Abstract：Gene editing is an emerging technology modifying biological traits by knocking out，replacing and inserting target genes．As an accurate and efficient genetic engineering method，gene editing technology has overcome the restriction of interspecific reproductive isolation on traditional breeding，influence of adverse gene linkage，and technical bottleneck of long breeding fixed number of years，etc．Therefore，it has huge application potential．This paper reviewed the development history of gene editing technology；summarized the research progress of gene editing technology in gene function and trait improvement of vegetable crops，including Solanaceae，Cruciferae，Cucurbitaceae，etc.；and discussed the difficulties and countermeasures in applying gene editing technology for different vegetable crops，so as to provide references for wide application of gene editing technology in vegetables．
