Drought is increasingly frequent in the context of climate change and is considered a major constraint for crop yield. Water scarcity can impair growth, disturb plant water relations, and reduce water use efficiency. Pea (Pisum sativum) is a temperate grain legume rich in protein, fiber, micronutrients, and bioactive compounds that can benefit human health. In reducing pea yield due to drought, the intensity and duration of stress are critical. This review describes several drought resistance mechanisms in pea based on morphology, physiology, and biochemical changes during/after the water deficit period. Drought tolerance of pea can be managed by adopting strategies such as screening, breeding, and marker-assisted selection. Therefore, various biotechnological approaches have led to the development of drought-tolerant pea cultivars. Finally, the main objective of the current research is to point out some useful traits for drought tolerance in peas and also, mention the methods that can be useful for future studies and breeding programmes.
