The productivity of twenty-five blackberry cultivars of Ukrainian and foreign breeding in the condi-tions of Right-Bank part of the western Forest-Steppe of Ukraine has been evaluated. The trailing Thornfree culti-var, characterized by an average shoot–forming ability and a large number of fruit-bearing branches and berries on them, had the highest productivity, namely 5,14 kg/bush; 9,59 t/ha on average, over the years of research (2016-2017). The semi-erect blackberries Asterina, Heaven can Wait and Orkan were also found to be high-yielding. The remontant cultivars Reuben and Black Magic, characterized by late fruit setting, gave low yields (020/kg/bush; 0,47 t/ha and 0,38 kg/bush; 1,00 t/ha respectively). The Black Butte Blackberry and Kiowa varieties were distinguished by the highest average mass per berry, namely 9,5 g and 8,22 g, respectively. Most of the studied blackberry cultivars have medium-sized berries ranging from 4,4 to 5,8 g.
