Abstract
A new Gomchwi cultivar ‘Gommany’ was bred by crossing between Gomchwi (Ligularia fischeri (Ledeb.) Turcz.) and Handaeri-gomchwi (Ligularia fischeri var. spiciformis Nakai). The selection and investigation of growth and yield characteristics were conducted from 2006 to 2011 in field and greenhouse of Highland Agriculture Research Institute, NICS, Rural Development Administration. The color of petiole ear was purple. Petiole trichome existed, but light of leaf back did not. Density of leaf vein was 5 degree in a newly developed cultivar ‘Gommany’. Plant height, leaf length, leaf width and petiole length were 47.7, 16.3, 21.2, and 31.4 ㎝, respectively in the 3 year of growth characteristics. Plant size was also higher than that of ‘Gondalbi’. Bolting and flowering time were Aug. 5 and Sept. 10, respectively. In contrast, Bolting time of ‘Gondalbi’ showed 25 days quite earlier bolting time compared to ‘Gommany’, Which led to earlier flowering time. ‘Gommany’ showed higher number of leaves (138) per plant compared to ‘Gondalbi’ (130). Furthermore, yield was 97% higher in ‘Gommany’ (1,575 g/plant) than in ‘Gondalbi’ (798 g/plant). ‘Gommany’ showed higher leaf thickness (0.69㎜) than ‘Gonalbi’ (0.46 ㎜), and consequently showed more hardness in leaf characteristics (24.3 ㎏/㎠) compared to ‘Gondalbi’ (23.0㎏/㎠). ‘Gommany’ showed higher resistance in the susceptibility of powdery mildew compared to ‘Gondalbi’. ‘Gommany’ cultivar was registered as a novel variety with number 90 in The Minister of the Korea Forest Service on December 2015.
