METHODS FOR DETECTING ISOLATES OF THE POTATO VIRUS Y (PVY) RESPONSIBLE FOR NECROSES

摘要

The invention concerns a method for detecting the PVY virus which consists in a SNP test or an extension reaction specific to mutations corresponding to R/K400 et D/E419, the presence of at least one of said mutations indicating the presence of at least one virulent PVY strain capable of causing necrosis in plants of the Solanaceae family, in particular in potatoes.
