摘　　要：对中国南北方大豆品种和新品系进行抗灰斑病鉴定,旨在为抗病育种提供优良抗源和挖掘新的抗病基因。大豆生育期进入R3～R4阶段对593份大豆材料进行人工接种灰斑病菌。结果表明:北方高抗材料比例明显高于南方材料;在高抗材料中品种所占的比例明显高于品系和资源,抗病材料中资源所占的比例高于品种和品系;不同区域品种、品系均有抗灰斑病的材料;高抗和抗病品种为92份,高抗和抗病品系为57份。对200份材料多生理小种鉴定结果表明有55份材料抗5～10个生理小种,其中抗5～7个生理小种的材料为48份。南北方大豆资源中均有抗灰斑病的材料,北方高抗材料比例明显高于南方材料,抗病材料南北方持平。We identify soybean cultivar and new strain resistant toCercospora sojina in the south and north of China to supply good anti-disease resource for breeding for disease resistance and discover new disease-resistant genes. When the soybean goes into state R3 to R4 of its child-bearing period, we evaluate and appraise the resistance of 593 portions of soybean resource proceeding under artificial infection condition. The results showed that the proportion of high resistant material in the north was much higher than that in the south. Moreover, in the highly resistant resources, the proportion of cultivar was obviously higher than that of strain and resource, and the proportion of disease-resistant resources was higher than that of cultivar and strain. The resisted Cercospora sojina was exist in different areas, highly resistant and disease-resistant cultivar was 92 portions and highly resistant and the disease-resistant strain was 57 portions. The results from 200 materials of multi- physiologic seeds showed that there were 55 materials had the ability to resist 5-10 physiologic seeds, and 48 materials to resist 5-7 physiologic seeds. There were materials resistant to Cercospora sojina in the soybean resource from both south and north. The portion of high resistant material in the north was much higher than that in the south. Disease-resistant materials are almost the same between south and north.
