In this paper,the progress in QTL mapping for polygenic resistance in crop plants was described,including construction of mapping population (F?1,F?2,DH,RIL,BIL and NIL),measurement of resistant phenotypes,marker-assisted selection and so on.

• 从作图群体(F1、F2、DH、RIL、BIL和NIL)构建、抗性表型测定和标记辅助育种等方面论述了多基因抗性QTL作图的最新研究进展。
