Abstract
Myzus persicae (Sulz.) transmitted a second component virus from a turnip latent virus complex to healthy Physalis floridana Rydb. seedlings after passage of the complex through turnip (Brassica rapa L.). The symptoms were small yellow specks on the leaves which became more pronounced on new growth when infected plants were cut back. Combined transmissions with the first component, mild chlorosis virus, produced yellow-net symptoms characteristic of the complex.The second component was transmitted from P. floridana to P. floridana by graft and of six aphid species tested, only M. persicae transmitted it. The first component alone was transmitted from the complex by M. circumflexus (Buckton). Only a few plants developed symptoms of the second component after inoculation by aphids, and data from some tests indicated that infected P. floridana may sometimes be symptomless. Both components were transmitted in the persistent or circulative manner and were not sap-transmissible.
