Effect of synthetic Nicotiana allopolyploids on resistance to Grapevine fanleaf virus (GFLV) strains F13 (left panels) and GHu (right panels). N. tabacum, N. benthamiana and the 2x(N. tabacum x N. benthamiana) amphihaploid (upper panels); and N. debneyi, N. clevelandii and 4x(N. debneyi x N. clevelandii) allopolyploid (lower panels) were tested for additive resistance.
