摘　　要：穗发芽是影响小麦品质和产量的重要自然灾害之一。了解小麦穗发芽抗性遗传和分子基础,有助于穗发芽抗性改良。本文从穗发芽抗性QTL发掘、功能标记开发、穗发芽主要抗源以及抗穗发芽分子育种几方面对小麦穗发芽研究进展进行综述,并对今后小麦穗发芽抗性研究重点及育种思路进行讨论,以期为小麦穗发芽遗传研究和抗性育种提供参考。Pre-harvest sprouting(PHS),one of the important natural disasters in wheat production,causes serious quality deterioration and significant yield loss.Understanding of the genetic and molecular basis of PHS is beneficial to improve PHS resistance in breeding program.We summarized some progress made in the resistant QTLs and genes associated with PHS,development of functional markers,resistant germplasms and molecular breeding for PHS.We also discussed on the emphasis in PHS resistance research and proposed breeding methods for PHS resistance improvement.This review will provide important information for genetic study and resistance improvement of PHS in breeding program.
