Abstract

The goal of this research was to evaluate the behavior of 10 potato varieties (with different starch content) after mechanical inoculation with a PVYNTN isolate. Excepting the varieties Christian, Riviera, and Bellarosa, which were very resistant and resistant to this pathogen, all the other varieties presented 62.5-100% infected plants. After 5 months from harvesting, the frequency of tubers with necrotic symptoms was between 2.2-27.4% for varieties Bellarosa, Jelly, Roclas and 62.6-97.8% for Desiree, Productiv, Red Lady, Carrera, and Hermes. The tubers from samples with significantly higher starch content (varieties Riviera and Christian), after harvest and storage, didn’t have visible tuber necrotic disease symptoms.
