Dataset for: Standard Evaluation Trial for Potato Virus Y
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Potato virus Y (PVY) is responsible for serious yield losses worldwide. 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 ' . Please return only a json list of at most 3 Keywords corresponding to the Description:.<|eot_id|><|start_header_id|>assistant<|end_header_id|> {"Answer" : ["Potatoes","Potato Virus Y"]} <|eot_id|>
