As the rapid variation and mutation of the races of Exserohilum turcicum (Helminthosporium turcicum), maize varieties lost their resistance to northern corn leaf blight (NCLB) disease caused by new races of E.Turcicum. This brought the disaster in maize production.Up to now 5 races have been found. The maize resistance to E.turcicum can be divided into quantitative and qualitative resistance, the former is associated with 10 chromosomes in maize,and the later includes genes of t1, Ht2, Ht3 and HtN. The race variation of E.turcicum,the original gene resources and genetic characteristics of each Ht monogenic resistance,the chromosome location of t1,Ht2, HtN genes, and the QTL analysis of quantitative resistant genes for E.turcicum in maize were reviewed in this paper.
由于玉米大斑病菌（大斑凸脐蠕孢菌）生理小种的快速变异和突变，玉米品种对由新的玉米大斑病菌生理小种引起的玉米大斑病失去了抗性。这给玉米生产带来了灾难。到目前为止已发现5个生理小种。玉米对玉米大斑病菌的抗性可分为数量抗性和质量抗性，前者与玉米的10条染色体有关，后者包括t1、Ht2、Ht3和HtN基因。本文综述了玉米大斑病菌的生理小种变异、各Ht单基因抗性的原始基因资源和遗传特性、t1、Ht2、HtN基因的染色体定位以及玉米对玉米大斑病菌数量抗性基因的QTL分析。
