甜黄魁是我所果树育种研究窒1963年利用祝光(Summerpearmain)×黄魁(yellvw transparent)杂交培育的半矮化苹果品种,其植株矮小,树冠大小近似M7,树高一般为3.0～3.5米,枝条生长较直立,不易开张,节间短,短枝比例多,易形成腋花芽,结果较早,一般情况下2～3年生幼树就能开花结果。果实形状、频色及大小似黄魁,6月下旬至7月上旬成熟。为了研究甜黄魁中间砧对嫁接品种生长发育的影响,于1974年春、夏季,在甜黄魁一年生苗木上(根砧为山定子)分别嫁接了锦红、 Sweet yellow Quebec is my fruit tree breeding research stifled in 1963 by the use of light (Summerpearmain × yellvw transparent hybrid cultivating semi-dwarf apple varieties, the plant is short, the approximate crown size M7, tree height is generally 3.0 to 3.5 Rice, branches grow more upright, not easy to open, internodes short, short stub ratio, easy to form axillary buds, the results earlier, under normal circumstances 2-3 years can plant saplings. Fruit shape, color and size like Huang Kui, late June to early July mature. In order to study the effect of sweet and koji intermediate anvil on the growth and development of grafted varieties, in spring and summer of 1974,
