Abstract
The studies were carried out to compare the chemical composition of fruit of chosen cultivars and clones of raspberries. Studied cultivars contained from 3.85 ('Chilcotin') to 5.94% ('Beskid') of sugars. The highest content of organic acids occurred in the fruit of cv. 'Pojedynek' (1.99%) and the lowest in cv. 'Chilcotin' (1.0%). The other fruit quality characteristic such as ascorbic acid ranged from 15.66 (for 'Rakieta') to 33.82 mg% (for 'Chilcotin'), respectively. 'Alangoin', 'Pojedynek', 'Elida' and 'Rakieta' were characterized by the highest level of anthocyanins (above 100 mg on 100 g f.w.). 'Cultivar' factor influenced the sugars, organic acids, ascorbic acid and anthocyanins content.
