| Abstract: | Observations from 1982 to 1988 showed that two tobacco breeding strains, GAT-2and GAT-4, were resistant strongly to tobacco TMV disease, and more tolerant to CMVdisease. When backcross technique was used to transfer their 5 pairs of CMV-tolerantgenes, two significant points should be emphasized. In the populations of their F_2 andthe F_2 from every backcross generations, the plants with 5 pairs of CMV-tolerant genesshould be picked out and hybridized back to the recurrent parent. During inoculationexaminating, a considerably great number of inoculum populations should be applied. Thesymbolizations for selecting plants with 5 pairs of CMV-tolerant genes were as follows: af-ter seedlings were inoculated with TMV, those plants which showed N-type necroses orsystematic infection were removed. The rest were reinoculated with CMV and thensymptomless plants were those with 5 pairs of CM V-tolerant genes. |
