        A new Gomchwi cultivar ‘Sammany’ was developed by a cross between Gomchwi (Ligularia fischeri (Ledeb.) Turcz.) and Handaeri-gomchwi (Ligularia fischeri var. spiciformis Nakai). Gomchwi is a common Korean name referring wild edible plant species within Ligularia genus. ‘Sammany’ has purple colored petiole ears and petiole trichome is absent. It has 2nd degree leaf vein density. Plant height, leaf length, leaf width and petiole length were 46.2, 19.1, 19.5 and 32.1 ㎝, respectively. Plant height was higher than ‘Gondalbi’. Bolting occurred in mid. July and it flowered from late August to early September. ‘Gondalbi’ bolted and flowered 26 days earlier than ‘Sammany’, and consequently has earlier flowering time more than 26 day. Leaf number of ‘Sammany’ was 156 per plant but ‘Gondalbi’ had 130. ‘Sammany’ had thicker leaves (0.61 ㎜) compared to ‘Gondalbi’ (0.46 ㎜). As a result, yield was higher in ‘Sammany (1,077 g/plant)’ than ‘Gondalbi (798 g/plant)’ and leaf hardness was lower in ‘Sammany (20.8 ㎏/㎠)’ compared to ‘Gondalbi (23.0 ㎏/㎠)’. In addition, ‘Sammany’ was found to be moderately resistant to powdery mildew. With enhanced agronomic and pathology traits, ‘Sammany’ was newly registered as a new Gomchwi cultivar (variety protection no. 131 on May 2017).

        Background : The research is designed to investigate the optimal cultivation technology and the growth of above-ground and below-ground sections as well as the photosynthetic characteristics for new ginseng variety “K-1” by differentiating the planting density under the conditions of transplanting and direct seedling. Methods and Results : The K-1 variety and hybrid variety (Jakyungjong) were selected for the research and the ginseng varieties were transplanted and directly sown in Yeoncheon area in 2013. The transplanting was made in the form of 5 lines × 9 rows (45 plants), 6 lines x 9 rows (54 plants), 7 lines × 9 rows (63 plants) and 8 lines × 9 rows (72 plants) in each lot (1.65㎡) while the direct seedling for testing was conducted three times in randomly blocked design in the form of 11 lines × 14 rows (154 plants), 12 lines × 14 rows (168 plants), 13 lines × 14 rows (182 plants). Various measures were collected from the 4-year transplanted ginseng and 3-year direct seedling ginseng in 2015 to find out the growth features and photosynthesis of above-ground section (rate of germination, leaf length, leaf width, stem length and leaf area index (LAI)) and the below-ground section (length, diameter, weight and class of roots). Conclusion : After the planting of the ginseng, the germination rate of K-1 for the transplanting was 85.1 ~ 92.0% across different plantation densities while that for the direct seedling was 67.7% ~ 77.9% across plantation densities, thus showing no significant difference between the two planting methods. LAI was higher for the higher planation density for both transplanting and direct seedling. As for the photosynthesis speed, the form of 6 lines × 9 rows showed the higher speed in transplanting while the form of 12 lines x 14 rows showed the higher speed in direct seedling. The photosynthesis of K-1 was higher than that of Jakyungjong. In the 4-year ginseng cultivated under the transplanting, diameter of roots, number of branch roots and weight of raw ginseng were the highest in the plantation density of 5 lines × 9 rows. The distribution of root weight was high with 23.3% and 20.0% for the 51~70g group and the 71g or above group, respectively, for the 4 year transplanted plants in the form of 5 lines × 9 rows. The growth for above-ground and below-ground sections for K-1 was better than that for Jakyungjong. As a result, it was found that the proper plantation density for the 4-year root in the transplanted K-1 was 5 lines × 9 rows considering the growth of the above-ground section, quantity and distribution of root weight.
