摘　　要：利用苹果属野生砧木资源晋西北山定子实生选育苹果矮砧,从嫁接苹果品种成苗中选出当年形成花芽、第二年开花的植株571株,其中有325株当年结果,暂定名为Y系。并对树体开花、结果、生长量、越冬表现等项目的田间调查与综合评价,经过5年的工作现已初选出80个优系。初步试验表明,Y系苹果砧木抗逆性强,早花早果特性极为突出,嫁接栽培品种亲和性好,部分单系矮化性状明显,具有广阔的应用前景。By selecting dwarfing apple rootstocks from Malus baccata（L.）Borkh, in Northwest-Shanxi,which is a wild Malus rootstock resource, we chose 571 plants among the mature seedlings of gaffing apple varieties, which form flower buds in the same year and can bloom the next year. Among these, 325 plants can bear fruit in the same year it is planted, which we named ＂Y series＂ temporarily. In addition, we carried out field investigation and synthetic evaluation on blooming, fruiting, the amount of growth, as well as the over-winter performance of these plants o After 5-year hard work, we have preliminarily selected 80 major cliques. As the preliminary test shows, Y series of apple stocks have a strong resistance, an outstanding habit of early-blooming and early-fruiting, a good compatibility of varieties after grafting. Some single cliques have a distinct trend of dwarfing, which brings it a bright application future.
