摘　　要：对北京市主要栽培的72个芍药品种感病情况进行了调查与病原鉴定,主要鉴定出红斑、灰霉、轮纹、炭疽4种真菌性病害,室内鉴定其病原菌分别为枝孢属、灰葡萄孢属、拟盘多毛孢属以及盘圆孢属。2009-2010连续2年采用田间调查方法鉴定了不同芍药品种对4种芍药常见病害的抗性,分别制定出不同病害的抗性分级标准。结果表明,2009年供试的72个品种对不同病害的抗病性有显著差异,供试品种对炭疽病害抗性较强,平均病情指数在20以下的有68个,占调查总品种的94.44%;对灰霉、轮纹、红斑病害达到抗病水平的比例分别为66.67%、55.56%、62.50%。2010年的调查结果表明,2009年所筛选出的10个抗病品种英雄花、金星闪烁、擎天红、美菊、紫红魁、绚丽多彩、艳阳天、蓝田碧玉、种生粉、桃花飞雪,抗性较为稳定,为优良品种。Survey and pathogen identification of diseases on 72 varieties of herbaceous peony in Beijing were observed,four main fungal diseases were identified,including red spot,gray mold,round spot and anthracnose,and pathogens were identified indoor,including cladosporium,Botrytis sp.,Pestalaiopsis spp.and Gloeosporium.The resistances of herbaceous peony varieties to four main fungal diseases were tested in 2009 and 2010,and the criteria of peony disease classification was developed.The resttlt showed that the differences of resistance to four diseases among these varieties were very observable in 2009.68 herbaceous peony varieties of resistance to anthracnose had a low disease index below 20 with the frequency of 94.44 ％ ; Varieties of peony resistance to red spot,gray mold and round spot achieved to resistance level,with the frequency of 66.67 ％,55.56 ％,62.50 ％.In 2010,statistics showed that ten of these varieties,including ‘ yingxiong hua＇,‘jinxing shan shuo＇ et al.,were resistant varieties with a lower disease index.
