These studies were conducted to provide basic information on Korean ginseng cultivars and breeding lines (Panax ginseng C. A. Mey.) and to identify the variations that can be utilized in ginseng breeding programs. The agronomic characteristics was used to clarify the genetic relationships among Korean ginseng cultivars and breeding lines and to classify them into distinct genetic groups. Angle of petiole and number of fibrous root showed a wide variation from 15.0~67.8˚ and 0~5, respectively. The average plant length was 54.2cm with a range of 37.9~64.8cm and the average stem diameter was 5.6mm with a range of 4.0~7.5mm. The average stem length was 31.9cm with a range of 21.8~37.9cm and the average root weight was 38.1 g with a range of 23.0~52.0 g. The 24 Korean ginseng cultivars and breeding lines were classified into 4 groups based on agronomic characteristics using the complete linkage cluster analysis. The I, II, III and IV groups included the 60.8%, 7.4%, 13.1% and 8.7% of the cultivars and breeding lines, respectively. The breeding lines in group I could be characterized as the group with the highest growth characters and yield components, such as plant length, stem diameter and root weight. The root weight, the yield component, had highly significant positive correlations with stem diameter, plant length and stem length.
