The vegetative and reproductive traits of the blackberry cultivar Hull Thornless, grown in different agro-ecological conditions of Bulgaria, was monitored. The study was conducted during the period 2022-2024 in a collection plantation of the Research Institute of Mountain Stockbreeding and Agriculture, Troyan and the Experimental Field at the Faculty of Agriculture of Trakia University - Stara Zagora. The indicators of average number, average height (m) and thickness of shoots (mm) of two linear meters of the inter-row area were monitored. The results show that the studied parameters were influenced by environmental factors during the study. Regarding vegetative indicators, the number of shoots (17 ± 6.34), the thickness of the shoots (14.85 mm ± 2.36) and the height of the shoots (3.49 m ± 0.32) are greater in the blackberry grown in the conditions of Troyan. During the tested period, the highest average yield (1666.33 g/2m) and average fruit weight (5.63 g) was recorded by the plants in the plantation of Stara Zagora.
