In the past decade, genomics-assisted breeding (GAB) has emerged as a pivotal approach for leveraging modern genomic resources and enhancing allelic variation for germplasm improvement and varietal development. As global population growth intensifies the demand for agricultural output, there is an urgent need to enhance food security and feed availability. Future breeding tools will focus on developing climate-resilient genotypes to address global food security challenges. Recent advancements in GAB have enabled the creation of well-annotated crop pan-genomes, providing a comprehensive overview of genetic diversity and revitalizing gene catalogs for various species. The proposed GAB 2.0 aims to accelerate the manipulation of allelic variation, facilitating the rapid introduction of novel traits into crop improvement programs. This approach prioritizes the optimization of crop genomes by harnessing beneficial alleles and eliminating detrimental ones, ultimately leading to the development of climate-smart cultivars with enhanced nutritional value. Furthermore, the application of CRISPR/Cas systems in crop research has shown success in enhancing resistance to abiotic and biotic stresses. Coupled with high-throughput phenotyping and advanced data analytics tools like AI and machine learning, agriculture is advancing towards greater mechanization and digitalization, setting the stage for a sustainable future in crop production.
