摘　　要：采用十二孔板法、培养皿小苗法、注射接菌法及菌液灌根法,以病情指数和烟苗危害症状为主要评价指标,对贵州省12个烤烟(Nicotiana tabacum L.)品种(系)进行抗烤烟青枯病[Ralstonia solanacearum(Smith)Yabuuchi et al]鉴定和评价。结果表明,十二孔板法和培养皿小苗法不能反映烤烟的真实抗性,注射接菌法对试验操作要求较高,菌液灌根法鉴定结果较为准确。所测12个品种(系)中达到高抗水平的有贵烟1号、贵烟14号和抵字101,中抗水平的有K346、K326、岩烟97、贵烟6号、贵烟8号和贵烟9号,敏感水平的有红花大金元、长脖黄和南江3号。Four different methods including 12-well plate seedlings method, Petri dishes seedlings method, Petri dishes seedlings method, injection inoculation method and irrigating inoculation method were used to analyze the tobacco bacterial wilt resistance of 12 different varieties of flue-cured tobacco cultivars. Among all 12 flue-cured tobacco cultivars （lines）, three cultivars including Guiyan No.l,Guiyan No.14 and D101 had high resistant level. Resistant levels from were low to mid- dle in the order of K346, K326, Yanyan 97, Guiyan No.6, Guiyan No.8 and Guiyan No.9. Sensitive cuhivars included Honghuadajinyuan, Changbohuang and Nanjing No.3.
