辽宁省的的葡萄生产,近十几年来发展很快,但品种构成不尽合理,中熟品种居多(主要为巨峰),占90%以上;早熟品种偏少,只占3%。目前生产上的早熟品种主要是乍娜和康太,虽属大粒,但因乍娜抗病力差,康太品质不佳,需要选育或引进更好的品种。1984年我省直接从日本引进了蜜汁葡萄(奥林匹亚×Fre-doniar4×,欧美杂种,泽登晴雄育成)。我们于1985年—1987年对其主要特征特性等进行了观察。又于1988～1990年以康太为对照进行了品种比较试验。1990年在东北三省的协作下建
The grapes production in Liaoning Province has developed rapidly in recent ten years. However, the composition of grapes is not reasonable. The majority of middle-maturing varieties (mainly Jufeng) account for more than 90% of the total. Premature varieties are only 3% less. At present, the production of early maturing varieties are mainly Zha na and Kang Tai, although a large grain, but due to Zacha’s poor disease resistance, the poor quality of the Conch, breeding or the introduction of better varieties. In 1984, our province directly imported honey grapes (Olympia × Fre-doniar4 ×, European and American hybrids, Zentai Qingxiong bred) directly from Japan. From 1985 to 1987, we observed the main characteristics and so on. In 1988 ~ 1990 Kangtai for the comparison of varieties tested. Built in collaboration with the three northeastern provinces in 1990
