Breeding experiments were carried out in order to clarify whether or not genetic differences might exist between Datura stramonium L. and D. tatula L. concerning morphological characters and alkaloid content in leaf. The results of experiments showed that the two species are genetically similar in morphological characters except in a few quantitative traits such as plant height and number of leaves per plant. Chemical analyses clarified that no differences are present between the two species either in the alkaloid content on dry weight basis or in the kinds of alkaloids present in leaves. However, a wide variation in alkaloid content was observed among individual plants in the F_2 progeny of the interspecific hybrid, and this seems to suggest that the parental species may not necessarily be identical in all the genetic factors that influence alkaloid production. Our results support the proposal by Blakeslee and others that D. stramonium and D. tatula should be considered as two varieties of a single species.
