Abstract: 8 flue-cured tobacco varieties compare test were carried out in the field after quarantine, and the varieties were introduced from Brazil and American. The comparison variety is K326. The results showed that the new flue-cured tobacco varieties of bud were the same as K326 except OX414 later. OX414 belong no flowing variety. All new varieties are free to blank shank and tobacco root nematode, and light infected Brown spot and TMV. OX414 has the highest yield, the next is NC72 “Primed”, the third is NC71. K326 has the highest Hectare production value, OX414 is the next, NC72 “Primed” is the third, and there was no remarkable difference between these new varieties. K326, NC100, NC72 “Primed” have the higher qualities and grade index. On the whole, K326, OX414, NC100, NC72 “Primed” are very good at yield, qualities, Hectare production value, grade index. But all of the economic index of Com and RGH61 are low.
