Abstract: The article presents the results of studying the reaction norm of introduced sweet potato varieties when grown in Polissia of Ukraine. Today, sweet potato is mainly grown in the southern regions of Ukraine. However, climate change contributes to introducing sweet potato, studying its adaptive properties, and selecting the most valuable samples suitable for cultivation in the Polissia zone of Ukraine. The research involved varieties such as Vinnytskyi rozhevyi, Afhanets, Betti, Bonita, Tainunh, Porto Amarello, Borehard, Manchzhurskyi, and Hocha. The cultivation of sweet potatoes was carried out in open ground, without the use of drip irrigation. The assessment included an evaluation of the development and diseases affecting the aboveground part of the plants, as well as the manifestation of productivity and its components. It was found that over the three years of research, Vinnytskyi rozhevyi, Hocha, Porto Amarello, performed the best, with plant development reaching 7–8 points. The corresponding yields were 1515 g/plant, 1190 g/plant, and 1064 g/plant, with marketability ranging from 84% to 96%. Among these varieties, Porto Amarello was characterized by uniform tubers, high marketability, and an average tuber weight of 423 g. Vinnytskyi rozhevyi also showed a high potential for cultivation in the Polissia region of Ukraine, with an average yield of 1515 g over the three years of research. In terms of marketability and average tuber weight, it slightly lagged behind Porto Amarello (84 % and 296 g, respectively).
