The various crop species are major agricultural products and play an indispensable role in sustaining human life. Over a long period, breeders strove to increase crop yield and improve quality through traditional breeding strategies. Today, many breeders have achieved remarkable results using modern molecular technologies. Recently, a new gene-editing system, named the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 technology, has also succeeded in improving crop quality. It has become the most popular tool for crop improvement due to its versatility. It has accelerated crop breeding progress by virtue of its precision in specific gene editing. This review summarizes the current application of CRISPR/Cas9 technology in crop quality improvement. It includes the modulation in appearance, palatability, nutritional components and other preferred traits of various crops. In addition, the challenge in its future application is also discussed.
各种作物是主要的农产品，在维持人类生命方面发挥着不可或缺的作用。长期以来，培育者一直努力通过传统的育种策略来提高作物的产量和改善质量。如今，许多培育者利用现代分子技术取得了显著的成果。最近，一种新的基因编辑系统，名为成簇规律间隔短回文重复（CRISPR）/Cas9 技术，也成功地改善了作物的品质。由于其多功能性，它已成为作物改良最受欢迎的工具。它通过在特定基因编辑中的精确性加速了作物的育种进程。本文综述了 CRISPR/Cas9 技术在作物品质改良中的应用。它包括对各种作物外观、口感、营养成分和其他受欢迎特性的调节。此外，还讨论了其未来应用的挑战。
