【Abstract】 Seed protein content is one of the main objectives of soybean quality improvement. In this paper, theauthors summarized the development of soybean genetic map construction and genome sequencing, andclarified the progress of QTL mapping of soybean seed protein content from linkage analysis based on thesegregating population and association analysis based on the natural population. Furthermore, the authorsdiscussed the existing problem of marker-assisted selection(MAS) breeding for seed protein content insoybean. Finally, the future research trend of molecular genetic improvement of seed protein content insoybean was discussed. It is expected that this paper will provide a reference for the selection of new soybeanvarieties with high protein content.更多还原
