Utilization of energy crop is the major option for stable bioenergy production at low cost and that will not compete with food production. Further energy crop must be grown in marginal land. The objective of this study is establishing the scenario for bioenergy feedstock production using wild Miscanthus species in cold and snowfall area (CSA) where is not suitable for biomass production (BP) due to short and stressful growing season. Wild populations of Miscanthus sinensis derived from different areas were evaluated in CSA to identify major factors involved feedstock production. A scenario was established integrating environment (temperature, growing degree-days), M sinensis genotypes (morphological growth duration), field management (weed control, fertilization), harvesting time and comparison with other energy crops such as maize in CSA. Although the harvesting time of Miscanthus remains under consideration, it could be applicable that wild M sinensis population is domesticated as a promising energy crop in cold region with BP between 20〜30 t ha^<-1> without fertilizer input.
