Background : The roots of Codonopsis pilosula (Franch.) Nannf are used as medicines such as expectorants, and they are edible. Codonopsis pilosula (Franch.) Nannf currently has a very small cultivation area, and there are no breeding cultivars, most of the native species are cultivated in the farm house. Therefore, it is important that identification of collecting species characteristic in order to breeding strategy. In this study, morphological features of the leaves and stems of the collecting species in the area were observed.
Methods and Results : The morphological characteristics of mansam collected from three areas including Cheolwon (41 accession), Jeongseon (19 accession), and Pyeongchang (15 accession) were investigated at the flowering stage on leaf and stem. As a result of investigation of leaf characteristics, The leaf shape was the most frequent with 78.9% in the kidney type, 8.5% in the cardiac type, 7.0% in the wide-elliptical type, and 2.8% in the egg and egg-oval type. The leaf length was the most frequent with 67.1% in case of short, 28.6% in case of middle, and 4.3% in case of long. The leaf width was 67.1% in case of middle, 30.0% in case of broad, and 2.9% in case of narrow. Leaf hair was 47.1% in case of plenty, 27.1% in case of middle, and 25.7% in case of small number. The degree of greenness of the leaves was 60.0% in case of middle, 31.4% in case of darkness, and 8.6% in case of lightness. The degree of pigmentation of anthocyanin in petiole was 41.4% in case of lightness, 31.4% in case of darkness, and 27.1% in case of middle. As a result of investigating the characteristics of stem, The presence and absence of hair on the stem was 95.7% in case of little, 2.9% in the middle, and 1.4% in case of plenty. The degree of staining of anthocyanin in the stem was 42.9% in case of middle, 30.0% in case of darkness, and 27.1% in case of lightness.
Conclusion : We intend to use this data as a basic data for cultivating varieties by supplementing investigation of traits such as expansion of collection area and investigation object and flower shape in the future.
