The results are as follows. To TMV, 21 germplasms were immune, one was resistant, 30 were medium resistant, 130 were medium sensitive and 20 were sensitive. To CMV, 4 were resistant, 20 were medium resistant, 79 were medium sensitive and 99 were sensitive. To PVY, one was immune, 2 were resistant, 33 were medium resistant, 96 were medium sensitive and 70 were sensitive. For superior quality and resistance, Baisezhong (flue-cured tobacco), Big るま(sun-cured tobacco) and KoKulu izmir (oriental tobacco) can be used directly. The other germplasms including 8301 and Huangjind
