국문 초록

Aralia elata (Miq.) Seem. is a deciduous broad-leaved shrub distributed throughout northeast Asia, including Korea. The new shoots that sprout in early spring in Korea are consumed as a high-quality wild vegetable. As the trees are easy to cultivate and can be harvested from the second year after planting, they have become a popular forest product for short-term income. Conventional cultivars had large and numerous thorns on their stems and shoots, making pruning or collecting shoots difficult. However, some thornless cultivars exhibited poor cold resistance, which limited their cultivation areas. To solve this problem, excellent trees were selected across the country and tested to develop a novel cultivar with no or few thorns, strong cold resistance, and early harvesting times. Based on these results, the cultivar, ‘Yeongchun’, was bred. Although no significant difference in the size of ‘Yeongchun’ shoots was observed when compared to that of the control, its weight per piece was 34.6 g, which was 74% larger than the 19.9 g measured for the control. Moreover, the number and diameter of shoots originating from primordia in the roots of Yeongchun were 6.1 and 55.7 mm, respectively, which were about twice as large as the 2.6 and 29.7 mm measured for the control, resulting in a higher yield. In addition, the harvesting period was more than a week earlier than that of general individuals, showing the characteristics of early production (Grant number 323).
