Dataset for: Standard Evaluation Trial for Potato Virus Y
Listed in International Potato Center
Potato virus Y (PVY) is responsible for serious yield losses worldwide.
Description
Potato viruses are small transmissible pathogens which use components of host plant cells to multiply. PVY is easily transmitted by aphids as non-persistent transmission way.
Until now three different types of resistance have recognized: Extreme resistance, hypersensitive and relative resistance. Plants infected by PVY will present symptoms of leaf bunching and crinkling, mild or strong leaf mosaic, necrotic veins, leaf spots, and leaf drop. Field evaluation trials for relative resistance requires the testing material to be exposed to virus infection during two seasons in a location and season of high aphid population and virus incidence.

The evaluation per se takes place during the third season under identical conditions of exposure to the virus. Control varieties are used to verify the efficiency of the inoculum and infector plants to spread the viruses. The extreme resistance test is conducted under greenhouse conditions to complement the whole set of evaluations.
A total of 387 advanced clones divided into 7 Subset was evaluated until now showing the percentage of field infection and extreme resistance results turning out on six levels of resistance: Hypersensitive, highly susceptible, susceptible, resistant and extreme resistance. The interpretation of these evaluations provides important information to guide potato breeding and selection programs, as well as for the recommendation of varieties for specific uses.
