Four lupin species, , , , and , are grown as cool-season grain legume crops. Fifteen viruses infect them. Two of these, bean yellow mosaic virus (BYMV) and cucumber mosaic virus (CMV), cause diseases that threaten grain lupin production. Phytosanitary and cultural control measures are mainly used to manage them. However, breeding virus-resistant lupin cultivars provides an additional management approach. The need to develop this approach stimulated a search for virus resistance sources amongst cultivated lupin species and their wild relatives. This review focuses on the progress made in optimizing virus resistance screening procedures, identifying host resistances to BYMV, CMV, and additional viral pathogen alfalfa mosaic virus (AMV), and the inclusion of BYMV and CMV resistance within lupin breeding programs. The resistance types found in different combinations of virus and grain lupin species include localized hypersensitivity, systemic hypersensitivity, extreme resistance, and partial resistance to aphid or seed transmission. These resistances provide a key enabler towards fast tracking gains in grain lupin breeding. Where studied, their inheritance depended upon single dominant genes or was polygenic. Although transgenic virus resistance was incorporated into and successfully, it proved unstable. Priorities for future research are discussed.
四种羽扇豆物种，即[物种名称1]、[物种名称2]、[物种名称3]和[物种名称4]，作为冷季谷物豆类作物种植。有15种病毒感染它们。其中两种，即菜豆黄花叶病毒（BYMV）和黄瓜花叶病毒（CMV），会引发威胁羽扇豆谷物生产的病害。植物检疫和栽培控制措施主要用于管理这些病害。然而，培育抗病毒羽扇豆品种提供了另一种管理方法。开发这种方法的需求促使人们在栽培羽扇豆物种及其野生近缘种中寻找病毒抗性来源。本综述重点关注在优化病毒抗性筛选程序、鉴定对BYMV、CMV以及另外一种病毒病原体苜蓿花叶病毒（AMV）的宿主抗性，以及将BYMV和CMV抗性纳入羽扇豆育种计划方面所取得的进展。在病毒和羽扇豆谷物物种的不同组合中发现的抗性类型包括局部过敏反应、系统过敏反应、极端抗性以及对蚜虫或种子传播的部分抗性。这些抗性为快速实现羽扇豆谷物育种的进展提供了关键助力。在已研究的情况下，它们的遗传取决于单个显性基因或为多基因遗传。尽管转基因病毒抗性已成功导入[物种名称5]和[物种名称6]，但事实证明其不稳定。文中还讨论了未来研究的重点。
