Background: The qualitative characteristics of aerial parts, such as stem diameter or number of ginseng leaves, are highly correlated with the root yield. correlation between the qualitative characteristics of aerial parts and root yield are limited.
Methods and Results: The materials used in this study were cultivated after collecting 219 germplasms from nine regions in Korea, and the growth characteristics of the aerial and underground parts were investigated. The qualitative charateristics of eight 8 aerial parts such as stem color, leaf shape, and shape in cross-section of a leaflet, were investigated and their correlation with root yield was analyzed. The characteristics that showed a significant positive correlation with root yield were the shape in the cross-section of the leaflet (r = 0.71, p < 0.01), degree of additional leaflets (r = 0.37, p < 0.05), and color of leaf at senescence (r = 0.60, p < 0.01). Contrastingly, leaf shape had a negative correlation (r = -0.42, p < 0.01). Among the qualitative characteristics of aerial parts high-yield germplasms weighing more than 55 g per individual, 13 lines (65%) had a convex shape on the cross-section of the leaf. Germplasms that exhibited red color in leaf at senescence generally showed a high root yield.
Conclusions: High-yield varieties can be developed early through the correlation between root yield and qualitative characteristics of the aerial parts, this could also help farmers in harvesting high quality seeds.
