Plum pox is a serious worldwide problem with a severe impact on the productivity and quality of Prunus fruits (PPV), a virus against which no chemical or biological curative treatment is available. Infections of susceptible plants cause a hormonal disruption in which antagonist hormones are induced simultaneously, while in resistant varieties, the accumulation of antagonist hormones shows a sequential pattern. Identifying key factors underlying the spread of disease is an essential but challenging condition for delivering management strategies. Identification of new genotypes of natural genetic resistance to Sharka; the study of the genetic mechanisms behind the expression of these characters and alternative methods of limiting the propagation of this quarantine virus are objectives of interest in finding longterm solutions to limit propagation of this virus. The Romanian peach varieties 'Alexia’, 'Triumf’, 'Alex’ and 'Flacăra’ following the Elisa serological tests proved negative at PPV in conditions of natural infection in the field.
