Seventeen isolates of strawberry anthracnose were obtained from Shanghai *** to the temperature test for mycelial growth,these isolates were divided into two groups: one was strain CMf-04 with optimal temperature of 24℃,the other was including 16 strains with optimal temperature of 28℃,and most of which could produce sexual stage on PSA media,*** of CMf-04 were hyaline,unicellular,straight and fusiform,(12.1-16.4)μm×(3.6-5.4)μ*** of QPg-961 were hyaline,unicellular and ovoid to oblong,(13.0-19.7) μm×(4.1-7.3)μ*** basis of morphologcal,biological characteristics and the sequences of ribosome rDNA ITS,isolate CMf-04 from the strawberry rotten fruits was identified as Colletotrichum acutatum;while all the other isolates from the diseased leaf stalks,runners and root crowns at strawberry plantlet propagation stage were belonged to Colletotrichum *** proved that *** was the main pathogen of the strawberry anthracnose in summer strawberry propagation fields in Shanghai and it is of significance for the breeding of resistant strawberry and its control.
