| 中文摘要: |
| 为了充分发掘并利用烤烟抗赤星病优异种质资源，寻找新的烤烟赤星病抗源，扩大赤星病抗
病育种可用亲本的遗传基础，对不同来源的390 份烤烟种质资源赤星病抗性进行系统的鉴定研究。结果表
明：在不同来源的烤烟种质资源中，61 份贵州省内地方品种抗赤星病种质资源共有10 份，分别为晓丰8
号、湄潭-2、黔江1 号、大方自留种、YA-2、惠水-1 、惠水-2、福泉-2 、福烟6 号和YQ-1；90 份贵州省
内育成品种中只有紫江一号具有赤星病抗性；105 份贵州省外引进的种质资源中有10 份种质资源具有抗病
能力，分别为云烟100、云烟110、单育2 号、中烟86、大白筋599、许金4 号、龙江911、辽烟8100、净叶黄
和潘园黄；134 份国外引进品种中只有Coker spedlgred 和Oxford 26 两份抗赤星病种质资源。可见，贵州省
内地方品种中抗赤星病种质资源最为丰富，可以作为新的烤烟赤星病抗源。 |

| In order to explore and utilize flue-cured tobacco germplasm resources resistant to brown spot
disease，screen new resistant resource and broaden genetic basis of parents for tobacco brown spot resistance
breeding，resistance to brown spot disease of 390 tobacco germplasm resources from different sources were identified
in the present study. The results showed that 10 flue-cured tobacco germplasm resources were resistance to brown
spot disense from 61 local cultivars in Guizhou，which were Xiaofeng No. 8，Meitan-2，Qianjiang No. 1，Dafang，
YA-2，Huishui-1，Huishui-2，Fuquan-1，Fuyan No.6 and YQ-1，respectively. Only one germplasm Zijiang No.
1 from 90 cultivars bred in Guizhou had resistance to brown spot disease. Among 105 introduced varieties outside
Guizhou province，ten of them including Yunyan 100，Yuanyan 110，Danyu No.2，Zhongyan 86，Dabaijin 599，
Xujin No.4，Longjiang 911，Liaoyan 8100，Jingyehuang and Pangyuanhuang were detected resistant to brown spot
disease. Two germplasm Coker spedlgred and Oxford 26 of 134 introduced varieties abroad had resistance to brown
spot. In conclusion，flue-cured tobacco germplasm resources resistant to brown spot disease are most abundant in
local cultivars in Guizhou，which can be used as new resistant resources for tobacco brown spot resistance breeding. |
