Abstract: One-hundred and twenty-four amplified fragment length polymorphism (AFLP) and 49 random amplified polymorphic DNA (RAPD) markers have been used to distinguish between 20 and 23 commercial chicory cultivars, respectively. These were all Cichorium intybus var. foliosum F-1 hybrids, currently used in hydroponic forcing. Five-hundred and twenty RAPD primers (OPERON) were tested, of which 156 resulted in reproducible patterns and 26 yielded polymorphisms. Two-hundred and fifty-six AFLP primer-combinations were tested and six combinations were selected for identification purposes. Similarity indices were measured and clustering has been done using pairwise comparison. Both types of marker provide similar conclusions. Two major clusters are formed, representing late and early cultivars. All cultivars were identified using 10 informative RAPD primers or three AFLP primer combinations. A low degree of polymorphism was detected between some early cultivars, suggesting a narrow genetic base in their breeding strategy.
