Blackberry cultivars that are well adapted, have high yield and have excellent fruit quality are important to successful fruit production. The main aim of the present study was to compare the performance of 11 blackberry cultivars cultivated under conditions of Nanjing, China during 2006-2009. Comparison of cane growth characters over these years showed that ‘Hull Thornless’ and ‘Chester Thornless’ had numerous and thick canes while ‘Thornless Young’ had much weaker cane growth. For morphological traits, ‘Boysen’ canes were sprawling, had dense prickles and ‘Hull Thornless’, ‘Chester Thornless’, ‘Brazos’ and ‘Kiowa’ had strong growth potential. As to fruit yielding, the 11 cultivars had distinct fruit ripening stage and duration time. ‘Thornless Young’ and ‘Boysen’ were especially early but had a short maturity duration of about 20 d. ‘Kiowa’ had the best average fruit yield per tree and fruit yield components, while ‘Thornless Young’ was weak in these aspects. Comprehensive analysis of the growth potential and yield ability revealed that eight cultivars including ‘Hull Thornless’, ‘Chester Thornless’, ‘Boysen’, ‘Kiowa’, ‘Choctaw’, ‘Brazos’, ‘Triple Crown’ and ‘Shawnee’ showed promise for planting in Nanjing and its environs of China. It is especially recommended that ‘Hull Thornless’, ‘Chester Thornless’, ‘Boysen’ and ‘Kiowa’ should be of great value for commercial growing in regions like Nanjing, China.
