Abstract
Despite some data on tall fescue diversity using molecular markers, mainly from United States accessions, there is a lack of knowledge on the global diversity all over the world for this species. The objectives of this study were to evaluate the sub-structure of tall fescue world wide variability and to place French cultivars into this sub-structure using AFLP markers. One plant per accession from 32 ecotypes and 40 plants from six French cultivars were used. A total of 116 polymorphic fragments were scored from two primers combinations. Clustering analysis on 32 ecotypes of tall fescue from all over the world showed two distinct clusters: European and Mediterranean types. In the Mediterranean type two clusters could be distinguished probably illustrating different colonization origins. The analysis of six French cultivars representing the French seed market showed six genetically distinct subsets which were included in the European type.
