摘　　要：为明确不同基因型烤烟对烟草镰刀菌根腐病的抗性,利用10个烟草品种(系),采用粗毒素幼芽接种、带菌菌谷接种、孢子悬浮液培养等方法进行抗性鉴定。结果表明,供试品种对尖孢镰刀菌抗性表现出显著差异;对尖孢镰刀菌表现出抗的品种(系)有4个,分别是‘Y2001’、‘Y2002’、‘长脖黄’、‘664-01’;对尖孢镰刀菌表现出感的品种(系)有6个,分别是‘7710’‘、7713’‘、Y2007’‘、Y2008’‘、中烟100’、‘小黄金1025’。3种接种方法鉴定结果基本一致,共筛选出4个抗性品种(系)。In order to clarify the resistance of flue-cured tobacco with different genotypes to Fusarium tobacco root,the resistance was identified by crude toxin stress culture,inoculation of grain culture with fungi,and spore suspension culture.The results showed that the test varieties showed significant differences in resistance,‘Y2001’,‘Y2002’,‘Changbohuang’,and‘664-01’showed resistance to Fusarium oxysporum,and‘7710’,‘7713’,‘Y2007’,‘Y2008’,‘Zhongyan 100’and‘Xiaohuangjin 1025’showed susceptibility to F.oxysporum.The identification results of the three inoculation methods were basically consistent,and a total of 4 resistant varieties(lines)were screened.
