In this study, trans-resveratrol (t-RSV; 3,5,4′-trihydroxy-trans-stilbene) contents of the ripened berries of 23 clones of ‘Kalecik Karası’ which is one of Turkey’s leading red wine grape cultivars, grown in Ankara (Kalecik) were determined by HPLC. For this purpose; the berries were collected at 22–24 °Brix during 2016–2017 vintage seasons. Descriptive statistics for t-RSV content of clones were expressed as mean with their standard errors. One-way analysis of variance was performed for the comparison. Duncan multiple comparison test was used to determine the significant variances among clones. In addition, Analysis of Mean (ANOM) was also applied to determine the differences of the clones from the grand mean. As a result, t-RSV content of the clones ranged from 0.31 mg kg⁻¹ (Clone 22) to 1.67 mg kg⁻¹ (Clone 7) followed by Clone 6 with 1.12 mg kg⁻¹ and differences among the clones were statistically significant (p < 0.05).
