Abstract :
This study aimed to determine the amount of quality characteristics, such as soluble solids, pH, titratable acidity (tartaric acid) and organic acid of grapevine cultivars grown in Sivas-Gemerek region. Nine grapevine cultivars, Karabekir, Göğcek, Dişieldaş, Kabaeldaş, Gülüzümü, Amber, Patlakkara, Dikkarabekir and Memeüzümü, were examined in the study. Organic acid amount and compositions of the cultivars were determined by High-Pressure Liquid Chromatography (HPLC) and differences between the cultivars were found statistically significant (p 0.05) for all organic acids except citric acid. On the other hand, there was no significant difference among the cultivars for soluble solid, pH and titratable acidity. Soluble solid content of the cultivars ranged from 17% to 20 % ° Brix°, and TA content from 0.6% to 0.8%. Similarly, pH varied from 2.4 to 2.8. In addition, tartaric acid, malic acid, citric acid, succinic acid and fumaric acid contents of the cultivars were found 3.25 to 4.21, 1.34 to 2.05, 0.30 to 0.50, 0.11 to 0.46, and 0.05 to 0.29 g/l, respectively. By considering all variables in the study, cluster analysis’ results showed that similarity level among the nine cultivars was about 64%. It can be stated that this similarity level, in other words, 36% of the phenotypic variation among the cultivars can be considered to breeding studies.
