On the basis of 22 morphological characteristics, seventy-two grapevine varieties intended for white wine production were arranged into three ecological-geographic groups, with two subgroups in each. The accuracy achieved was 80.56%. The starting basis for arranging varieties from the groups convarietas occidentalis Negr., subconvarietas iberica Nem., convarietas pontica Negr., subconvarietas georgica Negr. and convarietas orientalis Negr., subconvarietas anthasiastica Negr. was confirmed by discriminant analysis. The accuracy varied from 89.5% for the varieties convarietas occidentalis Negr., subconvarietas galica Nem., to 73.0% for convarietas pontica Negr. and subconvarietas balcanica Negr., and to 50% for convarietas orientalis Negr. and subconvarietas caspica Negr.
