摘　　要：草种是草坪业的基础,但我国缺乏自己培育的草坪草品种,所用草坪草种主要依赖于进口,因此草坪草育种工作亟待加强。常规育种周期长、效率低且难以实现精准靶向育种,而现代生物技术为草坪草育种提供了新的有效途径,其中构建草坪草高效再生体系,加快繁殖速度,对拥有再生体系的草坪草种进行遗传转化是其关键。本文主要综述了近年来对部分冷季型和暖季型草坪草的再生体系研究,总结了影响再生过程的关键因素、存在问题等,同时对未来草坪草再生领域的发展进行了展望,以期对今后草坪草新品种的研发、推广和应用提供参考。Grass seeds are the foundation of lawn industry,but we lack our own turfgrass varieties and the turfgrass seeds used in practice mainly rely on importation from abroad.Therefore,turfgrass breeding needs to be strengthened urgently.The conventional breeding cost a long period of time,low efficiency and is difficult to achieve precise targeted breeding.However,modern biotechnologies provide a new and effective way for turfgrass breeding,in which the key is a construction of an efficient regeneration system for turfgrass to accelerate the propagation speed,and be carried out its genetic transformation with regeneration system.This review mainly summarized the researches on the regeneration systems of some cold season and warm season turfgrasses in recent years,and focused on the key factors and existing problems affecting the regeneration process,and prospected the future development of turfgrass regeneration,with a view to provide a reference for the research,development,promotion,and application of new turfgrass varieties in the coming days.
