Abstract: This research was done with aim of determine the most suitable scion source, the best grafting height and the most suitable budding methods on Mahaleb rootstock. This study was performed during the summer season of 2013 at Nursery in Marbin region of Isfahan. The two cultivars of sweet cherries (white and black) was used as scion and Mahaleb seedling was used as rootstock. The treatments consisted of two cultivar of sweet cherries (white and black), three budding methods (T with and without wood budding and chip budding) at three different height (10-12, 20-25 and 30-35 cm) above ground. The experiment was laid out in a split plot randomized complete block design with three replications. All treatments were found to be suitable for sweet cherry propagation. However, the shortest time of bud take and earlier sprouting time were obtained with T-budding with wood performed at 10-12 cm above ground. The highest mean shoot length is obtained with black sweet cherry scion with T-budding with wood at 10-12 cm above ground. The most number of leave were obtained with black sweet cherry scion with T-budding with wood performed at 30-35 cm above ground. The most number of lateral shoot were obtained with white sweet cherry scion with T-budding with wood performed at 20-25 cm above ground. T-budding with wood was significantly more successful than two other methods. Also budding at 10-12 and 20-25 cm above ground had been best results and scion of black sweet cherry was be most suitable as scion for Mahaleb rootstock.
