采用黄化苗下胚轴接种法,利用大豆疫霉菌株Pm8对来自不同地区的355份大豆品种(系)进行疫霉根腐病接种鉴定.结果表明:96份材料表现为抗病类型,占鉴定总数的27%,106份表现为中间类型,占总数的30%.在所鉴定的品种(系)中,北京、浙江等省(市)抗大豆疫霉菌株Pm8的资源比较丰富;吉林、四川等省的抗性资源较贫乏.研究结果为大豆抗病育种选择亲本和利用品种布局进行大豆疫霉根腐病生态控制提供了依据.

Phytophthora root rot caused by Phytophthora sojae is a destructive disease for soybeans[Glycine max(L.)Merr.] throughout the soybean production regions.Utilization of resistant varieties is the most economical and environmentally safe method for controlling disease.Three hundred and fifty-five soybean cultivars or lines from different areas were evaluated for their responses to strain Pm8 of P.sojae using the hypocotyls inoculation technique to the etiolated seedlings.Of all cultivars or lines,96 were resistant and 106 were intermediate to Pm8.The resistant resources to Pm8 from Beijing and Zhejiang Provinces were rich,while Jilin,Sichuan Provinces were poor.The results of the study provided the useful information for breeding of resistant variteties and ecological control for Phytophthora root rot.
