Onion (Allium cepa L.) is the main bulbous crop cultivated commercially globally. It is the main condiment crop and consumed second in number after tomato. Contrarily, abiotic stresses are impacting the growth, yield, and quality of the onion. Single stress is significantly resulting in poor yield, whereas combined abiotic stresses are resulting in devastating yield losses under natural conditions. Additionally, it is predicted the water scarcity is increasing on yearly basis and it also triggers other abiotic stresses. Therefore, it is the major threat to onion production, and it is predicted to cause devastating yield losses. Modern genetic approaches have broadened our horizon to develop stress resilient vegetables to cope with future climatic changes to ensure food security. Several studies have reported the influence of single and combined abiotic stresses on major vegetable crops. However, limited literature is available to understand the response of onion to single and combined abiotic stresses. It is the dire need of the hour to study the response of onion to abiotic stresses. This opinion report enlightens the importance of modern genetic approaches for development of stress tolerant onion cultivars.
