More than 2,000 samples of weeds and cultivated crops were collected in Italy from areas where cucumber mosaic cucumovirus (CMV) epidemics occurred in 1988 and 1989. A collection of weeds was also made from fields neighboring the site of a 1989 satellite-mediated protection test of tomato. Samples were screened by molecular hybridization analyses, and CMV isolates were typed on the basis of their ability to hybridize with subgroup-specific riboprobes and with a satellite RNA-specific riboprobe. A strong relationship between CMV strain and disease type was found in tomato (.)
