Abstract

The alkaloid profiles of ripe capsules of Papaver bracteatum, P. orientate and their interspecific hybrids (F₁ and BCF₁) were determined and compared. In the hybrids the thebaine content declined, while that of oripavine was higher than in the parental species. The results provided genetic evidence for the biosynthetic linkage between those alkaloids. A genetic model, assuming dosage effect interaction between the genomes of the two species was elaborated. The significance of the results for breeding purposes was considered.
