Vegetables are an important component of the agriculture production systems and an important part of a healthy diet. Traditional breeding methods are difficult to meet the growing demands for yield and quality of vegetable crops; therefore, new approaches are required. CRISPR/Cas9 gene-editing technology has the advantages of short time period, simple and quick operation, and high editing efficiency. It has become an important tool for plant science and molecular breeding and has been widely used in the creation and genetic improvement of vegetable germplasm resources. This article mainly reviews the application progress and challenges of CRISPR/Cas9 in vegetable improvement, to provide a new perspective for vegetable breeding.

蔬菜是农业生产系统的重要组成部分，也是健康饮食的重要组成部分。传统育种方式难以满足蔬菜作物产量和品质日益增长的需求；因此，需要新的方法。CRISPR/Cas9基因编辑技术具有周期短、操作简单快捷、编辑效率高等优点。它已成为植物科学和分子育种的重要工具，被广泛应用于蔬菜种质资源的创造和遗传改良。本文主要综述了CRISPR/Cas9在蔬菜改良中的应用进展和挑战，为蔬菜育种提供新的视角。
