摘　　要：大豆根腐病、疫霉病和胞囊线虫病是生产上极难防治的土传病害,目前有效的防治措施就是种植抗病品种,抗病种质的筛选鉴定是抗病育种的基础。本研究针对这3种病害进行抗病性鉴定,为抗病育种提供良好的单抗和多抗资源。用人工接种鉴定的方法,对76份大豆材料分别接种大豆尖孢镰刀菌、大豆疫霉菌1号生理小种和胞囊线虫3号生理小种,进行单一病害鉴定,按各病害的抗性评价标准对每份大豆种质资源进行抗性评价。共计筛选出抗根腐病材料11份,抗疫霉病材料13份,中抗大豆胞囊线虫材料9份。中抗及抗两种病害的品种(系)有6份,占鉴定总数的7.9%;同时对3种病害表现中抗以上的材料只有1份,占鉴定总数的1.3%。研究结果将为新品种培育和抗病基因挖掘提供理论依据。Soybean root rot,Phytophthora and cyst nematode are the major soil-borne diseases that are extremely difficult to control.Planting resistant varieties are effective measures,and screening of resistant germplasm is the basis of breeding resistant varieties.76 soybean materials were inoculated with Fusarium oxysporum,race 1 of Phytophthora sojae and race 3 of cyst nematode respectively.The resistance of each soybean germplasm was evaluated according to the resistance evaluation standard of each disease.A total of 11 anti-root rot materials,13 anti-Phytophthora materials,and 9 materials with moderately resistant soybean cyst nematode were screened out.6 varieties(lines)were resistant to two diseases,accounting for 7.9%.Only 1 material was resistant to the above three diseases,accounting for 1.3%.The results will provide a theoretical basis for the cultivation of new varieties and Identification of disease resistance genes.
