| 摘 要： | 为发现抗白绢病的抗源材料，以花生28个种质为材料，在阳逻和武昌两地开展了白绢病抗性鉴定，并在温室条件下对其中11个材料进行抗性检测。结果表明：材料间白绢病发病率存在显著性差异（P<0.05）；两试点鉴定获得5份中等抗病材料，其收获前死亡率低于30%。在温室接种条件下，2份材料鉴定为中等抗病。综合田间和温室试验结果，中花212和麻阳小子为中抗白绢病材料，为我国首次报道；中花212还兼抗细菌性青枯病。

| Abstract: | Twenty-eight peanut accessions were assessed for resistance to Sclerotium stem rot in two environ?ments, and 11 accessions among them were further evaluated against Sclerotium rolfsii in greenhouse. The results showed that there were significant differences in disease incidence of some accessions (P<0.05).Five accessions re?corded a mortality of less than 30% in two locations, which were categorized as moderate resistant. Two accessions were moderately resistant under greenhouse condition. Zhoanghua 212 and Mayangxiaozi were both moderate resis? tant in the field and under greenhouse conditions, which were first reported in China, and Zhonghua212 was also highly resistant to bacterial wilt caused by Ralstonia solanacearum. |
