| Abstract: |
| 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. |
