摘　　要：对2017—2022年河南省花生联合体区域试验共316份参试新品种(系)进行叶斑病抗性水平综合评价,以期为生产上花生品种布局和病害综合防控提供参考依据。结果表明,2017—2022年间中抗水平以上品种占比10.91%~100%,感病品种占比69.09%~89.09%,其中2021年检测到2个高抗品种,未发现感病品种。6年间均未发现高感品种,说明河南省花生品种历经多年品种更替,对叶斑病的抗性水平已有较大提升。2017—2022年中抗水平以上品种在不同区组占比从高到低依次为小粒组(45.08%)、夏播组(34.25%)、麦套组(31.40%),高抗以上品种仅存在于麦套组,占比为1.70%。筛选出2份高抗材料,可在生产上推广并作为叶斑病抗性育种的基础运用。The leaf spot resistance level of 316 new varieties (lines)tested in the Arachis hypogaea complex regional trial in He'nan Province from 2017 to 2022 wascomprehensively evaluated,in order to provide reference for Arachis hypogaea variety layout and disease prevention and control in production.The results showed that during 2017-2022,10.91%to 100%of varieties were above medium resistance level,and 69.09%to 89.09%of susceptible varieties were detected.In 2021,2 highly resistant varieties were detected,and no susceptible varieties were found.No highly susceptible varieties were found in the six years,indicating that the resistance level of Arachis hypogaea varieties to leaf spot in He'nan Province had been greatly improved after many years of variety replacement.From 2017 to 2022,the proportion of varieties above mid-resistance level in different groupSfrom high to low wassmall grain groups(45.08%),summer sowing groups(34.25%),and Intercropping wheat groups(31.40%),while varieties above high resistance level only existed in Intercropping wheat groups,accounting for 1.70%.Two highly resistant materialSwere selected,which could be popularized in production and used asthe basis for leaf spot resistance breeding.
