采用孢子悬浮液喷雾接种法（孢子浓度为1×104个/mL），选择分离自靖远县日光温室罹病黄瓜茎和叶片的2个多主棒孢霉（Corynespora cassiicola）菌株，对白银地区市售的15个黄瓜品种进行了黄瓜褐斑病抗性鉴定。结果表明，测试的15个品种中，津旺68表现高抗，津棚A2、津典303、津优312、津棚A1、碧丽1号、SV1102CC表现抗病，建议在白银地区优先选用。
採用孢子懸浮液噴霧接種法（孢子濃度為1×104箇/mL），選擇分離自靖遠縣日光溫室罹病黃瓜莖和葉片的2箇多主棒孢黴（Corynespora cassiicola）菌株，對白銀地區市售的15箇黃瓜品種進行瞭黃瓜褐斑病抗性鑒定。結果錶明，測試的15箇品種中，津旺68錶現高抗，津棚A2、津典303、津優312、津棚A1、碧麗1號、SV1102CC錶現抗病，建議在白銀地區優先選用。

In order to provide reference for local cucumber growers choosing cucumber varieties,15 commercially available cucumber varieties collected from Baiyin area have carried out the cucumber brown spot resistance evaluation. Two strains of Corynespora cassiicola be used in this test,which are isolated from diseased cucumber stem and leaf at sunlight greenhouse in Jingyuan county . Conidia suspension (conidial concentration is 1×104/mL)is sprayed on cucumber seedlings with 2 true leaves. The result shows that Jinwang 68 is highly resistant,Jinpeng A2,Jindian 303,312 Jinyou 312,Jinpeng A1,Bili 1,SV1102CC are resistant. Finally, suggestions on Baiyin area should be selected in preference.
