Abstract
In four ornamental Physalis species 38 new experimental host-virus relations have been detected.
After mechanical inoculation with 19 viruses from 12 virus groups Physalis alkekengi proved to be locally and systemically susceptible to 10 viruses, P. ixocarpa to 14 viruses, P. peruviana to 4 viruses and P. pubescens to 2 viruses.
In the case of Physalis alkekengi inoculated with broad bean wilt Fabavirus (BBWV) and P. peruviana inoculated with alfalfa mosaic Alfamovirus (AMV), potato aucuba mosaic Potexvirus (PAMV), potato Y Potyvirus (PVY) only systemic vein clearing and mosaic were established. Physalis ixocarpa proved to be only locally susceptible to tobacco necrosis Necrovirus (TNV), P. peruviana to tobacco rattle Tobravirus (TRV) and P. pubescens to TNV and TRV.

Physalis ixocarpa proved to be only locally susceptible to tobacco necrosis Necrovirus (TNV), P. peruviana to tobacco rattle Tobravirus (TRV) and P. pubescens to TNV and TRV.
In those cases the perennial ornamental Physalis species were found to be infected systemically, it is likely that natural infections with these viruses also occur.
