“…Latvia, which continues to develop new sweet cherry varieties focusing on spring frost tolerance [Ruisa 2008], has a limited area of production and its crop is destined primarily for domestic consumption. In Bulgaria, the sweet cherry production expanded in the 1980s [Kramer 1985] and reached 11,004 hectares in 1990, but has since declined to 6800 hectares in 2002 [Borovinova et al 2008]. Sweet cherry cultivars grown in Bulgaria include "Bing", which has been outperformed in consumer tests [Turner et al 2008], while "Hedelfinska" and "Van" had shares of 14% and 9%, respectively, in the total area planted.…”
