The obtained results showed that there was a great diversity between the studied cultivars and a significant compatibility between the male and female date trees for each studied cultivar. However the leaf properties results showed compatibility between the studied female date trees cultivars and the male date trees in the following characteristics: paper length - maximum width of paper - number of thorns - length of the area free from thorns. The results of the study on the reproductive organs showed the compatibility of each cultivar between the male and female date trees in the following characteristics: the number of pollen - the length of the pollen - the width of the pollen - the number of the Shamrock - the length of the Shamrock - the number of flowers per Shamrock, the results of the hierarchical clustering (classification Ascendant Hierarchique (CAH)) demonstrated that there are common characteristics between each cultivar and its male and female date trees. These results describe the validity to applicate the concept of the cultivar on the male date trees.Arأشجار النخيلPhoenix dacfylifera LMaster
