【摘要】 <正> 长期以来,葡萄只是作为一种北方果树在我国北方几个省区大面积栽培。江西是靠近东南沿海的心腹地区,这种特殊的地理位置和地形条件,构成了冬冷春凉、夏热秋燥、春夏多雨的季风性温热多雨气候。由于我省4—6月高温多湿,而此时正是葡萄枝叶发生,各种营养器官和生殖器官尚幼嫩的时期,引入的大多数欧洲种品种品质虽好但黑痘病发生极其严重,以致管理成本高,经济效益低。引入的美洲种及其杂种、虽抗病性较强,但品质较差。因此,根据我省特点,选育出适应高温多湿的生态环境,能抗黑痘病和其它真菌性病害又能获得丰更多还原

【Abstract】 Baimeikan、Zimeikan and Meiyehei are three new strains of grapes selected through sexual cross. This paper deals with their parents and traits. Baimeikan is the first generation of the cross breed between Muscat Hamburg as the ovule parent and Campbell Early as the pollen parent This strain resists strongly against diseases, yields highly, ripens in the early August and possesses good quality. Zimeikan is selected from the different individuals of the same cross as Baimeikan. Its resistance against diseases is comparatively strong and its yield is high. It is harvested in late July and has the same quality as Baimeikan. Meiyehei is the offspring of poly—cross among Muscat Hamburg, Vitis flexuosa Thunb and Black Hamburg. It is free from Sphaceloma ampelophagum. It produces more fruits with ruddy color. It may be used in making wine or as an stain. All of these strains can endure hot and damp weather.更多还原
