초록
Background: Stable production of Korean ginseng (Panax ginseng C. A. Meyer) is highly dependent on specific climatic conditions. Recently, ginseng yield and quality have been negatively affected by climate changes, particularly by global warming. Therefore, developing new varieties with enhanced tolerance to high-temperature stress is essential for coping with elevated temperatures. Methods and Results: To increase the production stability and enhance the yields of Korean ginseng, a high-temperature stress tolerant elite line with a high yield was collected from a farm field in Pocheon, and a new variety, ‘Jinwon,’ was developed using a pure-line selection method. ‘Jinwon,’ which has a green leaf and red berry, exhibits red leaves at senescence and a convex leaflet shape in cross section. ‘Jinwon’ sprouted two days earlier than ‘Chunpoong,’ and its flowered and fruit-ripening period occurred three days earlier. ‘Jinwon’ has approximately 28% higher 4-year-old root yields (576 ㎏/10a) than that of ‘Chunpoong’ (519 ㎏/10a). The ginsenoside content in ‘Jinwon’ was 25.9 ㎎/g, which was higher than that of ‘Chunpoong’ (10.9 ㎎/g). Conclusions: ‘Jinwon’ exhibited strong resistance to high temperatures and Alternaria blight, with higher yields and better functional properties than ‘Chunpoong’. As a result, ‘Jinwon’ was registered as a variety (grant number 7461) with the Korea Seed and Varieties Service in 2019.
