In the years 2021-2023, field experiments  were conducted to assess and select the most stable potato varieties for cultivation in an organic production system in terms of specific component content. The experiments were conducted in six locations (Jadwisin, Krzyżewo, Lućmierz, Osiny, Tarnów, Węgrzce) on ten edible potato varieties (very early: Pogoria, Surmia, Tonacja, early: Arizona, Lilly and medium early: Connect, Irmina, Mariola, Red Lady, Soraya). The content of basic components was determined in the tubers after harvest: starch, vitamin C, nitrates (V), glycoalkaloids and dry matter. The results were developed based on the analysis of variance using the AMMI model. The significance of the studied factors and their share in variability were assessed. Then, the stability of the analyzed features of the tubers of the studied varieties was determined based on three measures: the measure feature superiority - Pi, eskridey’s feature reliability measure - Ri, Kang’s stability measure - YSi. The greatest influence of the environmental factor on the content of vitamin C, nitrates (V) and glycoalkaloids was obtained, and the variety factor on the level of starch and dry matter in tubers. The environmental factor had the greatest impact on the content of vitamin C, nitrates (V) and glycoalkaloids, and the variety factor had the greatest impact on the level of starch and dry matter in tubers. The highest degree of broad adaptation of the analyzed measures in relation to the content of dry matter and starch was obtained by the Mariola variety, vitamin C by the Lilly variety, nitrates (V) by the Tonacja variety and glycoalkaloids by the Red Lady variety.
