Abstract: Doubled haploid breeding can achieve rapid homogenization of genetic material through the combination of haploid induction and doubling technology, which significantly accelerates the speed of pure line production and the selection process in hybrid breeding, is a common key technology in agricultural breeding. In this paper, we briefly review the methods and progress of plant haploid induction and chromosome doubling, introduce the latest gene editing-mediated in vivo haploid induction technology, and discuss and prospect the application of haploid breeding technology in Medicago sativa and other legumes forage.

Key words: haploid breeding technology, genome editing technology, legume forage, alfalfa
