Sorghum ([Sorghum bicolor (L.) Moench]) is the fifth largest cereal crop globally used as food, feed, fodder, fuel, and fiber. Biofuels are gaining importance owing to increasing uncertainties in supply of fossil fuels and the environmental pollution associated with their use. Because of its high biomass production potential and wider adaptability, sorghum is among preferred crops for lingo-cellulosic or second generation (2G) biofuel production. A potential approach to improve sorghum as a biofuel feedstock is to reduce the cell wall lignin content leading to high cell wall digestibility and increasing cellulose and hemicellulose contents. Presently, production of 2G biofuels needs genotypes with good plant height, high biomass yield, high cellulose and hemicellulose and low lignin content.
