Abstract: 57 isolates of Fusarium oxysporum f. sp. cubense Race 1（FOC Race 1） were collected from the 29 cities of Hainan,Guangdong,Fujian,Yunnan and Guangxi provinces and then inoculated onto tissue cultured plants of banana Fenjiao（Musa spp. ABB） by using root scratching inoculation method for assessment of their pathogenicity. The results showed that these isolates gave obviously differentiated pathogenicity,of which 32 isolates were highly pathogenic,23 isolates moderately pathogenic and 2 isolates weakly pathogenic,making up56. 14%,40. 35% and 3. 51% of the total isolates,respectively. The highly pathogenic isolates can be used as dominant ones for breeding of banana varieties tolerant to FOC Race 1.
