Miscanthus giganteus is a tall (up to 3 m) perennial sterile grass originating from Japan (Hodkinson et al., 2002). It can be harvested yearly with a sugar cane

harvester and can be grown under cool climates like that of northern Europe and USA. Like other bioenergy crops, stems may be burned for heat and electric power production or fermented to ethanol. It combines many of the desirable properties of a biofuel crop. As a perennial C4 plant, it produces consistently high biomass yields (8-15 tons/ha dry weight) over many years with little or no nitrogen application, shows good energy balance and low mineral content, which improves fuel quality. However, the yield potential might not be fully used when this variety is cultivated under varying climatic conditions. Interspecific crosses between sorghum and Miscanthus could complement Miscanthus in adaptation to stress conditions in arid climates. Similarly, Miscane, a hybrid between sugar cane and Miscanthus, could potentially combine the high productivity of both species with the perenniality and adaptation of Miscanthus to colder climates (Jakob et al, 2009).
