摘要：
The genetic diversity analysis of 15 barley landraces was carried out using RAPD markers. These landraces were collected from various bioclimatic Tunisian zones. The amplification products varied from 4 to 11 bands ranging between 250 pb and 3000 pb. On 698 fragments counted, 578 are polymorphic showing a high level of polymorphism (82.8%). The relationship between the studied landraces was evaluated according to (UPGMA) method that classified barley landraces in 4 homogeneous groups. Among which, the group D included the majority of the landraces with the introduced variety 'Martin'. The genetic distance between these landraces is reduced, may be because of the presence of a common ancestor which led to a narrow genetic diversity.
