Climate change is threatening environmental and nutritional security. In this scenario, forage crops and their wild relatives may contribute to maintain ecosystem services and minimize the effects of global warming. We reviewed the literature regarding the ecological, agronomic and nutraceutical values of wild Onobrychis Miller species (sainfoins, Family Fabaceae). We also discuss their application prospect and existing problems hampering their widespread domestication. Wild species of the genus Onobrychis have certain interesting agronomic and ecological features such as perenniality, deep root system and high stress tolerance, which make them suitable for future cultivation under climate change. Wild Onobrychis species are multipurpose species which can be utilized for fodder and honey production under harsh environmental conditions. In addition, wild Onobrychis species exhibit anti‐oxidant, anti‐diabetic, anti‐inflammatory, anti‐tumor, anti‐microbial, anti‐stressor and many other pharmacological effects. Wild Onobrychis species have not been the subject of detailed studies. Compared with the cultivated forage legumes, wild Onobrychis species are still under‐exploited despite their potential to alleviate forage and food insecurity, either by domestication or by providing novel alleles for breeding purposes of the cultivated species Onobrychis viciifolia. Our review aims to increase scientific awareness towards exploring the potential uses of wild Onobrychis species to tackle current climate change.This article is protected by copyright.
