‘Sampo’ and ‘Samdal’, Elderberry Cultivars for Juice Concentrates

Abstract

In 1989-95 two field experiments with eight Danish and three foreign cultivars of elderberry, Sambucus nigra, L. were carried out with the objective of comparison of yield, umbel weight and the contents of anthocyanin, soluble solids and titratable acid.

To obtain a high economic value per hectare and in order to keep the manual picking costs at a minimum, the fruit yield and umbel weight were used as the most important criteria for selection of cultivars with high contents of anthocyanin and soluble solids which are necessary for processing of high quality fruit concentrates.

Compared to ‘Sampo’ and ‘Samdal’ the yield, umbel weight and content of anthocyanin of ‘Allesoe,’ and ‘Korsor’ were significantly lower, but the content of soluble soh'ds were high in ‘Korsor’ and low in ‘Allesoe.’ By growing of ‘Sampo’ it is possible to obtain a high yield, medium size umbels, high content of anthocyanin and medium content of soluble solids. With respect to yield and content of anthocyanin the differences between ‘Sampo’ and ‘Samdal’ were not significant. Compared to ‘Sampo’ the cultivar ‘Samdal’ had a higher umbel weight but a lower content of soluble solids and titratable acids.
