Chinese foxglove(Rehmannia glutinosa) is receiving much attention as one of the principal medicinal crops and the crud drug. This study was conducted to obtain the basic breeding information of Chinese foxglove derived from tissue culture. To compare plant characteristics between local variety and tissue cultured seedlings, plant growth and root yield has been investigated. In addition, catalpol and free sugar contents were also analized. The ability for the storage of root stock originated from tissue culture seedlings were better than that of local variety. The growth and root yield of in vitro propagated plants were superior to those of conventionally propagated plants. Root yield of 1-year-old and 2-year-old seedlings investigated 112% and 246% respectively than Seacheon local shows 384 kg/10 a. Although there were no significant different between tissue culture seedlings and conventionally propagated one, slight decline of component contents in tissue culture plants were still existed. Investigated sugar content among Seocheon local, 1-year-old tissue culture seedlings, and 2-year-old tissue culture seedlings were 1.86%, 1.21%, and 1.10% respectively. Catalpol content as one of standard materials indicates 0.46% in Seocheon local and 0.40% in tissue cultured ones.
