Twenty six wild and cultivated accessions of collection of cardoon and globe artichoke were analyzed to evaluate genetic diversity using SRAP markers. Eleven qualitative and quantitative traits were evaluated and euclidean distances among genotypes were calculated. A total of fifteen primer pairs were initially assayed and 7 of them were finally selected due to their consistent amplification together with the clear banding patterns obtained. Genetic distances were calculated according to standardized Jaccard’s distance index (JDI). Both matrices were subjected to cluster analysis. Dendrograms showed that cardoons were clearly separated from artichoke. These results showed that SRAP markers will be an useful tool for studying genetic diversity in Cynara cardunculus.
