Potatoes are the third most important food crop in the world after rice and wheat, and their production as food is constantly increasing with the increase in the size of the human population. One of the factors that strongly influence the yield and quality of production are viral diseases that cause great damage to potato growers. More than 50 different viruses have been reported infecting potatoes which are a problem for the quality and the quantity of global potato production. Some of the most common in potato crops and most economically important viruses are Potato virus Y (PVY), Potato leaf roll virus (PLRV), Potato virus X (PVX), Potato Virus A (PVA), Potato virus S (PVS), and Potato virus M (PVM). The identification and characterization of these viruses is crucial for the diagnosis, prevention, and control for potato growers around the world. Selection of resistant to viruses on potato cultivars, introduction of certification schemes for virus-free planting material, and different control measures are irreplaceable and obligatory for guaranteeing the quality and yield of potato production.
