Among legumes, faba bean (Vicia faba L.) is considered a very important crop because it has a high protein content that can be useful for human and animal consumption. Abiotic stresses affect all agricultural crops. However, like other crops, it is vulnerable to various environmental challenges. Drought stress affects faba bean crops' production and productivity, but plants can mitigate its effects through physiological and biochemical changes, requiring further study. To date, few faba bean cultivars have been identified as drought-tolerant; therefore, more research efforts should be made to identify more drought-tolerant genotypes to be utilized in breeding programs. Moreover, new trends and advances in faba bean genetic research should be ideally employed to improve drought tolerance in faba bean genetically and rapidly, along with physiological and breeding research. Unfortunately, research on the molecular breeding of the faba bean is very slow because of its genome complexity, and very few studies have reported quantitative trait loci (QTLs) associated with drought tolerance. This review highlights recent physiological, breeding, and genetic research studies conducted on drought tolerance in faba bean. Faba bean drought-tolerant genotypes, promising genes for expression studies under drought stress, and putative significant markers associated with drought tolerance identified through genetic association studies were reported in this review.Therefore, this review may be an essential source for faba bean breeders and geneticists to obtain the most up-to-date information on recent studies that have been conducted on drought tolerance in faba beans from physiological, breeding, and genetic perspectives and to continue research on drought stress in faba beans.
