Enzyme-linked immunosorbent assay (ELISA) was used to evaluate the incidence of prune dwarf virus (PDV) antigen in seed and seedlings derived from nine open-pollinated, spontaneously PDV-infected blackthorn (Prunus spinosa L.) shrubs. The incidence of PDV antigen in seed lots gathered from the different seed source shrubs ranged between 93.6 and 100%. In seedling progenies arised from seeds harvested from four of those PDV-infected blackthorn shrubs, the rate of plants carrying PDV antigen, however, was ascertained to be 0% in three progenies and 4.8% in one progeny. PDV-infected blackthorn seedlings up to four leaf stage showed neither growth depression nor any other disease symptoms.
