A High Yielding and Salt Resistance Ginseng Variety ‘Cheonryang’

Recently ginseng farmers are demanding ginseng varieties having resistance to disasters to cope with climate change. Thus, it is essential to develop new varieties which have resistance to heat and physiological disorders to stably produce ginseng. ‘Cheonryang’ is a new ginseng variety developed from a Yeoju line of high yielding and salt resistance. This variety was selected in the farmer’s field by the ginseng breeding team of Department of Herbal Crop Research, NIHHS, RDA. It shows red leaf senescence at maturing, red berry and convex leaflet shape in cross section. The time of emergence, flowering and berry maturity of the ‘Cheonryang’ is 2, 3, 5 days faster than those of ‘Chunpoong’. Stem length of ‘Cheonryang’ is 2.3 cm shorter than that of ‘Chunpoong’, as 41.3 cm but stem diameter is l.0 cm thicker than that of ‘Chunpoong’, as 6.4 cm. It shows similar total weight to total root and main root length compared to ‘Chunpoong’ and main root diameter is thicker 5.3 mm than that of ‘Chunpoong’. Number of seeds of ‘Cheonryang’ is fewer than that of ‘Chunpoong’ but 1,000-grain weight and stratification rate are higher than those of ‘Chunpoong’. The yield performance of this variety was 536 kg/10a in local adaptability test for two years, is 12% higher than that of ‘Chunpoong’. It is resistant to damping-off, anthracnose, phytophthora blight, root rot, mulberry mealybug and nematode, mediate resistant for alternaria blight. Yellow spot of aerial part and red skin rarely observed of root, ‘Cheonryang’ shows moderate resistance at high temperatures.
