Cucumber mosaic virus (CMV) is a prevalent virus affecting the quality and yield of pepper, resulting in yield losses of greater than 80% during severe local epidemics. Cultural practices and the heavy use of agrochemicals are the most common control measures for CMV. Sources of resistance provide a practical reference and a basis for breeding for CMV resistance. Genetic factors underlying CMV resistance have been studied and advanced breeding lines and cultivars with improved resistance have been developed by traditional breeding methods. Additionally, QTLs or genes for CMV resistance have been identified and can be utilized for marker-assisted resistance breeding. This review focuses on status and prospect of CMV against different virus strains, host resistance, and its applied genetics. With the advent of novel technologies, more useful markers and precise approaches can facilitate the progress for improving CMV resistance in .
黄瓜花叶病毒（CMV）是一种普遍存在的病毒，会影响辣椒的品质和产量，在严重的局部流行期间会导致产量损失超过80%。栽培措施和大量使用农用化学品是控制CMV最常见的措施。抗性来源为CMV抗性育种提供了实用参考和基础。已经对CMV抗性的遗传因素进行了研究，并通过传统育种方法培育出了抗性有所提高的先进育种系和品种。此外，已经鉴定出CMV抗性的QTL或基因，可用于标记辅助抗性育种。本综述重点关注CMV针对不同病毒株系的现状与前景、寄主抗性及其应用遗传学。随着新技术的出现，更多有用的标记和精确方法可以促进提高辣椒CMV抗性的进展。
