Box 436 Adama ARTICLE INFO ABSTRACT Article No.: 100719180 Type: Research DOI: 10.15580/GJAS.2019.4.100719180 Thirty (30) Sweet Sorghum genotypes were evaluated for 8 traits in a Randomized Complete Block Design (RCBD) with three replications at Melkassa Agricultural Research Center in 2018. The objective of the study were to develop best performed sweet sorghum genotypes that adapted to central rift valley area of Ethiopia and to identify best performed genotypes for agronomic traits, stalk yield and brix value. The analysis of variance showed that mean square of sweet sorghum genotypes was highly significant (p<0.01) for all traits studied. The analysis of variances of sweet sorghum genotypes evaluated for 8 traits revealed highly significant difference between the genotypes for most traits and significant difference among genotypes for days to heading. It was interesting to note that there were eight genotypes matured before the check while genotype MR#22XIS8613/2/3-1-3 was the late maturing with 133 days. Genotype Ent.#64DTN shown to head and mature early in both characters. In case of plant height, twelve genotypes were found to be taller than the check. Genotype IESV 91104 DL was taller than other all genotypes with the height 215cm. In sweet sorghum, tall and thick stems contribute more towards the millable cane yield and juice yield. There were twelve genotypes have brix values greater than 18% before grain filling while only ten genotypes scored greater than 18% at maturity stage. The genotype, IESV 92001 DL, was the superior genotype in brix values before grain filling and ICSB 654 also revealed highest in brix value at physiological maturity. The most important genotypes for showing excellent performance on grain yield per hectare obtained from IESV 92008DL, MR # 22XIS8613/2/3-1-3 and IS 2331with grain yield of 2791 kg/ha, 3416 kg/ha and 2677 kg/ha respectively, than the check variety (2530 kilogram per hectare).
