苹果矮化砧木——辽砧2号

A New Dwarf Apple Rootstock—‘Liaozhen 2’

‘辽砧2号’是从‘助列涅特’בM9’杂交实生苗中选育出的苹果优良矮化砧木,经过22年的室内和田间调查及区试鉴定,其矮化性、早果性、丰产性、生根性与‘M26’相近,抗寒性强于M26,与基砧山定子和生产上主栽的富士、国光、岳帅等苹果品种亲合性良好,3年结果,5年生产量22500kg/hm2。

Liaozhen 2’,a promising dwarf apple rootstock,was derived from the cross of M. Pruniforlia×M 9. The results of 22-year investigation show that its characters of dwarf, precocity, productivity and rooting ability are similar to M 26 .The cold hardiness of‘Liaozhen 2’is stronger than that of M 26 .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/hm 2 in the fifth year.
