Abstract
Sweet sorghum [Sorghum bicolor (L.) Moench] contain high sugar-rich stalks like sugarcane. A total of 200 sweet sorghum germplasm accessions were used in the crossing programme to develop high brix and high biomass sweet sorghum varieties. Thirty-nine F9s with high brix and high biomass were evaluated for 11 agro-morphological and seven biochemical traits during kharif seasons of 2008–2010. Analysis of variance showed significant differences among genotypes for all traits studied. Large variations was found for traits viz., field brix (4–22 %), stem fresh weight/5 plants) (1,667–6,250 g) and stem dry weigh/5 plants (833–5,000 g), juice brix (12.4–24 %), juice volume/5 plants (142–1,667 ml), total soluble sugars (9.35–20.82 %), reduced sugars (0.11–3.74 %) and juice purity (49.33–80.72 %). It is important to identify superior genotypes for ethanol production in terms of per cent juice brix, juice volume, total soluble sugars, and high biomass.
