Pollen quality was assessed with cotton blue staining in an apomictic blackberry, Rubus nessensis W. Hall, on plants grown outdoors in a random arrangement under uniform conditions. Significant variation between populations may be attributed mainly to genetical factors. Most of the variation found between plants, sometimes even between ramets, within a population must, however, be environmentally caused, likewise the variation between flowers within the same plant.
