This work describes the incidence and distribution of the most important potato viruses which causes a limiting factor for sustainable production of potato in China since 2009.During this period, Potato viruses (PVX, PVY, PVS, PVM, PLRV and PVH that is a new calarvirus identified by our laboratory recently) were consistently the most prevalent pathogens.Infections of potato plants were determined using RT-PCR and western blot assays.Field samples from Yunnan, Shinjang, Heilongjiang and Inner Mongolia Provinces, the incidence of virus infections were between 42.8 % (Heilongjiang),52.1% (Inner Mongolia), 66.6% (Shinjang) and 74.1% at Yunnan province.
