摘　　要：百合是一种集药用、食用和观赏为一体的单子叶植物。百合遗传多样性丰富,市场新品种大多是通过杂交选育而成。百合具有基因组大、杂合度高、品种倍性复杂等特点,常常出现杂交育种障碍,致使百合育种进展缓慢。单倍体育种技术已成为常规杂交育种的重要补充,大大提高了现代植物育种效率。本文综述了百合单倍体诱导策略以及单倍体的保持与加倍,尤其介绍了基于基因组编辑技术的单倍体诱导新技术,为百合采用现代分子育种研究策略与综合开发利用提供重要参考资料。Lily is a monocotyledonous plant which is used for medicinal, edible and ornamental purposes. Lily is also genetic diversity with large genome, high heterozygosity and complex ploidy. Most of the new lily varieties in the flower market are the products of hybridization breeding. Haploid breeding has become an important supplement to conventional crossbreeding and is a fast and effective method among modern plant breeding technologies. In this review, we summarized the induction strategy, doubling, and maintaining of haploids. Furthermore, haploid inducer-mediated genome editing(IMGE) techniques were summarized. This review will provide a reference for modern molecular breeding research and use of lily.
