The quality traits of horticultural crops, including the accumulation of nutrients and flavor substances, morphology, and texture, affect the palatability and nutritional value. For many years, efforts have been made to improve the quality of horticultural crops. The recent establishment of gene editing technology, with its potential applications in horticultural crops, provides a strategy for achieving this goal in a rapid and efficient manner. Here, we summarize research efforts aimed at improving horticultural crop quality through genome editing. We describe specific genome editing systems that have been used and traits that have been targeted in these efforts. Additionally, we discuss limiting factors and future perspectives of genome editing technology in improving horticultural crop qualities in both research and plant breeding. In summary, genome editing technology is emerging as a powerful tool for efficiently and rapidly improving horticultural crop quality, and we believe that the cautious application of genome editing in horticultural crops will generate new germplasms with improved quality in the near future.

园艺作物的质量特征，包括营养物质和风味物质的积累，形态和质地，都会影响适口性和营养价值。多年来，人们一直在努力改善园艺作物的质量。基因编辑技术的最新建立及其在园艺作物中的潜在应用，提供了一种以快速有效的方式实现这一目标的策略。在这里，我们总结了旨在通过基因组编辑改善园艺作物质量的研究工作。我们描述了已经使用的特定基因组编辑系统以及在这些工作中针对的特征。此外，我们讨论了在研究和植物育种中改善园艺作物品质的基因组编辑技术的局限性因素和未来前景。综上所述，
