采用新鲜薯块接种法对甘肃省14个主栽马铃薯品种的炭疽病、枯萎病、束梗孢褐腐病和坏疽病抗病性进行了测定。结果表明，供试马铃薯品种上梁红花、陇薯10号、紫花白、定薯1号、大白花、陇薯3号、9810-18对束梗孢褐腐病抗性最强，费乌瑞它和青薯9号抗性最弱。品种定薯1号、L7、庄薯3号对坏疽病抗性最强，青薯9号抗性最弱。品种紫花白和定薯1号对炭疽病抗性最强，新大坪和中薯9抗性最弱。新大坪、庄薯3号、青薯9号、9810-18、陇薯3号、陇薯10号、大白花、中薯9、紫花白、上梁红花、定薯1号、陇薯6号对枯萎病抗性最强，费乌瑞它抗性最弱。综合分析定薯1号、大白花、紫花白、陇薯10号、上梁红花、陇薯6号、庄薯3号和陇薯3号适宜在贮藏期病害发生较重地区推广种植。

The resistance of main cultivation potato varieties in Gansu province for 4 kinds of diseases was identified through the fresh potato piece inoculation method. The result shows that among all tested 14 potato cultivars， the resistance of Shanglianghonghua， Longshu 10， Zihuabai， Dingshu 1， Dabaihua， Longshu 3， 9810-18 are the strongest for potato brown rot disease (Stysanus stemonitis) and Feiwuruita and Qingshu 9 are the weakest. The resistance of Dingshu 1，L7 and Zhuangshu 3 are the strongest for potato gangrene disease(Phoma foveata) and Qingshu 9 the weakest.The resistance of Zihuabai and Dingshu 1 are the Strongest for potato anthrax (Colletotrichum coccodes) and Xindaping and Zhong 9 the weakest. The resistance of Xindaping，Zhuangshu 3， Qingshu 9，9810-18， Longshu 3， Longshu 10， Dabaihua， Zhong 9， Zihuabai， Shanglianghonghua， Dingshu 1 and Longshu 6 the Strongest for potato wilt disease (Fusarium tricinctum) and Feiwuruita the weakest. Comprehensive analysis of that The resistance of Dingshu 1、 Dabaihua、 Zihuabai、 Longshu 10、 Shanglianghonghua、 Longshu 6、 Zhuangshu 3 and Longshu 3 are suitable for cultivated area of heavy disease .
