摘要： The annual extreme lowest temperatures in the apple growing areas of China are -5 to -35 degrees C. Several fruit breeding units, such as Gongzhuling Pomology Institute of Jilin province and Xiongyue Pomology Institute of Liaoning province, have been developing hardy apple rootstock cultivars, by combining the Malling series dwarf rootstocks with hardy small-size apple cultivar or wild Chinese stocks. Presently some new cold resistant dwarf lines (GM256, 63-2-9, 77-42, CX3) have been selected and their grafting compatibility and precocity are being tested in several locations in China. GM-256 was released in 1980 and presently is being used as intermediate stock because it is difficult root and has a shallow root system. Shandingzi (Malus baccata), is another wild apple type which has been used as a vigorous rootstock for apple production in cold districts. Zaai Shandingzi is a new dwarf type mutation of Shandingzi which has potential to replace Shandingzi because it is cold hardy and dwarfing.
