Abstract: Although tetraploid alfalfa is one of the most practically important forage legumes, its genetic mapping and the QTL identification of its significant traits are lagging behind other diploid crops due to its complex genetic background. High-density genetic and physical mapping of diploid alfalfa was initiated several years ago and these studies have laid the theoretical foundation for the genetic mapping and QTL identification of tetraploid alfalfa. This new work on tetraploid alfalfa will be greatly accelerated by the rapid development of third generation molecular markers and sequencing technology. On this basis it will be possible to increase the efficiency of alfalfa breeding programs, especially by using marker-assisted selection. This paper reviews the genetic map construction and QTL analysis of alfalfa. It outlines research progress and the prospects of association mapping and genomic selection in the future.
