摘要

The use of resistant cultivars is considered to be the most efficient solution to control Plum pox virus (PPV). The identification of new potential sources of PPV resistance in plum germplasm remains important for the future development of new cultivars due to the paucity of naturally occurring resistance reported so far. Two plum selections named 'Local de Dragasani' and 'Dunarea albastra' respectively, grown within the experimental plum orchard with high inoculum pressure with PPV-D and PPV-Rec strains, have remained PPV free during a period of 17 years. When artificially inoculated in greenhouse conditions with PPV-D or PPV-Rec, a typical hypersensitivity response was observed on 'Local de Dragasani'. Because the effectiveness of hypersensitivityagainst PPV is still under controversy, additional studies are requested. The behavior of 'Dunarea albastra' under high natural inoculum pressure with PPV also showed a particular interest. Is this selection a potential candidate for PPV resistance? Artificial inoculation needs to be performed to obtain pertinent conclusions. Studies on resistance to PPV of the two plum selections are going to be expanded.
