Two Erianthus varieties jointly developed by JIRCAS and the National Agriculture and Food Research Organization (NARO), namely, JES1 (No. 27533) and JEC1 (No. 27534), and which are suitable for production of biomass fuels have been registered. JIRCAS aims to reduce greenhouse gas emissions by expanding the production and utilization of high biomass productivity crops as biofuels. Erianthus is a perennial grass that can be cultivated at low cost and with high biomass yield. The two Erianthus varieties registered this time are capable of biomass production of about 30 tons/ha in Kyushu and 15 tons/ha in the northern Kanto region providing stable resources for biomass energy projects using abandoned farmlands from Kyushu to northern Kanto. So far, Erianthus variety JES1 has been successfully cultivated on abandoned farmlands in Sakura City, Tochigi Prefecture and used for production of pellet fuel（http://www.naro.affrc.go.jp/publicity_report/press/laboratory/nilgs/077296.html）and the registration of this variety is expected to further expand it's cultivation in the future.
