Genomics of Forage Crops

Forage crops, including ryegrass, alfalfa, and clover, are crucial for sustainable agriculture and livestock production. However, climate change threatens yield and nutritional quality, necessitating the integration of traditional and advanced breeding techniques. Genomics has revolutionized forage crop improvement by enabling precise identification and manipulation of genetic traits. Advances such as GWAS, QTL mapping, HTS, and CRISPR/Cas9 gene editing improve yield, quality, and stress resilience. Functional genomics, proteomics, and metabolomics are essential for understanding gene functions and metabolic pathways in forage crops. These strategies help develop forage varieties with enhanced biomass, digestibility, and stress adaptation, while also identifying resistance genes and stress–response pathways for breeding resilient cultivars. Genomic discoveries in forage improvement face challenges due to genetic complexity and limited resources, necessitating international collaboration and public–private partnerships to accelerate progress. The book chapter discusses the importance of integrating artificial intelligence (AI) and big data analytics in breeding programs, focusing on developing multi-trait forages for climate change and global livestock needs, and bridging traditional breeding with genomic technologies. Future research should integrate AI and big data analytics into breeding programs for improved efficiency and precision, focusing on developing multi-trait forages for climate adaptation and sustainable livestock production.
