Blackberry is a new berry crop of industrial horticulture in the central part of Russia. More than 20 blackberry varieties were collected at the experimental sites of the SPC “Agropishcheprom". The paper presents the results of the study of 11 modern blackberry varieties. During preparation for winter, the plants were covered with covering material, and therefore, no winter damage was found during the years of research. A fluctuation in the accumulation of positive temperatures during the period of fruit formation and maturation, affecting the biochemical parameters and taste of fruits, was revealed. There is also a difference in the amount of precipitation over the years, which affects the average fruit weight. Thus, in 2020, during the formation and maturation of the fruits, 40% less precipitation fell in comparison with 2019, which led to a decrease in the average fruit weight. As a result of the research, the varieties were grouped according to maturation period, fruit average weight and taste. Selected varieties for use in breeding for large-fruited are the following: Natchez, Karaka Black, Black Butte and Triple Crown. Loch Maree, Natchez, Polar, Triple Crown, Black Butte and Karaka Black varieties were characterized by high taste qualities.
