The phylogenetic relationship between different Cichorium intybus cultivars and cultivar groups was studied. A total of 127 random amplified polymorphic DNA markers have been used to distinguish between 51 Cichorium intybus cultivars belonging to three different cultivar groups. A principal component analysis was performed on the complete data set and a clear grouping of chicory cultivar groups was observed. The three chicory groups tested (root chicory, witloof and pain de sucre) were separated from one another in the principal component plots. The first two axes accounted for 43.9% of the total variation. Although the chicory used in traditional forcing in soil and the red chicory cultivars were related more to each other and to the chicory cultivars from the witloof group, they still formed separate groups in the principal component plot.
