Abstract：
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 Capsicum.
摘要：
黄瓜花叶病毒(CMV)是影响辣椒品质和产量的流行病毒,在严重的局部流行病期间导致产量损失超过80%。文化习俗和大量使用农用化学品是CMV最常见的控制措施。抗性来源为CMV抗性育种提供了实际参考和依据。已经研究了CMV抗性的遗传因素，并通过传统育种方法开发了具有改良抗性的高级育种系和品种。此外,已经鉴定了CMV抗性的QTL或基因，可用于标记辅助的抗性育种。本文综述了CMV对不同病毒株的研究现状和前景,宿主抗性，及其应用遗传学。随着新技术的出现，更有用的标记和精确的方法可以促进提高辣椒CMV抗性的进展。
