Özet:

The study was conducted in order to select those that have superior properties in terms of fruit properties in the genotypes of cornus (Cornus mas L.) naturally growing in the northern region of Vezirköprü (Samsun). During the two years (2015 and 2016) the study studied 70 genotypes and selected 13 genotypes as a result of a considerable rating based on the fruit weight, the meat/carbon ratio, the water-soluble dry substance and the vitamin C characteristics. In selected genotypes, the fruit weight is 1.90 g (K-10) to 4.25 g (K-12), the meat/carbon ratio is 4.08 (K-8) to 7.33 (K-12), the core weight is 0.30 g (K-7) to 0.56 g (K-13), the pH value is 2.58 (K-9) to 3.63 (K-13), the water soluble dry substance amount is 9.80 % (K-8) to 13.60 % (K-9), the vibrable acid amount is 0.49 % (K-2) to 1. 22 (K-9) and the vitamin C content varied between 24.45 mg 100 g-1 (K-9) and 76.05 mg 100 g-1 (K-3) A wide variation in terms of the characteristics studied among the selected genotypes was determined and as a result of the classification, the K-2 and K-12 genotypes were selected as hopeful. We believe that these genotypes can be a valuable genetic source for future recovery studies. In addition, the study of these selected genotypes in the same conditions by reproduction is important in order to more objective results.
