Common bean (Phaseolus vulgaris L.) is an important leguminous crop from the nutritional point of view, as it is rich in micronutrients as well as protein content. Drought stress is a major abiotic stress which reduces yield of crops to a major extent. Common bean is mostly cultivated under rain-fed conditions and due to very frequent droughts at the critical growth stages, there is a reduction in its average yield to a larger extent. Therefore, there is an urgent need of developing drought resistant common bean cultivars. Advances in omics approaches have opened a path to tackle many unresolved problems pertaining to crop sustainability. In this review we have discussed various options of using genomics-based approaches, mainly molecular marker assisted approaches (MMAA) to address drought tolerance in common bean. Moreover, we have also emphasized the limitations of conventional breeding approaches in tackling complex traits in crop plants.
