Abstract: Pre-harvest sprouting(PHS) of wheat is a worldwide climate disaster, which has severe effects on grain yield and quality. The genetics of PHS resistance of wheat is complex and many factors are involved. A lot of quantitative trait loci(QTLs) that associated with PHS have been mapped, but only a few major genes have been identified and deeply studied,such as R(red grain color gene),Vp-1(viviparous-1),MFT(MOTHER OF FT AND TFL1) and Sdr(seed dormancy resistance gene).Progress on mapping of QTLs, molecular mechanism of genes above and breeding for PHS resistance were reviewed.Furthermore,deficiencies existing in current researches and the future direction of improving PHS resistance were discussed.
