The research was conducted in the years 2010–2012 at the Fruit Farming Laboratory of the West Pomeranian University of Technology, Szczecin. The study involved blackcurrant cultivars of ‘Ben Alder’, ‘Sofijewskaja’ and ‘Tisel’ and consisted in the comparison of their respective fruit size and firmness, chemical composition, colours according to the size of fruit. After harvest yield was immiedately divided into small (<13 mm) and large fruits (>13 mm). From among of researched cultivars ‘Tisel’ characterised the major fruits; the large fruits in total yield was 79%, and the average weight of 100 of these fruits was 205 g. It was found that the small fruits of all tested cultivars were firmer (212 G mm) and less susceptible to damage (101 G mm) than large fruits (71 G mm). Among the tested varieties the most firm fruits were of ‘Ben Alder’ (234 G mm). Small fruits were also characterised by a higher acidity (3.24 g), lower pH of juice (3.24) while a higher content of vitamin C (182 mg). Small fruits were also darker and had darker pulp – parameter L*.
