Determination of appropriate species and varieties of these species for ecology is extremely important in terms of sustainable and economic production. In the conducted study, the results regarding the local adaptation of three different apple varieties ('Arabian Red', 'Fuji Kiku' and 'Jonagold') grown in Isparta ecological conditions. In addition, correlations among the investigated characteristics were calculated and their potential to be handled together were revealed. Full bloom was first seen in 'Jonagold' (17.04), while' Fuji Kiku' is the latest harvested cultivar (22.09). ‘Fuji Kiku’ has also been identified as the variety that needs the longest time (156 days) to reach harvest ripening. The highest yield per tree was obtained from ‘Arapkızı’ variety with 22.35 kg tree-1, while ‘Jonagold’ was the lowest in terms of this trait with 13.68 kg of tree-1. Among the pomological characteristics fruit width, length and weight were lowest in ‘Fuji Kiku’ and highest in ‘Jonagold’ varieties and these properties were found in the range of 66.44–73.17 mm, 55.52–63.34 mm and 134.11–183.11 g, respectively. While a negative correlation was determined between yield with fruit length (-0.33) and weight (-0.19), positive correlations were determined with the same properties and the upper shell a colour, titratable acidity, and day from full blooming to harvest. In line with the obtained results, it can be said that the most suitable cultivar for high density planting is 'Arapkızı'. On the other hand, 'Jonagold' variety stands out in terms of fruit sizes, weight and color values.
