Due to its frequent hybridisation and introgressions in the Iberian Peninsula, the genus Quercus, comprises several taxonomic problems. After revising the morphology of different species in central (Quercus broteroi, Q. faginea and Q. pyrenaica) and southern Iberian Peninsula (Q. broteroi, Q. canariensis, Q. lusitanica, Q. pyrenaica and Q. broteroi × Q. canariensis), molecular biology techniques are used to find out their possible relationships. This work presents a preliminary study of the variability in several groups of Quercus using RFLPs.
