The hypersensitivity resistance of european plum to the <i>Plum pox virus</i> and its potential impact on the epidemiology of the virus
Abstract
Since the detection of the Plum pox virus (PPV) different strategies for Sharka containment were developed. One of the most important one is the breeding of resistant cultivars. Other than in Prunus persica and in Prunus armeniaca, in Prunus domestica a type of natural resistance was detected which seems to be able to prevent the spread of PPV both over long and short distances. Therefore, this type of Sharka resistance which is based on a hypersensitive response and has been stable for more than 20 years is suggested to have the most beneficial impact on the epidemiology of the virus compared to other mechanisms of resistance or tolerance.Keywords: Sharka containment, Prunus domestica, plum breeding
