Orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. Intensification is possible by using dwarfing rootstocks that control tree size, induce early cropping, and produce large quantities of fruit relative to the amount of wood produced. Therefore, this study attempts to compare some yield and fruit properties of five apple cultivars grown in the Karaj area of Iran. The concerned apple cultivars were Golab-kohans (Iranian cultivar), Fuji, Starking, Delbar estival and Prime rose (commercial foreign cultivars) that were grafted on M.9 rootstock which were trained in Geneva Y-trellis system. All of these trees were planted in winter 2004. The trees were irrigated from the second year after planting and the method of irrigation was drip irrigation. pH (4.07) and Humidity Content (85.96 %) were the highest with the Golab-kohans (Iranian cultivar). Also Delbar estival had the highest fruit length (6.13 cm), L/D (0.87) and TSS (15.77). Starking had the highest fruit weight (145.24 gr), fruit diameter (6.91 cm) and Ash (0.71 %). In addition, the most dry matter (20.13 %), fruit firmness (13.13 kg/square cm) and titrable acid (0.72 %) were recorded with Fuji.
