Abstract:
The farmers income is affected strongly by potato virus diseases. Potato Virus Y has become in the last years one of the
most damaging pathogen of potato crop. It can cause serious reduced yield, stand loss and decrease of the tuber’s
quality. The necrotic and recombinant strains PVY play an important rol in the spreading of this virus. Elimination of
this pathogen from potato supply is essential for seed production and the choice of resistant varieties to the infection
with this virus could be one of the measures recommended for farmers and producers. The results of this preliminary
study show that varieties resistant to necrotic strains PVY in our study (samples taken from theregionsBraşov, Covasna,
Harghita, Cluj, Suceava, in 2014) were the following: Riviera, Bellarosa, Jelly, Roclas, Christian.
