Characteristics of early and late emergence groups in panax ginseng C.A. Meyer

The characters of aerial parts and root were investigated in early and late emergence groups of ginseng lines to obtain the basic information for ginseng breeding. Ginseng plants flowered about the middle of May regardless of early and late emergence. The aerial parts were more vigorous in the late emergence lines than in the early emergence lines. And the root characters of late emergence lines were also better than those of early emergence lines. Significant variation for several traits was observed in early and late emergence lines. Especially, significant correlation between root weight and some aerial part characters, such as stem length, stem diameter, and leaf area, was observed. Multi-stem ginseng plants were highly susceptible to the Alternaria stem rot as compaired with single stem ginseng plants. Therefore, the results above-mentioned suggests that it is desirable to select late emergence lines for high yield of ginseng roots.
