分子标记辅助选择在玉米抗病和抗虫育种上的应用

Application of Molecular Marker Assisted Selection in Maize Disease Resistance and Insect Resistance Breeding

在我国,玉米的种植面积和产量均超过水稻和小麦,成为第一大粮食作物。同时,玉米也是食品、饲料、化工原料等重要原材料。因此,利用分子标记辅助选择技术(molecular marker-assisted selection,MAS)与常规育种相结合来获得高产、优质、抗逆性强的玉米品种具有重要的意义。概述了常用的分子标记技术以及MAS在玉米抗病和抗虫育种中的应用,同时分析了MAS的局限性,也展望了未来MAS的发展前景和优势,为我国种业企业服务或育种工作提供参考。

The planting area and output of corn both surpass that of rice and wheat and become the largest food crop.At the same time,corn is also an important raw material for food,feed and chemical raw materials.Therefore,it is of great significance to use molecular marker-assisted selection technology(MAS)in combination with conventional breeding to obtain high-yield,high-quality,and highly resistant corn varieties.This article outlined the commonly used molecular marker technology and the application of MAS in corn disease resistance and insect resistance breeding.At the same time,it clarified the limitations of MAS and looked forward to the future development prospects and advantages of MAS.
