Pistacia genus includes some ten species originating from four different phytogeographic regions, the Mediterranean being the most important area of their natural distribution. Pistacia vera is the only species cultivated for food. All wild Pistacia species, besides used as a source of fuel, resin, etc., play an important role in the cultivation of pistachio trees by providing rootstocks resistant to pests, diseases and environmental stresses. Pistacia species are facing serious problems of genetic erosion. Threats to their diversity come from the destruction of natural habitats and the use of few selected genotypes in modern pistachio cultivations. Existing variability found in Mediterranean countries should be properly surveyed, safeguarded and characterized. Efforts in this direction are needed and on-going initiatives at international level for the promotion of the conservation and use of these valuable species should be encouraged. Data on some pomological characteristics of the Mediterranean pistachio germplasm are provided
