A large number of plant species were tested for susceptibility to six different viruses. Including plants shown to be susceptible by other workers, tobacco-necrosis virus infected 88 species in 37 families but failed to infect 25 species in 13 of these families and 28 species in 20 other families; tobacco-ringspot virus infected 143 species in 40 families but failed to infect 14 species in 13 of these families and 21 species in 16 other families; tomato-ringspot virus infected 54 species in 35 families but failed to infect 17 species in 12 of these families and 29 species in 20 other families; cucumber-mosaic virus infected 191 species in 40 families but failed to infect 21 species in 12 of these families and 25 species in 19 other families; cucurbit-mosaic virus infected 5 species in 1 family but failed to infect 107 species in 52 families; and alfalfa-mosaic virus infected 92 species in 28 families but failed to infect 16 species in 12 of these families and 43 species in 28 other families. The results indicate that ability of a plant to support increase of virus in its tissues is a characteristic of the species and, with respect to at least five of the six viruses studied, has little or no relationship to the taxonomic position of the family.
