为了筛选西藏青稞抗白粉病资源，选取具有代表性的330份青稞材料在田间进行白粉病感染调查，结合室内盆栽幼苗接种鉴定。330份青稞材料的鉴定结果表明，田间发病大多是中下部叶片感染，发病材料169份，占供试材料的51.21%；室内幼苗接种发现高抗材料7份，占供试材料的2.12%，抗病材料12份，占供试材料的3.64%，感病和高感品种311份，占供试材料的94.24%。
為瞭篩選西藏青稞抗白粉病資源，選取具有代錶性的330份青稞材料在田間進行白粉病感染調查，結閤室內盆栽幼苗接種鑒定。330份青稞材料的鑒定結果錶明，田間髮病大多是中下部葉片感染，髮病材料169份，佔供試材料的51.21%；室內幼苗接種髮現高抗材料7份，佔供試材料的2.12%，抗病材料12份，佔供試材料的3.64%，感病和高感品種311份，佔供試材料的94.24%。

In order to screening powdery mildew resistance resources of Tibet hulless barley,330 representative barley materials were selected to investigate the infection of powdery mildew in Lhasa field,which was also identified through indoor seedling inoculation. The results showed that mostly it was leaves at middle and lower position got infected by the powdery disease with 169 materials infected out from 330,which account for 51. 21% among the testing materials. By means of Indoor Seedling Inoculation,7 highly resistant ma-terials,which account for 2. 13%;12 resistant materials,which account for 3. 64%;311 kinds of high susceptible varieties,which account for 94. 24% were found out.
