Abstract: Maize (Zea mays) is the main crop in China, and drought is a primary abiotic stress during its growth, resulting in direct reduction in grain yield and quality, thereby posing a threat to food security within the global climate context. Therefore, it is imperative to identify drought-resistant germplasm resources, elucidate the molecular mechanisms of drought stress response, and breed drought-resistant varieties. Here, we review recent advances in the genetic dissection of drought resistance in maize using methods such as genome-wide association study, quantitative trait locus gene cloning and multi-omics analysis. Additionally, we introduce potential strategies for genetic improvement of drought resistance by leveraging the identified genetic resources while discussing future perspectives within this research area.
