Doubled haploid (DH) technology and synthetic apomixis approaches can greatly shorten breeding cycles and thereby enhance breeding efficiency. Compared with traditional breeding methods, DH technology offers the advantage of being able to rapidly generate 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 (HI), (ii) the molecular mechanisms of HI, (iii) spontaneous 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 offer a perspective on integrating DH and synthetic apomixis within precision breeding and de novo domestication.
