摘　　要：‘Y-1’是从苹果属野生砧木资源晋西北山定子中实生选育的苹果砧木,通过对树体开花结果、生长量、越冬表现等田间调查与综合评价,结果表明,该砧木作中间砧嫁接品种早花早果特性极为突出,矮化性状明显,抗逆性强,嫁接栽培品种亲和性好,具有广阔的应用前景。‘Y-1’砧木适宜在黄土高原或气候类似的苹果产区栽培。＇Y-1 ＇ apple rootstock was derived from Malus baccata（L. ）Borkh. , a wild Ma/us rootstock resource, in Northwest of Shanxi Province, China. According to field investigation and synthetic evaluation on blooming, fruiting, the amount of growth, as well as the overwintering performance, ＇Y-1＇ had an outstanding effects on grafted apple varieties with early blooming and fruiting, distinct trend of dwarfing, strong resistance, a good compatibility when used as an interstock, which brought it a bright application future. ＇Y-1 ＇ rootstock was adapted to the Loess Plateau or the region with similar climate.
