Abstract: Eight strains of anthracnose pathogen, ZHG, WSX, ZTG, WHG, FTG, AHD, WRG and SLH were isolated from different tea cultivars in Fujian Province. These strains were identified by using morphological method and rDNA-ITS sequence analysis. The results showed that SLH strain was identified as Colletotrichum gloeosporioides, while the other seven strains were Colletotrichum fructicola, which has never been discovered on tea plant. The ITS sequences of C. fructicola and those of nine strains of anthracnose pathogen from tea-oil tree, jasmine plant and papaya (psidium guajave), were got for a clustering analysis. The results showed that base mutations or deletions were existed in the seven strains from tea plant, and the seven strains of C. fructicola were geneticly close to the pathogen C. gloeosporioides, isolated from tea plant, oil-tea plant and jasmine plant.
