A major obstacle to sustainable food production in the field of modern agriculture is the growing threats posed by biotic and abiotic stresses. Innovative breeding techniques are needed to address these issues and create resilient crop genotypes to withstand these stresses. The management of biotic stress is dependent on genetic resistance that is derived from conventional breeding techniques, marker-assisted selection, and genomic methodologies including genome-wide association studies (GWAS). Using methods like classical breeding, mutation breeding, and transgenic, important genes and traits linked to stress tolerance can be identified. The development and use of stress-tolerant varieties are promoted by the identification and introgressions of stress-related genes and quantitative trait loci (QTLs) into elite germplasm, which is made easier by multidisciplinary and participatory breeding approaches. But to fully realize the potential of breeding interventions to mitigate biotic and abiotic stresses and safeguard global food security through agricultural sustainability in changing environmental conditions and evolving pest pressures, breeders, researchers, policymakers, and farmers must work with coordination to resolve obstacles like limited genetic diversity and regulatory constraints.
