The resistance of 15 flue-cured tobacco varieties were identified by artificial inoculation of black shank. The results showed that K326, Yunyan 202 and NC102 belonged to resistance variety against black shank, and the resistance successively were K326 〉 Yunyan 202 〉 NC102 ; Yunyan 87, Cuibi 5, Yunyan 85, Yunyan 97 and Cuibi 7 belonged to moderate resistance variety against black shank, and the resistance successively were Yunyan 87 ~ Cuibi 5 ~ Yunyan 85 〉 Yunyan 97 〉 Cuibi 7 ; Cuibi 12, NC82, PYH06 and Cuibi 14 belonged to moderate susceptible variety against black shank, and the resistance successively were Cuibi 12 ~ NC82 ~ PVH06 ~ Cuibi 14; Cuibi 1 and Hongda belonged to high susceptible variety against black shank, and the resistance successively were Cuibi 1 〉 09011 〉 Hongda. The disease dynamics of flue-cured tobacco varieties were positively correlated with variety susceptibility, namely the earlier infection in susceptible variety, the faster the disease progression.
