摘　　要：为明确大白菜骨干自交系的抗病性,本研究于2012-2014年,对课题组保存和创制的203个大白菜自交系进行了霜霉病、病毒病、黑腐病、黄萎病和根肿病的苗期抗性评价。结果显示,高抗上述病害的自交系分别有7、9、0、31和12个;仅抗其中1种病害的自交系有82个;兼抗2种病害的有61个,兼抗3种病害的自交系有28个,兼抗4种病害的自交系有4个;其中自交系11-234、04-622、12-85、13-108和09-894综合抗病性最优。此外,春大白菜、夏大白菜和秋大白菜3种生态类群间,合抱、叠抱、拧抱、舒心等不同抱球类型间,以及国内外不同地理来源间的自交系材料,对5种病害的抗性表现存在不同程度的差异。Resistance to downy mildew, TuMV （ Turnip mosaic virus ）, black rot, verticllhum wilt and clubroot were evaluated by inoculation under controlled conditions at seedling stage in 203 Chinese cabbage inbred lines from 2012 to 2014. The result showed that 7 hnes were highly resistant to downy mildew ,9 to TuMV ,0 to black rot, 31 to verticillium wilt and 12 to clubroot. Out of 203 inbred lines,82 showed resistant to only one of these diseases, 62 lines showed resistant to two kinds of diseases,28 lines showed resistance to three disease and 4 lines showed resistance to 4 diseases. The data also showed that inbred lines including 11-234,04-622,12-85,13-108 and 09- 894, were elite materials for disease resistance breeding. In addition, different ecotypes of Chinese cabbages （ springtype, summer- type, and autumntype）, and different headingtypes of Chinese cabbages （ fluffy- type, shallowtype, deep-type, and flat-type, ） ,as well as different Chinese cabbages from distinct regions showed different disease resistance tendencies.
