Diversity of the Local Varieties from grapevine Tree in the Northwestern of Morocco

Abstract

The culture of grapevine in Morocco is ancestral and preserves a particular importance in the traditional agroecosystems of the Riffian mountains. But the importance of varietal diversity remains ignored. These study was carried out to evaluate this diversity, for that a investigations and investigations were carried out in north-west of the country. The stations were selected according to the importance of the orchards of grapevine tree in the agroecosystem. A complete description morphological, physiological and pomological relating the tree and the fruit was carried out. The culture of grapevine in the area of study show a great diversity with 21 listed native varieties. One notes a great confusion of denomination on the level of the prospected varieties. This problem can be with several causes and mainly with the errors of appreciation of the characters or the differences of local names which vary from one locality to another.
