During the past 40 years in Bulgaria a change has been observed in the cultivar composition and reduction of the total vineyards from 200,000 ha in 1980 to 63,647 ha in 2020. Climate change and the introduction of more disease-resistant grape cultivars have led to the threat of extinction of traditional old local cultivars such as ‘Ribi mekhur’, ‘Lisicha opashka’, ‘Orlovi nokti’, ‘Chaush’, ‘Keratsuda’, etc., through which the country has built market positions in a number of countries. In the present study, some old local cultivars threatened with extinction have been mapped and recommendations for their restoration in Bulgaria have been given.
