我所于８０年代引进苹果ＣＧ系矮化砧本主要型号，经１０余年多点试验研究，结果表明：以ＣＧ系矮化砧木作中间砧嫁接苹果品种，嫁接亲和。幼树生长快，树体矮化，品种结果早，果实品质与对照Ｍ２６作中间谐相近。筛选出的ＣＧ８０是当前苹果理想矮化砧木。
I introduced the main model of Apple CG dwarfing anvil in the 1980s. After more than 10 years of experimental research, the results showed that grafting of apple varieties with CG dwarfing rootstocks as the intermediate anvil was grafted and grafted on. Saplings grow fast, dwarf trees, early varieties results, fruit quality and control M26 for the middle harmonic similar. The selected CG80 is the ideal apple dwarf rootstock.
