In order to obtain the fundamental data for the selection of favorable lines of Atractylodes ovata, individual variations of the external morphological characteristics, growths, and the amounts of chemical substances were examined. Different growths, i.e., dry weights of roots, rhizomes, shoots, leaves, heads, and numbers of leaves and heads were observed between the one and two year old plants cultivated in the field and those cultivated in the pot soil. The amounts of dilute ethanol- soluble extracts from those rhizomes were about the same, though the coefficient, of variation of essential oil contents and the amounts of sesquiterpene compounds and other components of two year old dry rhizomes were larger than the corresponding values of one year old dry rhizomes. And the essential oil contents of one and two year old dry rhizomes were not correlative with the dry weight of their rhizome. And also, the essential oil contents of two year old rhizomes per year from 1991 to 1994 and each cultivated localities i.e., Tokyo, Ibaraki and Kumamoto, ranged from 0.3 ml/ 50.0 g to 1.6 ml/50.0 g. The rhizomes of F1 generations from narrow leaf type × narrow leaf type, broad leaf type × broad leaf type, and white head type × white head type, indicated TLC pattern and acetylenic compound of the standard plant of A. ovata. Thus it seemed that it was possible to select the favorable lines of A. ovata from those characteristics.
