Abstract: Promising potato hybrids, as further varieties, are one of the determining factors for an increase in crop productivity, sector stabilization and quality improvement of the final product. Therefore, one of the most crucial tasks of breeding is to find ways to manage the breeding process of development of early-ripening interspecific potato hybrids with high economic characters. At the initial stages of the research, it is essential to test the varieties in different geographical areas and identify their adaptive capacity, namely adaptability to specific soil and climatic conditions. The article presents the results of the studies that recog- nized promising interspecific hybrids in terms of their adaptability and suitability for cultivation in the European North tested from 2014 to 2017 in four points (Leningrad, Arkhangelsk and Murmansk regions and the Republic of Karelia). As a result of the research, two potato varieties were obtained: Eurasia (hybrid 5403/2) and Siversky (hybrid 3602/28). The cultivar Eurasia was allowed (in 2017) to be grown in the conditions of the Northwest region.
