摘　　要：Doubled haploid(DH)technology and synthetic apomixis approaches can considerably shorten breeding cycles and enhance breeding efficiency.Compared with traditional breeding methods,DH technology offers the advantage of rapidly generating inbred lines,while synthetic apomixis can effectively fix hybrid vigor.In this review,we focus on(i)recent advances in identifying and characterizing genes responsible for haploid induction(Hl),(ii)the molecular mechanisms of Hl,(ili)spontaneous haploid genome doubling,and(iv)crop synthetic apomixis.We also discuss the challenges and potential solutions for future crop breeding programs utilizing DH technology and synthetic apomixis.Finally,we provide our perspectives about how to integrate DH and synthetic apomixis for precision breeding and de novo domestication.
