CONICET scientists have developed and field-tested potatoes resistant to Potato Virus Y (PVY), which causes losses of between 20% and 80% of the crop depending on the severity of the infection. Field tests concluded that there was no PVY infection in the genetically-modified plants, while among those not modified, the rate of infection was 60-80%. Regulatory tests required by Argentina’s Ministry of Agriculture, Livestock and Fisheries to commercialize the transgenic potato are being carried out by the company Tecnoplant-SIDUS SA.
