| Abstract: | Molecular breeding is a new subject for livestock improvement, and it has played a role in provoting the studies on cattle meat quality traits and growth and development. This paper overviewed the latest research achievements of molecular marker and molecular breeding in beef cattle; and introduced the research progress made in beef cattle growth and production traits, including beef cattle candidate molecular markers, genome\|wide selection, micro\|satellite markers related with production performance, noncoding RNA as new markers for molecular breeding and adopting transgenic technology to improve important production traits of beef cattle. |
