The Saskatoon berry (Amelanchier alnifolia Nutt.) is a prospective and increasingly popular species in Poland. Its main attributes are extremely valuable fruits, rich in anthocyanins with high antioxidant activity, which are very valuable in processing. Studies aimed at comparing the suitability for cultivation under the climatic and soil conditions of east Poland of the three Canadian cultivars of Saskatoon berry (‘Honeywood’, ‘Martin’ and ‘Pembina’), were conducted at the Warsaw University of Life Sciences in 2017–2018. The study evaluated parameters such as yield and fruit quality, as well as the health-promoting value of the fruit. These studies revealed significant differences between the studied cultivars, both in yield and in fruit physicochemical properties, i.e., fruit mass and diameter, firmness, and soluble solids content, as well as in terms of the content of anthocyanins, flavonoids, and polyphenols. These differences were also found between years, which may indicate that the content of the abovementioned compounds is also influenced by annual climatic conditions.
