Description Some 100 sweet-stalk sorghum genotypes (G) were evaluated for stalk sugar percentage (Brix), grain and biomass yields and other agronomic traits during 1967 at Anantpur (shallow soil and low rainfall), Parbhani (adequate rainfall) and Patancheru (postrainy season; irrigated). Significant effects of G, environment (E) and G X E interactions were observed for all the characters studied. Most genotypes belonged to the medium maturity group (108 to 150 days). Genotypes IS6962, IS7555, IS9901, IS18162, IS18164, IS19674 and IS21005 gave high grain (1.34-2.49 t/ha) and biomass yields (13 to 20.6 t/ha) across environments; these lines may be suitable for breeding dual-purpose sorghums. IS131, IS11496, IS15102, IS19674 and IS11152 showed consistently high stalk sugar (17-21%) and biomass (13-21 t/ha) in all three environments; they could be used as parents for breeding sweet-stalk sorghums. IS776, IS18162 and IS18164 showed appreciable grain yield and high percentage of stalk sugar and the last two accumulated high biomass; these lines may be useful as parents for breeding multipurpose sorghums. IS3940 was early, and showed least differences (+- 2.9) in time to flowering across all environments, and showed high stalk sugar (15.5%) levels except at Anantpur., 11 ref., Some 100 sweet-stalk sorghum genotypes (G) were evaluated for stalk sugar percentage (Brix), grain and biomass yields and other agronomic traits during 1967 at Anantpur (shallow soil and low rainfall), Parbhani (adequate rainfall) and Patancheru (postrainy season; irrigated).
