This study was conducted to select the superior lines through the investigation of morphological or agronomic characteristics of Sorghum bicolor collected from the South Korea and United States. The selection of superior baselines was made by comparing the plant height, stem diameter, tiller number, ear type, ear length, ear width, leaf length, leaf width and leaf vein color. On average, five accession lines (09-SB-010, 09-SB-020, 09-SB-025, 09-SB-027, 09-SB-056) among of collections for South Korea were showed more than 250 cm in plant height. Two accession lines (09-SB-006, 09-SB 048) exhibited above 4 cm stem diameter. In terms of tiller number, 56.6 % of collected accessions revealed possessed three tillers. In this result, about 14.5 % of collected accessions showed leaf length of above 90 cm and leaf width more than 10 cm. The colors of all leaves were white. The semi-compact elliptical ear type constituted to 32.3% among the 62 accessions collected in South Korea. The mean ear length value of the collected accessions appeared to be 29.2 cm. The sample collected from United States (09-SB 104) was selected as an excellent line by checking the plant height (419 ± 10.1 cm). This report displayed that crop characteristics of S. bicolor have a significant morphological and agronomic differences which could be useful for plant breeding program and genetic resources.
