Sorghum (Sorghum bicolor (L.) Moench) grown for grain, forage, or fuel, has been considered as model biomass feedstock. Sweet sorghum belongs to the same species as grain sorghum, but is characterized by its rapid growth, sugar-rich stalk, and high biomass production, as well as its adaptation to adverse growing conditions. When used as feedstock, sweet sorghum (with higher brix value, high biomass) has the following advantages to produce bioethanol: a high biomass yield, and high carbohydrate content (e.g., fermentable sugars in the juice of the stem and structural sugars in the bagasse).

The ICRISAT Genebank conserve the largest collection of sorghum and it contains many high biomass accessions having higher Brix % (>14%). This subset provides list of high biomass accessions identified for their utilization sweet sorghum improvement program.
