Biomass potential of novel interspecific and intergeneric hybrids of Saccharum grown in sub-tropical climates

Abstract Sugarcane-derived biomass is a promising source of renewable energy to meet the growing demands for biofuel. Currently, modern sugarcane cultivars are unable to provide enough biomass due to their narrow genetic base and susceptibility to abiotic and biotic stresses. We have evaluated total...
