Wheat dwarf disease (WDD) is an important disease of monocotyledonous species, including economically important cereals. The causative pathogen, wheat dwarf virus (WDV), is persistently transmitted mainly by the leafhopper and can lead to high yield losses. Due to climate change, the periods of vector activity increased, and the vectors have spread to new habitats, leading to an increased importance of WDV in large parts of Europe. In the light of integrated pest management, cultivation practices and the use of resistant/tolerant host plants are currently the only effective methods to control WDV. However, knowledge of the pathosystem and epidemiology of WDD is limited, and the few known sources of genetic tolerance indicate that further research is needed. Considering the economic importance of WDD and its likely increasing relevance in the coming decades, this study provides a comprehensive compilation of knowledge on the most important aspects with information on the causal virus, its vector, symptoms, host range, and control strategies. In addition, the current status of genetic and breeding efforts to control and manage this disease in wheat will be discussed, as this is crucial to effectively manage the disease under changing environmental conditions and minimize impending yield losses.
小麦矮缩病（WDD）是单子叶植物的一种重要病害，包括具有经济重要性的谷类作物。致病病原体小麦矮缩病毒（WDV）主要由叶蝉持久性传播，可导致严重的产量损失。由于气候变化，传毒介体的活动期延长，且这些介体已扩散到新的栖息地，导致WDV在欧洲大部分地区的重要性增加。根据综合虫害管理，栽培措施以及使用抗性/耐性寄主植物目前是控制WDV的唯一有效方法。然而，关于小麦矮缩病的病理系统和流行病学的知识有限，已知的少数遗传耐性来源表明还需要进一步研究。考虑到小麦矮缩病的经济重要性及其在未来几十年可能增加的相关性，本研究全面汇编了关于最重要方面的知识，包括致病病毒、其传毒介体、症状、寄主范围和控制策略等信息。此外，还将讨论目前在小麦中控制和管理这种病害的遗传和育种工作现状，因为这对于在不断变化的环境条件下有效管理该病害并尽量减少即将到来的产量损失至关重要。
