Pollination and fruit set in raspberries

, : Pollination and fruit set in raspberries. Acta Horticulturae (60): 169-175

The red raspberry cvs Norna and Asker and the selection II-2LGP were pollinated by several pollinators. Norna gave a low fruit set after selfing compared with cross pollination. The best pollinators were Preussen, Malling Jewel and Glen Clova. Emasculation reduced fruit set in open-pollinated flowers of Norna. Flowers of this retained their ability to set when open-pollinated within 3 days of isolation and emasculation but after 6 days the set was very low.
