From: Allopolyploidy and the evolution of plant virus resistance
Infection frequencies in inoculated and apical leaves of populations of plants tested for resistance to Grapevine fanleaf virus (GFLV) strains GHu and F13, and Tomato ringspot virus (ToRSV) strain AP. The percent virus incidence is indicated for inoculated and apical leaves. Asterisks (*) after plant names indicate that the inoculated leaves in the plant-virus combination were not tested.
