Abstract:
The aims of this study is to use the phyllometric parameter to identify the autochthonous cultivars in north oust of morocco. Eighty six phyllometric parameters were measured/ calculated on 585 leaf samples from thirty nine grapevine cultivars, gathered during several years, from different traditional vineyard in Northwestern of Morocco. The leaves were scanned and images were analyzed using SuperAmpelo. Principal component analysis was performed to discriminate different accessions of cultivars. The results show a heterogeneous distribution of different accessions. This can be explained by the existence of the problem of synonymy and the homonyms frequently encountered in local varieties. In this study we tried to value these native cultivars by using the phyllometric approach. These varieties could be a valuable tool for improving local economies.
