摘　　要：通过7年芽变筛选,在地方短枝杏的基础上,增加嫁接群体数量提高了变异概率,筛选出龙田黄杏(编号DV-2)矮化杏树新品种。该品种树体矮化或半矮化,树高为对照的61.3%～65.7%;同时早花早果明显,定植后第2年普遍结果,第4年进入盛果期;果实发育期68 d左右,在山西省中部地区6月中旬成熟。After 7-year systematic investigation and observation, a dwarf apricot variety Longtianhuangxing（DV-2） has been newly selected from a spur tape apricot variety in south Shanxi. As a dwarf and/or half dwarf tree, the height of tree is about 61.3%-65.7% of its parent. The flower bud on young tree is easily developed. New variety begins to fruit in the second year and produce full yield around the 4th year. As a middle ripening variety its fruit developing duration is about 68 days.
