The CO2 released from burning of fossil fuels is the prime cause of climate change, which have detrimental impact on agriculture and environment. Further, fossil fuels are non-renewable energy sources. This necessitates the pursuit of shift from fossil fuel to cellulosic biomass fuel for sustainable economic and environmental prosperity. The maize grain (starch) has been largely utilized for producing biofuel; however, it raised global debate for food versus fuel. The lignocellulosic portion (stover) of maize has remained unexplored for biofuel production due to its recalcitrant nature. Maize is a potential crop for cellulosic biofuel production due to its C4 photosynthetic activity, broad geographic adaptation, high carbon sequestration, and high nutrient use efficiency. Further, forage maize cultivars with high biomass and stover quality will revolutionize the industrial cellulosic biofuel production. Significant variation has been reported for biomass yield and stover quality traits for their improvement through breeding approaches. The tropical × temperate forage maize hybrids can be explored for high stover biomass and soluble sugars. The low lignin brown midrib mutants (bm) can be used for developing forage maize hybrids with high stover digestibility. Through utilizing advanced genomic tools, key genomic regions have been mapped for biomass, cell wall composition, and other bioenergy-associated traits in maize. Marker-assisted selection of these genomic regions can help in accelerated development of biofuel-specific forage maize cultivars. Further, genetic engineering approaches can be used for developing novel phenotypes with improved biomass and stover quality. In this chapter, the potential of forage maize and its improvement for better bioethanol conversion from lignocellulosic biomass are discussed.
