摘要

This study is focused on the systematic inventory of the date palm cultivars found in the regions of Oued-Righ and Oued-Souf. Oued-Righ has 175 cultivars and Oued-Souf 56. The scope of the genetic diversity varies according to the types of plantations. Thus, traditional plantations present all of the cultivars inventoried. Conversely, modern plantations contain the following six cultivars: Deglet-Nour, Degla-Beida, Mech-Degla, Ghars, Tinicine, and Tantboucht. Finally, recently established plantations still maintain a varietal diversity even though it is less important. Generally speaking, nine cultivars were counted, namely Deglet-Nour, Degla-Beida, Mech-Degla, Ghars, Tinicine, Tantboucht, Tafzwin, Tanslit, and Hamraya. Nevertheless, only seven out of all the cultivars listed have a real economic importance, namely Deglet-Nour, Degla-Beida, Mech-Degla, Ghars, Tinicine, Tantboucht, and Tafzwin; the others are rare and yield dates of low marketable value. Finally, more than 50% of the cultivars inventoried are in danger of disappearing as they are old and produce no shoots..
