Quantitative Trait Locus Mapping of Seed Protein Content in Soybean: Progress

Seed protein content is one of the main objectives of soybean quality improvement. In this paper, the authors summarized the development of soybean genetic map construction and genome sequencing, and clarified the progress of QTL mapping of soybean seed protein content from linkage analysis based on the segregating population and association analysis based on the natural population. Furthermore, the authors discussed the existing problem of marker- assisted selection (MAS) breeding for seed protein content in soybean. Finally, the future research trend of molecular genetic improvement of seed protein content in soybean was discussed. It is expected that this paper will provide a reference for the selection of new soybean varieties with high protein content.
