%X Objective: In this study, the phenolic changes in the leaves of grape cultivars/genotypes belonging to different species and powdery also downy mildew diseases were examined for two years and the relationship between resistance to diseases and these components were evaluated. Material and Methods: 2 V. labrusca genotypes, 11 V. vinifera species/genotypes and 2 interspecies hybrids were studied. Mildew and powdery mildew disease was applied by artificial inoculation to species/genotypes and then total phenol content (spectrophotometric), antioxidant activity (spectrophotometric), routine (HPLC) and chlorogenic acid (HPLC) changes in leaf samples before and after the diseases were examined. Results: Although there was a significant increase in total phenol content and antioxidant activity after the diseases, there were differences in the amount of routine and chlorogenic acid. In addition, the study concluded that the FX1-1 was the most remarkable genotype because it was resistant to both diseases and contained a high amount of different phenolic compounds. Conclusion: As in many similar studies, it was observed that there were serious increases especially after the diseases in total phenol content and antioxidant activities. Most of the cultivars/genotypes used in the study were found to be resistant and tolerant according to the disease inoculation results. In the future studies, it will be useful to conduct comprehensive studies on the effects of total phenol content and antioxidant activity on the increase of the cause and the effects on the resistance to diseases
