Abstract :This study was conducted in 2023-2024 growing periods to determine the performance of some standard apple varieties grown under the ecological conditions of the Ereğli district in Konya province. The study evaluated the phenological, physical, and pomological characteristics of Golden Delicious, Starkrimson Delicious, Granny Smith, and Fuji apple varieties. According to the results, bud swelling occurred between March 29 and April 13, bud breaking between April 4 and 20, the beginning of flowering between April 9 and 18, full blooming between April 16 and 30, the end of flowering between April 23 and May 7, harvest between September 6 and October 25, and leaf fall between December 6 and 14. The fruit weights ranged from 145 g (Golden Delicious) to 196 g (Fuji), and fruit firmness ranged from 5.44 kg cm⁻² (Golden Delicious) to 7.10 kg cm⁻² (Starking Delicious). Fruit peel color values varied, with L* ranging from 38.42 (Starking Delicious) to 75.81 (Golden Delicious), a* from -5.52 (Golden Delicious) to 27.98 (Starking Delicious), and b* from 11.96 (Starking Delicious) to 47.56 (Golden Delicious). The soluble solid content (SSC) ranged from 9.25% (Golden Delicious) to 11.51% (Fuji), pH values from 3.32 (Granny Smith) to 4.15 (Starking Delicious), and titratable acidity from 0.38% (Starking Delicious) to 0.93% (Fuji). The findings revealed significant differences among the studied cultivars in terms of adaptation to regional conditions, as well as yield and quality characteristics.
