Bioactive compounds in fruits of four Saskatoon berry genotypes grown in a trial in central Poland are presented in this paper. Two Polish breeding clones (no. 5/6 and type S) and two Canadian cultivars - 'Martin' and 'Smoky' - were used in studies conducted in 2015-2016. Fourty-eight bioactive compounds were identified in Saskatoon berry genotypes, including twenty-nine polyphenolic compounds (4 anthocyanins, 9 phenolic acids, 9 flavonols, 7 flavan-3-ols), 3 triterpenoids, 7 carotenoids, 5 chlorophylls and 4 tocopherols. The results of the analysis showed that the fruits of clone no. 5/6 had significantly lower contents of pro-healthy compounds and antioxidant activity in comparison to the other three tested genotypes. These genotypes, which may offer new functional material, can be recommended for fruit growers to increase their income. Their fruits can be used for the food processing industry and for the production of health beneficial products.
