Introduction of American cranberry in Lithuania started in 1963. Since this time the largest collection of American cranberry has been collected at the Kaunas Botanical Garden of Vytautas Magnus University. Long-time investigation and evaluation of the introduced cranberry cultivars showed that the cultivar ‘Ben Lear’ and hybrids BL (BL-6, BL-8, BL-10) are the most favourable for cultivation in Lithuania. The cultivars ‘Bergman’ and ‘Stevens’ were selected as very promising for cultivation in plantations as well. The cultivar ‘Pilgrim’ and the clone Bain 10 were distinguished for their good yield but their berries ripen late and could be damaged by early autumn frosts in some yearsBotanikos sodasVytauto Didžiojo universiteta
