摘要： [目的]筛选抗白粉病月季资源对月季栽培利用及抗病育种品种的选择有重要意义。[方法]对保存的来自国内外不同地区、不同类型的349份月季资源进行了田间筛选。供试品种病情分为高抗、抗病、中抗、感病、高感5个等级。[结果]供试品种对月季白粉病抗性表现比较分散。月季抗病资源182份,占供试品种的52.15％,其余167份均表现为感病,占47.85％,其中抗病资源中有13份表现为高抗,占供试品种的3.72％；349份资源中包括27份中国古老月季,其中有11份表现为抗病,占中国古老月季的40.74%。[结论]抗白粉病月季资源的筛选能够为月季栽培、育种亲本品种的选择提供参考。

Abstract: It is very important to screen resistance resources to rose powdery mildew for screening cultivation varieties and resistance breeding in rose. In this study, 349 rose cultivars were screened, which were derived from different regions and types. All the rose resources were classified into 5 levels including high disease resistant, disease resistant, middle disease resistant, susceptible and highly susceptible according to the survey. The results indicated that the resistance to rose powdery mildew was diversified. 182 accessions of rose resources were disease resistant, accounting for 52.15% , and other 167 accessions were susceptible, accounting for 47.85%. In addition, 13 accessions showed high resistance (3.72%). 27 accessions of all the 349 rose resources were from China ancient rose varieties, of which 11 showed disease resistance, accounting for 40.74% of the varieties. Screening of resistance to powdery mildew in rose resources could provide a foundation for the cultivation and variety breeding of rose.
