The taste characteristics of berries of 26 cultivars, elite and selected forms of blackberries grown in Central Russia are presented: dry matter, monosaccharides, sucrose acid the total amount of sugars. The sugar-acid index has been calculated. The best genotypes have been identified according to the content of dry matter and sugars - Brzezina and Agawam cultivars, elite seedlings LN-4, LN-13, LN-14 and selected seedlings LN-5, LN-7, LN-8, according to the content of organic (titrated) acids and sugar-acid index - Brzezina, Black Satin, Loch Tau, seedlings of Black Satin, Cheyenne, Loch Ness - LN-6, LN-10, EV LN-13 and control cultivar Agawam. A high traits’ conjugation was established: the sugar-acid index and the content of monosaccharides, the total amount of sugars, soluble solids, as well as a high inverse dependency between the content of organic acids and the sugar-acid index. Low unreliable correlation coefficients (r = - 0.28 … + 0.13) were obtained, indicating the absence of links between the fruit weight and the content of biochemical components responsible for the taste characteristics of genotypes, which is a positive fact when creating new cultivars with high taste and a significant weight of fruits, indicating their independent inheritance.
