Abstract
Fusarium oxysporum f. sp.cubense from Hainan province of South China was identified by colony morphology on modified Komada medium (K2 medium). Forty isolates ofF. oxysporum f. sp.cubense obtained from Cavendish cultivars sampled at random from 20 banana farms of Hainan province, China, formed laciniated colonies on modified K2 medium. None of the isolates ofF. oxysporum f. sp.cubense sampled from 10 Gros Michel cultivars in five other banana farms in Hainan with the same method and six other species ofFusarium conserved in our laboratory formed laciniated colonies on the same medium. The results showed that it is a simple, fast and reliable method for identifyingF. oxysporum f. sp.cubense Race 4.
