图2 基于362个F2单株(红花大金元×Beinhart1000-1)的烟草赤星病抗性QTL定位结果 图中每条连锁群的左右两侧分别为遗传距离(厘摩尔)和标记名称, 其中, 红色标记表示位于Bindler等[30,31]公布的连锁群上。

Fig. 2 QTL mapping of tobacco brown spot (TBS) resistance based on 362 F2 individuals derived from the cross HD × Beinhart-1000 In each linkage group, the positions (cM) and names of markers were shown on the left and right side, respectively. The red markers were mapped in the genetic map constructed by Bindler et al. [30,31]
