The green peach aphid, here abbreviated as green peach aphid (GPA), is a significant global pest of pepper. Conventional insecticide use risks the development of resistance and harms beneficial insects, whereas the deployment of resistant pepper cultivars offers an effective, economical and eco‐friendly management strategy. However, no GPA resistance gene has yet been identified in pepper. In this study, greenhouse and field screening for resistance to GPA in 24 pepper cultivars identified 'ZDC' as highly resistant and 'DYJJ' as highly susceptible. Subsequent inheritance analysis using these cultivars as parents showed that the segregation ratio of resistant and susceptible offspring was 1:1 for F₁ plants and 3:1 for F₂ plants. This indicated that pepper resistance to GPA was controlled by a single dominant gene. The highly resistant cultivar 'ZDC' may enable incorporation of resistance in future breeding programmes following further investigations to establish a fuller understanding of the genetics of GPA resistance in this species.

辣椒（Capsicum spp。）品种对绿桃蚜（Myzus persicae）有抗性

绿色桃蚜，在这里缩写为绿色桃蚜（GPA），是辣椒的重要全球害虫。传统的杀虫剂使用可能会产生抗药性并危害有益昆虫，而部署抗药性辣椒品种可提供有效，经济和环保的管理策略。然而，在辣椒中尚未鉴定出GPA抗性基因。在这项研究中，温室和田间对24个辣椒品种对GPA的抗性筛选确定“ ZDC”为高抗性，“ DYJJ”为高易感性。使用这些品种作为父母后续遗传分析表明，抗性和易感后代的偏析比为1：1与F _1种植物和3：1与F ₂植物。这表明胡椒对GPA的抗性由单个显性基因控制。在进一步研究以建立对该物种GPA抗性遗传学的更全面了解之后，高抗性品种“ ZDC”可能使抗性纳入未来的育种计划中。
