Discrimination the accessions of grapevine cultivars Taferyalt with phyllometric parameters

The northwestern region of Morocco is rich in native vine cultivars where the problem of synonymy and homonymy is very common and causes the spread of varieties or the color of the fruits. The name of the grape cultivar Taferyalt has become inseparable from the name of the northwestern region where the cultivar is met under different names. In front of this situation, we tried to classify the accessions which have the same ampelographic character but with the different names (synonyms) or which showed several names which are given to the same variety (homonyms). The results of the phyllometric analyzes confirmed that these accessions are different.
