SUMMARY The titres obtained in microprecipitin tests with purified preparations of pepino latent virus (PepLV) and the Andean strain of potato virus S (PVS A ) using PepLV antiserum and two antisera to the ordinary strain of PVS (PVS°) indicated a close serological relationship between PepLV and PVS A . Using antiserum to PVS°, both viruses were detected by ELISA when infective Chenopodium quinoa sap was diluted to 10 ‐5 but not to 10 ‐6 . Particles of both viruses were decorated equally well by antibodies to PVS o , PVS A and PepLV in all virus‐antiserum combinations. When PepLV was inoculated to C. quinoa, C. amaranticolor and potato plants, the symptoms induced closely resembled those of PVS A in these hosts. It is concluded that PepLV is an isolate of PVS A from pepino.
