Application of ampelographic parameters to differentiate native Vitis vinifera L. cultivars

This study was conducted in three vegetation successive periods (2015, 2016) to determine ampelographic characteristics of the 39 grapevine accessions prospected in the Northwestern of Morocco by ampelographic criteria using OIV descriptors. The data were processed by multivariate statistical procedures. The integration of the obtained data with ampelographic data would be very important for the accurate identification of the Moroccan cultivars and can become a significant tool for the certification of quality grapevine produced in specific region.
