Abstract
Variation of major characteristics of 140 sweet sorghum germplasm which had been collected from domestic and foreign countries were investigated to study the possibility of bioethanol production in reclamed soil of Korea. Averages of culm length, ear length, the number of nodes, stem diameter, fresh weight yield, and growth duration from seeding to heading were 175 cm, 26 cm, 9, 11.6 mm, 12.1 t/ha, and 96 days, respectively. Sugar content, which has a great effect on bioethanol, ranged from 5.7 to 23.5 Brix (average 14.1 Brix). Sugar contents of selected two varieties were more than 20 Brix. Fresh weight yield ranged from 20 to 50 t/ha (average 12.1 t/ha). Fresh weight yield of selected three varieties were more than 30 t/ha. Culm length showed highly significant positive correlation with the ear length, the number of nodes, stem diameter, fresh weight yield, and growth duration from seeding to heading. The number of node showed highly significant positive correlation with stem diameter and fresh weight yield. Fresh weight yield showed highly significant positive correlation with culm length, the number of nodes, stem diameter, and growth duration from seeding to heading.
