In Syria there are approximately 10 million pistachio trees planted over 60 000 hectares. The number of pistachio bearing trees is 4 million, these trees produced about 30 000 tons of nuts in 1997. According to this estimate Syria is classified as the fifth largest pistachio producing country in the world after Iran, USA, Turkey and China. The distribution of pistachio production is concentrated in the north and central Syria, mainly in the regions of Aleppo (45%), Idleb (35%) and Hama (20%). In Syria there are about 20 female pistachio varieties. This paper reports detailed information on three main varieties namely Ashoury (Red Aleppo), Red Oleimy and White Batoury. In addition data on production trials of the nut for eight varieties are also being provided. The other nine varieties are little known and need further study to characterize them in collaboration between the University of Aleppo and IPGRI.
