Apple (Malus domestica Borkh.) is one of the most economically important pome fruits worldwide and Turkey. Domesticated apples have been cultivated since ancient times and are now produced in a range of area from Siberia with freezing temperatures to some equatorial locations with high temperatures. Using rootstock is one of the most important factors in apple cultivation and adaptation to stress conditions. Rootstock also affects yield and fruit quality. In this study, the effects of dwarf and semi-dwarf rootstocks on different apple cultivars were investigated in Kayseri-Turkey conditions. Three rootstocks (M9, M26, MM106) and four apple cultivars (Braeburn, Granny Smith, Spur Golden, Starking Delicious) were used in the study. The plants used in the study are 4 years old. Rootstocks effects of yield, fruit weight, fruit lenght, fruit width and total soluble solids of apple cultivars were investigated. Tehere were significant differences for investigated characters except fruit width among studied rootstock/scion combinations. Braeburn/M9 combination was the best one for yield (23.4 kg/tree) whereas Starking/M9 had the lowest value (10 kg/tree. Fruit weight of combinations ranged between 169.6 (Granny Smith/M26) and 196.7 g (Spur Golden/M26). This study conducted that rootstocks effected (positively or negatively) yield and fruit quality of apple cultivars.
