Abstract
A new Gomchwi cultivar 'Soomany' was derived from a cross between Gomchwi (Ligularia fischeri (Ledeb.) Turcz.) and Handaeri-gomchwi (Ligularia fischeri var. spiciformis Nakai). The investigation and selection of growth and yield characteristics were conducted from 2007 to 2015 in field and greenhouse of Highland Agriculture Research Institute, National Institute of Crop Science, Rural Development Administration, in Korea. On a newly developed cultivar 'Soomany', color of petiole ear is light green, petiole trichome is existent, trichome and light on the back of the leaves don't exist, and density of leaf vein is degree 4. Plant height, leaf length, leaf width and petiole length are 77.1, 22.3, 21.5 and 57.2 cm, respectively in the growth characteristics of the 2nd year. Plant size was also higher than that of 'Sammany' generally. Bolting date was on August 15. Flowering date was on September 19, about 9 days later than 'Sammany'. 'Soomany' and 'Sammany' had 149 and 133 leaves per plant, respectively. Total yield of 'Soomany' (1,623 g/plant) made a very good comparison with that of 'Sammany' (1,385 g/plant). 'Soomany' showed harder leaves (25.8 ㎏/㎠) than 'Sammany' (20.8 ㎏/㎠), whereas 'Soomany' had thinner leaves (0.53 mm) than 'Sammany' (0.62 mm). 'Soomany' variety has shown strong resistance to powdery mildew disease compared to 'Sammany'. In May 2019, the right of variety protection of 'Soomany' was registered as a new Gomchwi variety (Register No. 192).
