| 摘 要： | 采用采自云南省不同地点、不同生理小种的24株烟草野火病菌对24个不同烟草品种及两个野生种黄花烟和长花烟进行抗病性鉴定分析。结果表明,不同抗性品种对不同生理小种的抗性反应差异显著,根据接种后不同烟草品种的形成的病斑直径,将其划分为4个等级：高抗、中抗、中感、高感。辽烟15,G28对于烟草野火病菌0,1号生理小种均表现为高感,而云南省大面积栽培的K326、红花大金元、云烟87等对于两个生理小种均表现为中感,而两个野生种黄花烟和长花烟均表现为高抗,可以作为烟草野火病抗性育种优先利用的种质资源。

| Abstract: | A total of 24 tobacco cultivars and two wild tobaccos (Nicotiana longiflora Cav and Nicotiana rustica) were analyzed to study their resistance to tobacco wildfire by inoculated different physiology races of Pseudomonas syringae pv. tabaci. The result indicated that the resistance of different tobacco cultivars was significantly correlated with different physiology races. The 24 tobacco cultivars and two wild tobaccos were divided into 4 levels according to diameter of spot, that is high-susceptibility, middle-susceptibility, middle-resistance and high-resistance. Liaoyan 15 and G28 are high-susceptibility to physiology race 0 and 1. K326, Hongda and Yunyan 87, which are main planting cultivars, are middle-susceptibility. The two wild tobaccos were high-resistance, which should be given priorities in tobacco wildfire-resistance breeding. |
