摘　　要：从韭菜大小孢子母细胞的减数分裂、胚囊和花粉的发育过程、胚胎发育和种子的形成、无融合生殖性状的遗传等方面对韭菜无融合生殖种子的形成机制进行综述,同时对韭菜无融合生殖特性的研究方向和在韭菜育种中的应用前景进行了展望,以期为今后韭菜无融合生殖机制的阐明和韭菜遗传育种研究提供参考。In this paper,the formation mechanism of apomictic seed in Chinese chive was reviewed from the meiosis of megaspore mother cell and microspore mother cell,the development of embryo sac and pollen grain,the embryonic development and seed formation,and the heredity of apomixis.In the mean time,the research direction of apomictic characteristics and its application prospect in Chinese chive breeding were prospected,with a view to provide reference for the clarification of apomixis mechanism and the study of genetics and breeding of Chinese chive in the future.
