Due to their ability to provide a thorough knowledge of the metabolomics, proteomic, transcriptomic, and genomic profiles of these crops, omics techniques have completely changed the area of bioenergy plant research. Worldwide projects to develop fodder crops have as their main goals the production, quality, and potential for bioenergy of biomass. In contrast to cereals or other main food crops, the general rise in fodder quality improvement is not as high. A more thorough knowledge of the bioenergy forage crops may be achieved by the effective use of omics approaches, including metabolomics, proteomics, transcriptomics, and phenomics. This chapter gives a summary of the several omics approaches that are applied in the development of bioenergy forage crops. Key genes, processes, and biomarkers that lead to increased biomass output and quality can be found by researchers using genomics, transcriptomics, proteomics, and metabolomics. The creation of sustainable bioenergy sources might be completely transformed by the merging of omics data with cutting-edge breeding methods. The influence of current developments in omics technology on the field of bioenergy forage crop research is highlighted in this chapter. There is a lot of room for enhancing the digestibility, edible quality, and nutrient content of forage to increase the quality of fodder. The existing omics technologies for the six main fodder crops, sugarcane, sorghum, maize, cowpea, oats, and alfalfa, are briefly described in this chapter.
