In recent times, sugarcane has been the focus of several programs aiming at the production of fuel ethanol. Compared to starch-based sources such as corn, production of ethanol from sugarcane has obvious advantages due to the amount of photosynthate accumulated during the crop cycle and the low production costs of sugarcane. The rise of cellulosic ethanol technologies will allow the conversion of part of the sugarcane lignocellulosic materials into ethanol, thus maximizing the utilization of this crop as a biofuel feedstock. Despite the rapid progress made in recent years, breeding and biotechnology have been hampered by the complex nature of sugarcane genetics and physiology. Biotechnology and marker-assisted breeding have great potential for generating cultivars and optimizing the utilization of sugarcane sucrose and lignocellulosic materials as a source of fuel ethanol. Other sugar-producing plants, such as sweet sorghum and sugar beet, are also potential biofuel sources, especially in water-limited and temperate areas, respectively, where sugarcane cultivation is not economically viable.
