investigated European cranberry accessions comprised from 18.8 to 53.3 % of the total phenoliccompounds.As several authors have reported cranberries and these specific biochemical components are beingassociated with human health attributes, such as maintenance of urinary tract health and antioxidantstatus (Povilaityt÷ et al., 1998; Vorsa et al., 2002). The berries of European cranberry are one of thebest sources of phenolic compounds as compared with the other berry plants, such as strawberry,black currant, raspberry etc. (Moyer et al., 2002). The American cranberry has been increasinglyresearched for its health properties in recent years as well. Significant genetic variability was foundfor total phenolics, total anthocyanins, proanthocyanidins, soluble solids, quinic acid, citric acidetc. (Vorsa et al., 2002; Zeldin et al., 2007). At present large-fruited cranberries are successfullycultivated by amateur gardeners and even some commercial plantations are being established inLithuania. Nevertheless, the wild cranberry is more suitable for cultivation on harvested peat bogsas well as for their renaturalisation.Therefore, there is an evident need to conserve wild cranberries ex situ in order to complementtheir conservation in situ and facilitate the investigation and utilisation of this wild crop relative.The unique collection of genetic resources of the European cranberry was established at the KaunasBotanical Garden of Vytautas Magnus University with the purpose to preserve the most valuableclones. In consequence of their comprehensive evaluations the selection of five prospective cloneswas achieved.ConclusionsThe estimation of the berry yield and berry size indicated statistically reliable differences amongthe selected Lithuanian clones. The clone ‘Vaiva’ was characteristic of the highest yield.The largest damage was caused by the fungal dieseases Monilinia oxycocci, Fusicoccumputrefaciens, Botrytis cinerea, and Phyllosticta elongata. Berry rot diseases damaged about 5 – 15% of the berry yield.The berries of the European cranberry accumulated from 66.64 to 244.66 mg 100 g -1 ofanthocyanins and from 309.50 to 521.74 mg 100 g -1 of the total phenolics.References1.
