Abstract: ‘Liaozhen 2’, a promising dwarf apple rootstock , was derived from the cross of M. Pruniforlia ×M9.The results of 222year investigation show that its characters of dwarf , precocity , productivity and rooting ability are similar
to M26. The cold hardiness of ‘Liaozhen 2’is stronger than that of M26. The grafting compatibility with Malus baccata(L. ) , and commercial apple cultivars (Fuji , Ralls , Yueshuai , etc) is good. The trees on‘Liaozhen 2’begin to fruit
in the third year and the yield will reach 22500 kg/ hm2 in the fifth year.
