Abstract: 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 grafting 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。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.
