Abstract:

Being effective only to the traits controlled by large-effect QTL,conventional marker-assisted selection(MAS)can hardly improve the quantitative traits that are controlled by many small-effect QTL.Later on, the genomic selection (GS) technology proposed in 2001 solves the problem of improving complex traits controlled by the minor polygenic effects due to its high prediction accuracy through estimating the breeding value of individual with high-density molecular markers. At present,it has been successfully applied to the genetic improvement of quantitative traits in animals and plants such as dairy cattle,pigs,sheep,maize,and wheat in the US,Canada,Australia,Germany,France and so on.As a breaking-through breeding technology and a hot spot in research and application now. In this review,we summarized the factors affecting predictive accuracy of GS and the research progress of GS in breeding maize,wheat,rice and rapeseed at home and abroad,and finally discussed the existing problems in its application. This review will provide some reference for GS of the crops in the future.
