摘要

Barnyard millet, a highly nutritious and climate-resilient minor millet, holds great promise for food and nutritional security in an era of increasing environmental challenges. This review explores its journey from wild weedy ancestors to cultivated forms, highlighting the importance of global germplasm collections as valuable genetic resources. The plant and floral morphology are discussed as understanding the plant’s morphology is crucial for breeders aiming to develop improved varieties. While molecular markers have facilitated genetic diversity studies, the complexity of the barnyard millet genome presents significant challenges. However, advancements in next-generation sequencing, comparative genomics, and multiomics are transforming research on this underutilized crop. Comparative genomics allows the transfer of genomic insights from well-studied millets such as foxtail and finger millet, whose genomic resources are valuable for barnyard millet improvement. However, genomic divergence among these species can limit the direct application of QTLs or gene functions. Integrating species-specific genomic data with functional validation through gene expression studies and genome editing can enable effective utilization of these resources in barnyard millet breeding. Although the application of multiomics in barnyard millet is still evolving, it has already yielded groundbreaking insights, paving the way for breeding varieties with enhanced stress resilience and superior nutritional quality. This review underscores the urgent need to accelerate research in this direction, ensuring that barnyard millet reaches its full potential in sustainable agriculture and global food systems, particularly in the face of climate change.
