湿热地区不同葡萄品种对黑痘病的抗性分析

Study on the Anthracnose Disease Resistance of Different Varieties of Grape Cultivar in Hot and Humid Southern China

采用田间自然鉴定的方法,研究分析了湿热地区28个葡萄栽培品种、7个毛葡萄野生株系对黑痘病的抗性差异。结果表明,欧亚种品种对黑痘病较感病,大部分品种对黑痘病表现为高感;欧美杂交种品种,大部分表现为抗病,有的甚至高抗;毛葡萄与欧亚种的杂交后代属于高抗病品种;而毛葡萄野生株系对黑痘病均表现为免疫。

To study the Anthracnose disease resistance of different varieties of grape cuhivar,28 Grape cultivar,7 wild species of V. quinquangularids Rehd were used for studying to anthracnose disease （Sphaceloma ampelinum de Bary）by natural infection in field conditions. Results showed that V. viniera was susceptible or high susceptible to it; the hybrids of V. vinifera ＆ V. labrusca was resistible or high resistible to it; the hybrids of V. quinquangularis Rehd ＆ V. vinifera was high resistible to it; the wild species of V. quinquangularis Rehd was immune to it.
