Anthracnose is one of the main soybean diseases and is caused mainly by the fungus Colletotrichum truncatum. The identification and distribution of species of genus Colletotrichum in different soybean producing regions in Brazil is fundamental to understand the disease epidemiology and to ensure success of control strategies. A polyphasic approach was used to characterize 51 pathogen isolates collected between 1992 and 2007 in different regions in Brazil using molecular, morphological and pathogenic analyses. Phylogenetic analyses based on Bayesian inference of partial sequences of genes GAPDH, HIS3 and ITS- 5.8S rDNA region showed the sole occurrence of species C. truncatum. The intraspecific genetic diversity of the isolates was also examined with the construction of a haplotype network, revealing considerable variability degree with 27 haplotypes in the collection and several of them identical to isolates of C. truncatum from other regions around the world. The pathogenic characterization showed high variation in aggressiveness in both methods, mainly CMES1075, CMES1080 and CMES1059 isolates for causing greater damage to the seedling stem and higher commitment to the development of inoculated soybean seeds. The presence of C. truncatum species associated to anthracnose in soybean in the collection of isolates investigated, with relevant genetic and pathogenic variability, indicates that C. truncatum was the causal agent of the disease in Brazil until 2007 with wide geographical origin and high pathogenic potential.} }
