Abstract :Blackberries are considered a rich source of phyitochemicals with high nutraceutical value and beneficial health effect. The objective of this work is to determine the berry size and compositional status of blackberry cultivars grown under Serbian conditions. For this purpose, fresh berries of seven blackberry cultivars insert ignore into journalissuearticles values(‘Black Satin’, ‘Dirksen Thornless’, ‘Chester Thornless’, ‘Thornfree’, ‘ Čačanska Bestrna’, ‘Loch Ness’ and ‘Navaho’ ); were used during two seasons. According to the results, the highest berry size was found in ‘ Čačanska Bestrna’ and ‘Loch Ness’, dry matter insert ignore into journalissuearticles values(DM); and titratable acidity insert ignore into journalissuearticles values(TA); in ‘Chester Thornless’ and pH value in ‘Dirksen Thornless’ . The highest content of soluble solids insert ignore into journalissuearticles values(SSC);, sugars content, SSC/TA rate and total sugars insert ignore into journalissuearticles values(TS);/TA rate was observed in ‘Navaho’, and mineral mater insert ignore into journalissuearticles values(MM); in ‘Loch Ness’ and ‘Chester Thornless’. The highest total phenolic content insert ignore into journalissuearticles values(TPH); and total antioxidant capacity insert ignore into journalissuearticles values(TAC); were found in ‘Black Satin’, total flavonoid content insert ignore into journalissuearticles values(TFC); in Thornfree, and ascorbic acid insert ignore into journalissuearticles values(AA); in ‘Loch Ness’. Based on the present results, the strong relationships between some phytochemicals, especialy between bioactive compunds, were observed. On the basis principal component analysis insert ignore into journalissuearticles values(PCA);, we segregated cultivars with better qualitty attributes, which were observed in ‘Navaho’ and ‘Loch Ness’, somewhat in ‘Chester Thornless’ and ‘Black Satin’.
