XVI International Botanical Congess

RAPD analysis was used to study the phylogenetic relationships between species in Allium section Schoenoprasum and for the investigation of the intraspecific differentiation of A. schoenoprasum. RAPD analysis clearly distinguishes all species of section Schoenoprasum. The arrangement of the accessions of A. schoenoprasum in all dendrograms mirrors the geographical distribution. Informally described morphological types of A. schoenoprasum could not be confirmed by RAPD analysis, but represent ecological adaptations. European accessions are genetically closely related and appear as sistergroup to an Asian clade. The analysis also supports a relatively recent migration of A. schoenoprasum to the New World.
