Abstract :In this study, agro-morphological characteristics of raspberry (Rubus idaeus Linnaeus) genotypes naturally grown in Çivril, the central district of Bolu province in Türkiye were determined. In the study, parameters belonging to the genotypes were determined as follows: fruit weight was between 2.52 g (Genotype 4) and 1.30 g (Genotype 2), fruit width was between 18.18 mm (Genotype 6) and 15.33 mm (Genotype 2), fruit length was between 18.45 mm (Genotype 6) and 12.87 mm (Genotype 2), seed width was between 1.30 mm (Genotype 4) and 1.10 mm (Genotype 6), seed height was between 2.37 mm (Genotype 1) and 1.84 mm (Genotype 6). In addition, in genotypes, fruit stem thickness ranged from 0.91 mm (Genotype 4) to 0.67 mm (Genotype 5), fruit stem pit depth ranged from 13.99 mm (Genotype 6) to 10.58 mm (Genotype 5), fruit stem pit width ranged from 10.08 mm (Genotype 4) to 7.82 mm (Genotype 9). Also, genotype 3 (13.80%) had the highest soluble solids content (SSC) and Genotype 9 (3.60%) had the highest titratable acidity (TA). The pH values observed in the genotypes varied between 3.06 and 3.29. Also, in color value parameters, the highest L*, a*, b*, chroma and hue° angle values were 32.22 (Genotype 8), 23.75 (Genotype 1), 12.86 (Genotype 1), 27.10 (Genotype 1) and 28.22 (Genotype 1), respectively. As a result of the study, it was concluded that various genotypes that stand out in terms of agro-morphological characteristics can be evaluated as breeding material in functional raspberry production.
