Biotic and abiotic stresses are known to affect onion production, causing significant yield losses, similar to other vegetables and main crops. It is estimated that about 40% of overall losses in agricultural production is related to insects, pests, and weeds. Likewise, environmental fluctuation and climate change are threatening the production rate of onion. Strangely, in the era of omics approach to understand plants’ responses to environmental changes, there is limited literature regarding onion response to biotic and abiotic stresses. This chapter enlightens the impacts of biotic and abiotic stresses with the potential exploitation of modern plant improvement techniques. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.eninfo:eu-repo/semantics/closedAccessBiochemicalBreeding toolsClimate changesMorpho-physiologyOnionStressesBook Chapter14316210.1007/978-981-19-5367-5_72-s2.0-85161255771N/A
