The aim of this study is to compare the 'Granny Smith' apple variety, which is well-known to withstand storage, and the 'Ayvaniye' apple, a local variety, in terms of some quality characteristics, and to determine their suitability for storage. The apples included in the experiment were stored at 1±0.5 °C and 90±5% relative humidity for 6 months. Measurements and analyses were done once a month from the beginning to the end of storage. The parameters examined in the trial are: Weight loss, fruit flesh firmness, pH, titratable acidity (TA), soluble solids content (SSC), total phenolic substance content (TPC), total antioxidant activity (TAA) and fruit outer colour (L*, a*, b*). As a result; weight loss, pH, TA, SSC, TAA, L* and a* parameters were found higher in 'Ayvaniye' variety. In terms of TPC and b* parameters, 'Granny Smith' variety was better. Additionally, the flesh firmness of 'Granny Smith' variety was higher at the beginning of storage. When all parameters were evaluated, 'Ayvaniye' variety is more suitable for cold storage for 6 months, but weight loss may be a problem for storage longer than 6 months.
