The integration of genomic technologies into crop improvement has revolutionized agricultural science, addressing the challenges posed by climate change, population growth and food security. By enabling the identification and manipulation of genes associated with critical traits such as drought tolerance, disease resistance and nutritional enhancement, genomics has accelerated breeding programs and enhanced precision in trait development. Techniques such as genome sequencing, marker-assisted selection, genomic selection and CRISPR-based genome editing have facilitated the development of high-yielding, stress-resilient crops. Notable successes include the creation of Golden Rice, enriched with provitamin A and drought-tolerant maize, designed to thrive in water-scarce regions. Moreover, genomics has advanced systems-level approaches like genome-wide association studies (GWAS), offering insights into complex trait networks. Integrative strategies, including multi-omics data analysis, bridge the gap between genotype and phenotype, providing a comprehensive understanding of plant systems. Emerging trends, such as AI-powered genomics, epigenetic editing and synthetic biology, hold promise for further optimizing crop improvement. These advancements underscore the role of genomics as a cornerstone of sustainable agriculture, ensuring resilient food systems for a growing global population. However, challenges such as high costs, data complexity and ethical considerations persist, necessitating interdisciplinary collaboration and innovation. This review explores the principles, applications and future trends of genomic crop improvement, highlighting its transformative potential in meeting the evolving demands of agriculture.
