| dc.description.abstract | Due to the increasing price and depletion of fossil fuels there a necessity to find an alternative source of fuel. Sweet sorghum (Sorghum bicolor (L.) Moench) which is similar to grain sorghum with sugar-rich stalks and a water-use efficient crop has a very good potential as an alternative feed stock for ethanol. Production cost of cultivation of sweet sorghum is 3 times lower than sugarcane. Similar to sugarcane, sweet sorghum juice extracted from stalks is high in sugars that are readily fermentable. In the present study fifteen sweet sorghum genotypes were screened for higher ethanol production. Genomic DNA was isolated using CTAB (2 %) method from young leaves. These genotypes were analysed for genetic diversity using SSR markers. SSR markers have particular importance because of their abundant distribution, highly polymorphic, reliable, and co-dominance nature. Matured plants juice was extracted from the stalk of the plants, RSSV 138 and URJA genotypes showed highest total sugar concentration of 14.78 % and 14.39 % respectively. The juice was fermented using Saccharomyces cerevisiae among which RSSV 138 and CSH 22SS genotypes showed highest ethanol yield of 13.25 g/l and 13.01 g/l respectively. From this study the sweet sorghum genotypes having high sugar concentration were identified and can be used for bioethanol production. | en_US |
