The article presents the results of research on potato varieties in the Polissia zone of Ukraine. According to them, the adaptive potential, phenotypic stability and resistance to stressful environmental conditions were calculated based on the "yield" feature. According to the results of a comprehensive assessment, it was established that the general adaptive capacity according to the absolute coefficient of adaptability is characteristic of the following varieties: Prada, Sanibel, Riviera, Vzirets, Bellarosa, Zhytnytsia, Rodynna, Lilly, Yavir, Knyazha, Sluch, Toscana, Challenger. High stress resistance was found in potato varieties: Prada Predslava, Challenger. Genetic plasticity, which has a high degree of compatibility of the "genotype-environment" factors, was established in the varieties: Prada, Sluch, Bellarosa, Rodinna. According to the coefficient of variation, a high degree of variation (variability) was established in the varieties: Sluch, Vzirets. Varieties: Prada, Challenger, Predslava had slight variability. This assessment will contribute to the selection of potato varieties for profitable and economically profitable potato farming.
