This study was carried out in the greenhouses of the Eastern Mediterranean Transitional Zone Agricultural Research Institute in 2019 to investigate rooting situation of clonal rootstock candidates belonging to different species of Prunus obtained by selection breeding from Kahramanmaraş natural plantation. In the study, 28 rootstocks were usedfrom P.cerasifera, P.domestica, P.divaricata and P.persica. GF 677 (P. persica × P. amygdalus) Myrobolan 29C (P. cerasifera) and Pixy (P. institia) were used as control rootstocks. In the experiment, 0- 1000- 2000- 3000 mg L-1 IBA (Indolbutyric acid) and medium size perlite were used. As a result of the study, the highest rooting percentage was obtained from P. persica with 98.07% and the lowest from P. divaricata with 74.19%. The highest number of roots was determined in P. persica (9.14 pieces/cutting) and the lowest number of roots was found in P. divaricata (3.19 pieces/cutting). Among all clones used in the study, 100.00% rooting was detected in six candidate clonal rootstocks (KL-20, KL-12, KL-21, KL-24, KL-27, KL-23). The highest mean root number was found in clone KL-27 (P. persica) with 14.91, and the highest root length was found in KL-59 (P. cerasifera) with 64.82 mm. At the end of the study, although rooting results are better in rootstocks of P. persica species, despite lower results in rootstocks of P. divaricata species, it was found interesting that the best clonal rooting result was in the clone of P. domestica which 1000 mg. L-1 and 2000 mg.L-1 dose IBA applications gave the best results according to both rooting rates and average root length values.
