Abstrakt
Seven populations of N. alata, 4 populations of N. sanderae and several hundred plants belonging to three generations of the hybrid (N. tabacum cv. TB-566 tetra × N. alata) × N. alata were tested for resistance to TSWV. Tested plants were artificial inoculated with TSWV under greenhouse conditions. Out of 11 accessions of N. alata and N. sanderae 7 were found to be composed entirely of plants hypersensitive to TSWV. In the remaining four accessions there were from 16 to 25% of TSWV susceptible plants. The hybrids (N. tabacum cv. TB-566 tetra × N. alata) × N. alata, regardless of their cytogenetical status, showed hypersensitive response to inoculation with TSWV...
