The study sought to conduct evaluation trial of six sweet sorghum lines under Pangasinan [Philippines] condition. Specifically, it aims to determine their agronomic characteristics and incidence of pests and diseases and recommend lines that are suitable for stalk, grain and bio-ethanol production. There were significant differences observed for plant height, plant appearance score, lodging score, days to 50% flowering, stalk diameter, stalk juice volume, seed size, Brix values, stalk yield, stripped Stalk yield, stalk diameter, stillage yield, stalk juice yield, panicle weight, grain weight and yield. The mean agronomic characteristics of the lines evaluated showed that, in terms of plant height, stalk yield, stripped stalk yield, stalk juice yield, stalk juice volume, and stalk diameter, the ICSV 700 and ICSV 93046 lines have produced the greatest yields. On seed and grains characteristics, the NTJ 2 and SPV 422 lines have produced the greatest yields. In terms of grain weight, the ICSV 700 and ICSV 93046 lines have the heaviest grains. The ICSV 93046 and ICSV 700 lines have the least resistance to lodging, lower plant stand, and longest days to attain 50% flowering. ICSV 93046 and ICSV 700 are good planting materials for stalk and stalk by-products purposes. The NTJ 2, SPV 422, and IS 2331 lines produce greater grains. NTJ 2 and SPV 422 are the most resistant to sweet sorghum pests and diseases.
