Abstract

Between Amaranthus mitchelii, a plant unkown for plant virology, and the hardly known A. mangostanus and A. quitensis on the one hand, and 12 viruses on the other hand, 36 compatible host-virus relations were detected, of which 5 were local, 22 local and systemic. In nine cases incompatible realations were pointed out. Local and sytemic relation was established between all the three Amaranthus species and belladonna mottle virus, broad bean wilt virus, cucumber mosaic virus, potato virus X, potato virus Y, tobacco ringspot virus and tomato mosaic virus, as well as between Amaranthus quitensis and henbane mosaic virus. Local host-virus relation was found between Amaranthus mangostanus and beet necrotic yellow vein virus and tobacco rattle virus, A. mitchelii and beet necrotic yellow vein virus and A. quitensis and beet necrotic yellow vein virus as well as tomato aspermy virus. Incompatible relation was pointed out between Amaranthus mangostanus and henbane mosaic virus, tomato aspermy virus, zucchini yellow mosaic virus; A. mitchelii and henbane mosaic virus, tobacco rattle virus, tomato aspermy virus, zucchini yellow mosaic virus; and between A. quitensis and tobacco rattle virus as well as zucchini yellow mosaic virus.
