    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;只抗其中一种病害的自交系82个;兼抗两种病害的有61个,兼抗三种病害的自交系有28个,兼抗四种病害的自交系有4个。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三种生态类群间,以及四种叶球抱合类群间的抗病性表现出明显差异。

    Abstract:

    Resistance to downy mildew, Turnip mosaic virus (TuMV), black rot, verticillium 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 lines 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 ones 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, 11-234, 04-622, 12-85, 13-108 and 09-894, were elite materials for disease resistance breeding. In addition, the difference of disease resistance was observed among three types of Chinese cabbage for spring, summer and autumn cultivation, which also existed among four heading types.
