【摘要】 对九个葡萄品种 4次田间抗黑痘病调查 ( 6月 10日 ,6月 2 0日 ,7月 11日 ,9月 2 2日 )的结果表明 ,各品种 (系 )的抗病性存在一定差异。按照果实的感病指数可将供试品种归为三类 :88 0 3 ,88 0 4为高感品系 ;爱格丽、88 0 2为中感品种 (系 ) ;北醇、西拉、白克列海特为低感品种 (即高抗品种 )。综合叶果感病率及感病指数的结果 ,供试品种中以白克列海特抗病性最强更多还原

【Abstract】 The resistance of 9 cultivars to anthracnose disease (Sphaceloma ampelinum de Bary) was studied by 4 times natural infection investigation in field conditions. The results showed that there were some degree differences of disease resistance among investigated cultivars. According to the disease indexes of fruits, the experimental varieties were divided into 3 different classes:88-03 and 88-04 had weak resistance to the disease; Ecolly and 88-02 had secondary resistance, and Beichun,Syrah and Mauzac had strong resistance. On the basis of disease incidences and the disease indexes of fruits and leaves, Mauzac’s resistance to the disease was the strongest among investigated varieties.更多还原
