摘要:
黑腐病是影响甘蓝生产的主要病害之一,为了更好地研究该致病菌的致病机制,本研究在全国各地发病田间采集具有典型症状的病害样本,对病原菌进行分离、纯化,并对其形态特征、理化特性和致病性进行分析,同时测定了来源不同的该菌株基因序列,分析其同源性并构建了系统发育树;以Xcc8004为接种菌,采用喷雾法对11份甘蓝种质资源进行黑腐病苗期人工接种抗性鉴定。结果表明:不同来源的黑腐病菌DNA序列存在碱基差异,系统发育分析结果显示相近地区黑腐病菌聚为一类,亲缘关系较近;致病力测试初步表明长江中下游地区收集到的黑腐病菌致病力较强;供试材料均未表现免疫和高抗反应,不同材料的抗病性有明显差异,其中筛选到抗病材料3份,耐病材料3份,感病材料3份,高感材料2份。建立一套有效的黑腐病生理小种划分鉴定方法并筛选高抗黑腐病材料是今后黑腐病抗病育种的重要工作。
