Potato is a vegetatively propagated important food crop. However, it is affected by many fungal, bacterial and  viral pathogens that deteriorate tuber quality and reduce yield. The manifestation of latent virus infection of  potato seeds into the grown crop also causes high economical loss to the potato seed producers and crop  growers. The management of such problems depends on the timely identification of diseased or defective  seed tubers, seeds, and crop samples to produce high quality seeds, potato tubers, and reduce crop losses.
