GENETIC VARIABILITY OF \u3ci\u3eColletotrichum lindemuthianum\u3c/i\u3e BY SEQUENCING ITS REGIONS

INTRODUCTION Anthracnose, caused by Colletotrichum lindemuthianum, is one of the most important diseases of the common bean (Phaseolus vulgaris L.) in Brazil and in other regions of the world (Pastor-Corrales et al. 1994). Anthracnose occurs more severely in places where relative humidity conditions above 91% and temperatures ranging from 18° and 22°C predominate (Kelly et al. 1994). High genetic variability of C. lindemuthianum has been described worldwide, and more than 247 different races of the pathogen have been identified, which 35 occur exclusively in Brazil (Nunes et al. 2013). The high number of physiological races and the complexity in the use of genetic resistance of the C. lindemuthianum fungus are evidence of wide virulence diversity (Pastor-Corrales et al. 1994). Therefore, the objective of this work was to characterize isolates of C. lindemuthianum from Pernambuco state of Brazil through sequencing of ITS regions
