From 41 cultivars of medicinal Paeonia lactiflora harvested in 1991, twelve cultivars, which gave higher root yield and more beautiful flowers, were selected, and these cultivars were cultivated for four years from 1992 to 1996. The root yield and the paeoniflorin and tannin contents in these cultivars harvested in 1996 were compared with those parent cultivars harvested in 1991. It becomes clear that the root yield was considerably affected by the weather and other cultivation conditions, whereas the amounts of chemical components were less affected. A significant correlation was observed between the paeoniflorin content and the tannin content in the root. It is possible to obtain a better cultivar by repeating the same procedure.
