摘　　要：本研究对我国４２株土壤杆菌待测菌株和２８株参比菌进行了数值分类和ＤＮＡ同源性分析，结果将４１株土壤杆菌与２株根瘤菌分在３个土壤杆菌种内，其中２３株来自内蒙等地葡萄的菌株分在葡萄土壤杆菌种内，１０株来自山东等地樱桃、桃树的菌株为发根土壤杆菌，８株来自４个地区４种植物的菌株及分自宁夏刺果甘草的２株根瘤菌菌株参比菌分在根癌土壤杆菌种内。１株土壤杆菌和１株根瘤菌的分类地位有待进一步研究。Forty- two Agrobacterial isolates from China and 28 representatives of Agrobacterium and Rhizobium were classified by numerical taxonomy and DNA homogenic analysis.Forty one strains of agrobacteria and two strains of rhizobia fell into three agrobacterial species.Twenty three agrobacteria isolated from grapes in Innermongolia Autonomous Region and other regions were grouped into A.vitis .Ten strains from cherries and peaches in Shandong and other provinces were grouped into A.rhizogenes .Whereas,eight agrobacteria from 4 plants of 4 regions,two new rhizobia from Glycyrrhiza pallidiflora in Ningxia Hui Autonomous Region were placed into A.tumefaciens .The classification status of one isolate of agrobacterium and one of Rhizobium require further investigation.
