Abstract: A new cherry rootstock cultivar，‘Mahaleb CDR-2’，was developed by crossing‘Mahaleb CDR-1’，used as the female parent，with steppe cherry（Prunus fruticosa）as the male parent. This rootstock exhibits vigorous growth，strong sprouting and branching abilities，as well as resistance to crown gall and salt tolerance. It also demonstrates early fruiting and high yield potential，along with high grafting compatibility with major domestically cultivated cherry cultivars. Compared to its female parent，‘Mahaleb CDR-1’，it possesses enhanced dwarfing ability and a superior dwarfing effect，making it suitable for cultivation in regions such as Weibei，Guanzhong，southern Shaanxi，Gansu，Shanxi，Henan，Xinjiang，Liaoning，and other similar areas.
