영문 초록

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 referringwild 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 toearly September. ‘Gondalbi’ bolted and flowered 26 days earlier than ‘Sammany’, and consequently has earlier floweringtime more than 26 day. Leaf number of ‘Sammany’ was 156 per plant but ‘Gondalbi’ had 130. ‘Sammany’ had thickerleaves (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 ㎏/㎠)’. Inaddition, ‘Sammany’ was found to be moderately resistant to powdery mildew. With enhanced agronomic and pathologytraits, ‘Sammany’ was newly registered as a new Gomchwi cultivar (variety protection no. 131 on May 2017).
