterized by a high level of stability of leaves and tubers, and are characterized by a high level of a number of other selection-significant features. At the same time, the selected samples had up to 4 markers of Rpi genes, which determine the vertical resistance of genotypes. The identified samples can be used in the breeding process as donors of a high level of resistance to late blight.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>картофель</kwd><kwd>фитофтороз</kwd><kwd>Phytophthora infestans (Mont.) de Bary</kwd><kwd>горизонтальная устойчивость</kwd><kwd>Rpi-гены</kwd><kwd>молекулярные маркеры</kwd><kwd>генетическая коллекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>potato</kwd><kwd>late blight</kwd><kwd>Phytophthora infestans (Mont.) de Bary</kwd><kwd>horizontal resistance</kwd><kwd>Rpi-genes</kwd><kwd>molecular markers</kwd><kwd>genetic collection</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Федерального исследовательского центра картофеля им.
