腺枝葡萄与刺葡萄对葡萄黑痘病和霜霉病的抗性

比较腺枝葡萄和刺葡萄2种野生葡萄与红地球、户太8号2个栽培品种对葡萄黑痘病和霜霉病的抗性差异；腺枝葡萄和刺葡萄嫁接不同栽培品种后，通过调查砧穗组合的抗病性，分析腺枝葡萄与其他野生葡萄资源赋予接穗抗病性的差异。结果表明，腺枝葡萄对黑痘病和霜霉病的抗性均较强，刺葡萄抗黑痘病，但不抗霜霉病；嫁接后，刺葡萄作砧木的组合，抗病性明显增强。由此可以认为，腺枝葡萄和刺葡萄均可作为真菌病害抗性育种的资源，刺葡萄可作为砧木育种材料。

Difference in disease resistance to Sphaceloma ampelinum and Plasmopara viticola among two wild grape species (Vitis adenoclada Hand.-Mazz. and Vitis davidii Foëx) and two cultivated varieties (Red Globe and Hutai-8) were compared. By investigating the disease resistance in natural stands, the difference in disease resistance among scions which were grafted by the wild grape species and other wild grape resources were analyzed. Results showed that Vitis adenoclada Hand.-Mazz. were highly resistant to both Sphaceloma ampelinum and Plasmopara viticola. Vitis davidii Foëx showed resistance to Sphaceloma ampelinum, but not to Plasmopara viticola. The resistance was significantly improved when Vitis davidii Foëx was took as rootstock to form scion-rootstock combinations. Thus, Vitis adenoclada Hand.-Mazz. and Vitis davidii Foëx could be both used as resources for breeds with powerful resistance to fungal disease and Vitis davidii Foëx could be used as a source of breeding material for rootstocks.
