Abstract:
Fruit set and yield of the following cultivars of black currant (Ribes nigrum L.): 'Ben Alder', 'Ben Lomond', 'Ben Nevis', 'Ben Tirran', 'Ceres', 'Ojebyn', 'Titania' and 'Triton' were investigated in 1994-1996. Percentage fruit set, size of berries and yield of all investigated cultivars were higher when much foraging activity of pollinating insects was observed. The bushes on open-pollinated plots set more fruit (50-200%), had bigger fruits (10-20%) and gave higher yields (60-300%) than plants isolated from insects. All eight cultivars, including 'Titania', had lower fruit set when pollinated with their own pollen under nets than when subjected to free pollination in open plots.
