综述了近年来在玉米抗叶斑病基因染色体定位方面的研究概况及发展动态 ,并就分子生物学方法对玉米叶斑病的数量性状位点(QTL)的作用做了较详细的介绍 ,例举了已定位的抗叶斑病的质量性状和数量性状控制的基因位点及其在抗病中的作用 ,而且对玉米抗叶斑病基因定位后克隆在抗病育种中的应用做了展望
In this paper, the research status and development trends of chromosomal mapping of maize leaf spot resistance genes in recent years are reviewed. The role of molecular traits in quantitative trait loci (QTLs) of maize leaf spot disease is described in detail. The genetic loci controlled by QTLs and QTLs for resistance to leaf spot disease were put forward and their roles in disease resistance were also illustrated. Moreover, the prospect of the application of maize anti-leaf spot loci in resistance breeding was prospected
