Use the qualitative parameters from grapes and grapes berries to identify the native vitis vinifera in Morocco

Abstract

 We have used qualitative parameters to characterize and identify the native cultivars vitis vinifera in Northwestern of Morocco. Thirty nine accessions of locale grapevine were selected for this study and for each tree fifteen grape and fifteen grape berries were describe using ampelographic descriptors OIV. The table of ampelographic modalities shows a variation within the parameters studied between the different tree and inside the tree of the same variety. This variation gives us a preliminary idea of the diversity of the tree from local accessions of grapevine how deserves to be preserved and protected. Our results showed a significant variation of the shape of berries not only between the varieties but also inside the same variety.
