: Apomictic apple rootstock 'Qingzhen 1' is obtained by a traditional hybridization breeding approach in 1999. Its maternal and paternal parents are apomictic crabapple 'Pingyitiancha' (Malus hupehensis Rehder)and columnar apple strain 'CO' (Malus x domestica Borkh. ), respectively. 'Qingzhen 1' tree is gentleness with a columnar habit. Its apomictic fruit setting ability is high up to 97.0% - 98.1%, and therefore it propagated with seeds. The population of one-year-old ' Qingzhen 1' seedlings are uniform in apperance, dwarf in stature and vigorous in growth. As rootstock, the seedlings of 'Qingzhen 1' had a good compatibility with scion cultivars, such as 'Gala', 'Fuji' and 'Jonagold' . As a result, the grafted tree exhibited high resistance to apple branch ring rot and re-plant disease, as well as early flowering, increased fruit yield and good quality. To sum up, ' Qingzhen 1' is suitable to use as apple rootstock in the main production region for apple industry around Bohai Bay and Loess Plateau.
