| Abstract: | 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. |
