‘Sunmyoung’: A Variety with High Production Stability Due to Its Resistance Against High Temperature and Lodging Stresses

‘Sunmyoung’ is a high-yielding variety that is resistant to damage from lodging and high temperatures. Out of the 30 lines collectedfrom a farmhouse in Yeoju in 2001, individual plants of ‘Sunmyoung’ were selected from a testing plot with artificial high-temperature stressand were further bred using the pure line separation breeding method. Preliminary and advanced yield trials were conducted in Suwon andYeoju from 2005-2013, and regional adaptability trials were conducted in Yeoju and Anseong from 2014-2016. The rates of high-temperaturestress for two- and three-year old ‘Sunmyoung’ were lower than those of the ‘Sunil’ variety by 46.2% and 34.1%, respectively. The lengthof the stem and small leaflets of Sunmyoung were 6.2 cm and 5.1 cm shorter than those of Sunil, and the width of the leaflets was shorterthan that of Sunil by 3.9 cm-indicating a higher resistance of ‘Sunmyoung’ against lodging damage. In the regional adaptability test, theyield of Sunmyoung was 523 kg/10a, which was 5% higher than that of ‘Sunil’ (498 kg/10a). The content of ginsenoside in ‘Sunmyoung’was 19.2 mg/g, which was lower than that of ‘Sunil’ (22.38 mg/g). Since ‘Sunmyoung’ is more resistant to high temperature stress (than‘Sunil’), lodging stress, Rhizoctonia solani, and Alternaria panax leaf spot, and has a decent production stability with higher yields, it isexpected to contribute towards the quality improvement of raw materials in ginseng production (Registration No. 7495).
