To select suitable planting flue-cured tobacco varieties with highly resistance to bacterial wilt in Wenshan Prefecture,through field plot experiment in Guangnan County and Malipo County,we comprehensively analyzed the agronomic traits,disease resistance,economic characters,chemical composition and sensory quality of five main traits (K326,Yanyan 97,PVH2254,Anyan No.2 and Yunyan 87) with good disease resistance. The results showed that,in Wenshan Prefecture,Yanyan 97 possessed the best bacterial wilt resistance,its incidence was only 0.9% (Guangnan) and 6.0% (Malipo), it had good agronomic traits,its economic characters (the per unit yield increased by 32.8% and output value per unit area improved by 33.0%) and score of sensory quality were at a high level,in addition,its chemical composition of coordination was relatively good. The secondly performance of varieties was PVH2254 and Anyan No.2,followed by K346. Preliminary study showed that Yanyan 97 and Anyan No.2 were more suitable for planting in areas prone to bacterial wilt in Wenshan.
