The biologicalpeculiarities of cranberrybush cultivars and clones were estimated according to the usual methodsof the evaluation of horticulture plants. Reliable differences were determined between accessionswith respect to productivity, the number of fruit per cluster and the mean weight of the fruit. Theinvestigations of the biochemical composition of the fruit of different cultivars and clones revealedsignificant differences in the amounts of phenolic compounds (anthocyanins and flavonols),benzoic, and ascorbic acids. The accession of Lithuanian origin P1 was typical of the largestamount of ascorbic acid (46.1 mg 100 g -1 ). The fruit of the cultivar ‘Leningradskaja Otbornaja’accumulated the largest amounts of anthocyanins. The cultivars ‘Krasnaja Grozd’ as well as theclone P2 had the largest benzoic acid amounts. The value of the most productive Europeancranberrybush accessions were determined by the number of fruit in a cluster. The results of thebiochemical investigations corroborated that the selection of European cranberrybush accessions inrespect to benzoic acid, anthocyanins and ascorbic acid amounts could be advisable.KopsavilkumsIzmēăinājumi tika veikti irbeĦu (Viburnum opulus L.) kolekcijas stādījumā Vitauta Magnusuniversitātes KauĦas botāniskajā dārzā no 1999. līdz 2005. gadam.

(European cranberrybush), V.trilobum Marsh. (American cranberrybush) as well as V. sargentii Koehne are widely used intraditional and folk medicine. The European cranberrybush (Viburnum opulus L.) is a native plantin Lithuania which is widely used in traditional and folk medicine. Its flowers, bark and leaves arean important medicinal raw because it possesses large amounts of the tanic substances, carotenoids,isovalerianic acid, saponines, and glycosides. The seeds contain up to 21 % of fatty oil (Bock et al.,1978). Fruit of this species accumulate significant amounts of biologically active substances. The18
