The study of the phenotyping process of some Romanian cherry genotypes

The Plum pox virus (PPV), is considered to be particularly serious in stone species, has appeared research and documents since 1915 from which revelations emerge about the first symptoms appearing orchards central eastern Europe, where (PPV) being so viral, it caused production losses species such as plum, nectarine, cherry, almond, sour nectarine last but not least apricot, were 100%. creation of new varieties with natural genetic resistance remains one most solid ways limit spread this quarantine virus. Elisa serological technique molecular PCR offer possibility highlighting presence or absence plant. present study illustrates results phenotyping tests (indexing on different rootstocks, PCR) for some autochthonous cherry genotypes. Even if difficult establish a definitive hypothesis regarding control we still observe an important number graft/rootstock combinations, as: Margarit / Otesani 11, Mari de Malu Rosu Mai/ showed artificial infection These genotypes are interest future breeding works.
