Abstract

With increasing challenges such as climate change, pest pressure and the need to improve nutrient content, traditional breeding methods face limitations. Genetic engineering offers promising solutions through precise gene-editing technologies such as CRISPR-Cas9 and transgenic technologies, enabling the development of corn varieties with higher yields, resistance to biological and abiotic stresses, and enhanced nutritional status. This study aims to explore the transformative potential of genetic engineering in future maize breeding, and the findings show that significant progress has been made in creating drought-tolerant, pest-resistant and nutrient-rich maize through genetic modification, and that genetic engineering, combined with traditional breeding and molecular tools, will play a key role in meeting future food security needs and promoting sustainable agriculture.
