摘　　要：通过对28个玉米品种进行田间强致病力菌株接种,鉴定了其抗病性。结果表明:不同玉米品种对玉米小斑病的抗病性存在差异,28个玉米品种中大多数玉米品种属于抗或者高抗水平;只有冀玉12号、鲁单9056、郑单958和先玉335属于中抗品种,而这些品种推广面积较大,是玉米主产区的主流品种,建议严密监测小斑病菌的致病性,尽快筛选对强致病力菌株抗性好的高产玉米品种。The resistance of 28 maize varieties to virulent strain of southern leaf blight was detected.The results showed that the resistance of different corn varieties was different,most varieties were resistant or highly resistant to the strain.Jiyu No.12,Ludan 9056,Zheng 958 and Xianyu 335 were moderately resistant to the strain,and they were also the main varieties in maize production area with large area.The pathogenicity should be closely monitored,and the high yield varieties resistant to virulent strain should be screened as soon as possible.
