Özet:

In this study, the morphological, physicochemical and biochemical properties of the fruit of the blackberry (Rubus spp.) genotypes grown naturally in the village of Dağdibi, Kaynaşlı district of Düzce province were determined. Fruit weights of the genotypes ranged from 1.77 g (81KYN10) to 0.80 g (81KYN2). Fruit width ranged from 13.55 mm (81KYN10) to 9.05 mm (81KYN2). Fruit length was determined between 14.26 mm (81KYN10) and 11.09 mm (81KYN2). In terms of the highest rate of amount of soluble solids content (SSC) in the study, 81KYN1 (16.70%), 81KYN3 (15.65%), 81KYN4 (15.40%), and 81KYN5 (16.20%) genotypes were more important. In terms of the highest titratable acidity (TA) value, 81KYN7 (0.52%) and 81KYN13 (0.51%) genotypes were more dominant. The highest L*, a*, b*, chroma and Hue angle values in color value parameters were found as 13.88 (81KYN7), 1.34 (81KYN4), 1.12 (81KYN4), 1.77 (81KYN4) and 40.63 (81KYN1), respectively. In terms of biochemical content, the highest total phenolic amounts were detected in 81KYN2 (45.77 mg GAE/g), 81KYN6 (47.55 mg GAE/g), 81KYN7 (52.16 mg GAE/g) and 81KYN13 (46.31 mg GAE/g) genotypes, the highest total antioxidant capacities were seen in 81KYN1 (29.30%) and 81KYN2 (30.57%) genotypes. Additionally, the highest total protein amounts was determined in 81KYN1 (20.48 g/L), 81KYN3 (20.60 g/L) and 81KYN5 (20.87 g/L) genotypes. As a result of the study, it was concluded that the genotypes that stand out in terms of morphological, physicochemical and biochemical characteristics can be evaluated in functional blackberry production.
