The post-genomic era is considered a renaissance phase of crop breeding with technological leaps by integrating genomic tools and techniques into conventional breeding approaches at a whole new level. This paradigm shift leverages genome-wide association studies (GWAS), CRISPR-based genome editing, and high-throughput sequencing to magnify our understanding of crop genetics and facilitate the development of improved varieties. The emergence of multi-omics approaches such as transcriptomics, proteomics, and metabolomics has further enhanced our potential to dissect complex traits and alter breeding strategies. The crop breeders are now qualified to address global crises like climate change, resource scarcity, and food security with the advent of these innovations with unmatched precision. This section deals with the advancements in genomic technologies, including machine learning and artificial intelligence, and their application in crop improvement that convey breeding efficiency, trait discovery, and development of resilient crops. The importance of ethical considerations in placing these technologies is emphasized for the continued integration of the latest genomic insights and field performance data.
