Sweet sorghum may differ from grain sorghums by only a few genes, that control plant height, the presence of juice in stem, and the presence of sugar in the juice. It is also widely used for the production of forage and silage for animal feed.
Efforts have been made to produce crystalline sugar from sweet sorghum juice in early 1970s in Iran. The possibilities of
growing sugar beet, potato, sweet sorghum and vines for the production of ethanol for use as a fuel in Italy are reviewed [6]. The recent oil crises and Gulf war renewed the commercial production of sweet sorghum for use as fuel and fuel additives. There are several advantages to use sweet sorghum instead of sugarcane, as the biomass source for alcohol production [7].
