Host range, symptomatology, and serology of isolates of potato virus Y (PVY) that share properties with both the PVYN and PVYO strain groups

Host range, symptomatology, and serology of isolates of potato virus Y (PVY) that share properties with both the PVYN and PVYO strain groups

American Potato Journal 73(7): 309-315

In surveys for the tobacco veinal necrosis strain of potato Y potyvirus (PVYN) in potato, 2 isolates (I-136 and I-L56) were obtained that shared properties with both the PVYN and the common (PVYO) strain groups. The isolates produced veinal necrosis on tobacco and mild symptoms on potato Jemseg, typical of PVYN but their symptoms on some other indicator species such as Capsicum frutescens, Chenopodium amaranticolor, Physalis angulata and P. floridana, were more typical of PVYO.
