摘要

Sweet corn (Zea mays var. saccharata) has gained significant popularity in global agriculture due to its unique taste, improved nutritional profile, and consumer preference. Genetic advancements in sweet corn have played a crucial role in enhancing its palatability, nutritional quality and stress resilience. Key genetic improvements that have shaped modern sweet corn varieties elucidate the genetic basis of essential quality traits, including kernel sweetness, odour, pericarp thickness, and nutrient composition, which are influenced by key endosperm mutations. Additionally, the genetic regulation of stress resilience, encompassing both abiotic and biotic stresses is discussed, with an emphasis on genes and markers that facilitate breeding for sustainable productivity. Meanwhile, advancements in omics technologies, genomic selection (GS) and genome-wide association studies (GWAS) have provided a refined genetic roadmap for various essential attributes, their genes and regulatory mechanisms that contribute to consumer appeal. Advances in high-throughput phenotyping and genome-editing, are contributing to the rapid identification and development of cultivars with desirable attributes. By integrating conventional breeding with molecular tools for a targeted approach to quality traits, sweet corn improvement can be accelerated to meet the demands of the food system. This review synthesizes the current landscape of sweet corn genetics and highlights the importance of trait-based strategies and their relevance to quality-driven, climate-resilient, sustainable food production.
