目前,在我国特早熟毛桃品种中,由于果实发育期较短,果个偏小,品质较差,产量较低,着色差,口味淡,硬度低,不耐贮运,因此,限制了特早熟桃的发展。选育果个大、品质上等、果实较硬,市场货架期较长、着色好、丰产稳产的特早熟桃品种就成为我们果树研究所的主要目标。一、主要性状1.1 物候期:早春硬蜜桃3月16～20日花芽萌动,3月29日～4月2日初花,4月6日左右为盛花期,4月10日左右为展叶期,5月25日前后果实着色,6月5日果实成熟上市,果实发育期为58d(天), At present, our country special early peach varieties, due to the short development period of fruit, fruit is too small, poor quality, low yield, poor color, light taste, low hardness, impatience storage and transportation, thus limiting the special precocious Peach development. Breeding fruit big, first-class quality, hard fruit, the market shelf life is long, good coloring, high yield and stability of peach varieties have become our fruit trees Institute of the main objectives. First, the main traits 1.1 phenophase: peach early spring March 16 to 20 bud germination, March 29 ~ April 2 early flowering, April 6 or so for the flowering stage, April 10 or so for the exhibition leaf The fruit is colored before and after May 25, the fruit is ripe and listed on June 5, the fruit development period is 58 days (days)
