2. Materials and methods

Multi-year research included work on autochthonous and domesticated grapevine varieties in Montenegro. A detailed review of available literature and writing of earlier and contemporary authors regarding autochthonous and domesticated grapevine varieties was done. For a better understanding, we did also ampelographic and genetic analysis of selected varieties. Analysis included 188 samples of old representative vines aged between 50 and 300 years that are grown in affirmed vineyards in Montenegro. These studies also included 17 biotypes of the Kratošija variety (Figure 2) that were collected in 1987 in an experimental field in Ljeskopolje-Podgorica.
