'Liaozhen 2' is a promising dwarfing rootstock for apple. It was selected from the F1 progenies of a cross of Malus prunifolia × M.9 made by the Liaoning Research Institute of Pomology, Xiongyue, China in 1980. A 22-year investigation with this rootstock showed that it is dwarfing, precocious, has rooting ability and is productive similar to M26. The cold hardiness of 'Liaozhen 2' was better than that of M26. Grafting compatibility studies of this rootstock with Malus baccata L., and with the major commercial apple cultivars such as 'Fuji', 'Ralls', 'Yueshuai', showed good graft unions. This apple rootstock can also be used as the inter-stem for apple propagation. The outstanding merit of this rootstock is its strong cold hardiness but its resistance to local diseases should be evaluated if this rootstock is to be introduced commercially.
