The study explored the importance of maize germplasm resources in improving breeding efficiency, especially in the context of climate change and increasing environmental pressure. The study analyzed the diversity of maize germplasm resources and their conservation and collection status worldwide. The application of molecular technologies (such as SNP genotyping, whole genome association analysis, and NGS technology) in germplasm characterization was reviewed, and the key role of phenotypic evaluation in improving stress resistance and yield was clarified. It was proposed to promote the development of superior lines through pre-breeding and hybrid vigor utilization, and emphasized the importance of global cooperation in maize germplasm resource sharing and innovation. This study provides systematic strategic recommendations for the development of stress-resistant and high-yield maize varieties.
