Research Progress on Genetic Linkage Map Construction and QTL Mapping of Flowers
In recent years,with the fast development of molecular biology,molecular marker technique especially,the breeding work of flowers changed from traditional crossbreeding to molecular breeding.The marker-assisted breeding containing genetic linkage map construction,quantitative trait loci mapping,and so on had become one of the hotspots in molecular plant breeding.At present,the construction of genetic linkage map always focused on crops and forests.The development of flower genetic linkage map was on the initial stage.Construction of high density genetic linkage map and precise QTL position will facilitate accelerating the progress of flower breeding research.This study summarized research progresses on the construction of genetic linkage map of flower,including the chosen of parents and segregation population,the main molecular markers methods and the located QTL.The existing problems were discussed in this research field and gave some proposals for its direction of development and emphasis of research prospects in the future.
