Abstract
Three cvs. of canna in commercial horticultural greenhouses in Minnesota showed foliar chlorotic and necrotic mottle and streaking symptoms similar to those described for canna yellow mottle in Japan.
Non-enveloped bacilliform particles 31 nm in diameter and averaging 130 nm in length were always associated with yellow mottle symptoms.
The canna bacilliform virus was not related to any of 6 other viruses of similar morphology.
Because the canna bacilliform virus was frequently found in mixed infections with cucumber mosaic virus and/or a potyvirus, assumed to be canna mosaic virus, its exact role in the etiology of the disease remains to be clarified.
