dc.description.abstract	The wide pathogenic variability among and within races of Colletotrichum lindemuthianum has complicated the process of obtaining cultivars of Phaseolus vulgaris that are resistant to anthracnose. Six isolates were inoculated into twelve differential cultivars and seven commercial cultivars of the common bean at concentrations in the range 102 to 106 spores mL-1 . Information concerning the vertical and horizontal resistance of hosts and the virulence of isolates was obtained from diallel analysis. It was clear that the set of differential cultivars recommended for the determination of races of C. lindemuthianum is inefficient in detecting differences within race 65, and it is suggested that new sources of resistance should be identified and added to the cultivar set. There were significant differences in the virulence of isolates from race 65, with isolates CL 837 and CL 844 being the most virulence. No horizontal resistance was detected in the C. lindemuthianum-common bean system.	pt_BR

dc.description.resumo	A ampla variabilidade patogênica entre e dentro de raças do Colletotrichum lindemuthianum tem dificultado o processo de obtenção de cultivares de Phaseolus vulgaris resistentes à antracnose. Seis isolados foram inoculados em 12 cultivares diferenciadoras e sete cultivares comerciais de feijão nas concentrações de 102 a 106 esporos mL-1. Informações a respeito da resistência vertical e horizontal dos hospedeiros e da virulência dos isolados foram obtidas a partir de análises dialélicas. Constatou-se que o conjunto de cultivares diferenciadoras recomendado para a determinação das raças de C. lindemuthianum é ineficiente em detectar diferenças dentro da raça 65, e isto sugere que novas fontes de resistência devam ser identificadas e adicionadas a esse conjunto de cultivares. Houve diferença significativa na virulência dos isolados da raça 65, sendo os isolados CL 837 e CL 844 os mais virulentos. Não foi detectada resistência horizontal no patossistema C. lindemuthianum-feijoeiro.	pt_BR
