The article describes the findings of a comparative study of the sugar-acid index, content of free organic, ascorbic, and hydroxycinnamic
acids, dry, tanning, and pectic substances, soluble sugars, and the main groups of bioflavonoids in fruit of six newly introduced Oxycoccus
macrocarpus (Аit.) Рers. cultivars in Belarus — Stevens (st), Bain Favorite, Holliston, Hollister Red, Stankovich, and WSU 108. It is
established that the Hollister Red cultivar has the highest integrated level of nutritive and vitamin value of fruit based upon the combination of
properties analyzed, from 1.8 to 11 times the level observed in the other cultivars, whereas the WSU 108 and especially the Bain Favorite
cultivars have the lowest levels.
