Identification and Evaluation of Resistance of Flue-Cured Tobacco with Different Genotypes to Fusarium Root Rot
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.
