Clonal rootstock selection suitable for apricot cultivars 'Hacıhaliloglu' and 'Kabaası'
Hacıhaliloğlu and Kabaaşı are the most widely grown dried apricot cultivars in the world. Trees of these cultivars develop fairly well. In the Malatya region of Turkey, apricot trees are planted at 10×10 m and, in some areas, 12×12 m. Difficulties in cultural practices such as harvesting and pruning, low yield rate for per unit area, long juvenile period and, in particular, the presence of a high losses in quality during harvesting, require the use of dwarf rootstocks in apricot breeding. To determine the most suitable rootstock for these cultivars, Pixy, Myrobalan GF-31, Myrobalan 29 C, Marianna 2624, GF-677, Adafuel, Citation, Kayısı Erigi, G×N and seed rootstock (Tokaloğlu Erzincan) were used. In this study, the dense planting possibilities of Hacıhaliloğlu and Kabaaşı and graft compatibility between these apricot cultivars and rootstocks used in the study were examined. Graft incompatibility occurred between the Hacıhaliloğlu and Adafuel, Citation, GF-677 and G×N rootstocks and between Kabaaşı and Citation and GF-677 rootstocks. Of the rootstocks suitable for the two apricot cultivars, Pixy and Marianna 2624 showed dwarf development, while Myrobolan 29-C, Myrobolan GF-31, Kayısı Erigi and Tokaloglu Erzincan showed strong development.
