Conteúdo: | Anthracnose caused by Colletotrichum lindemuthianum is one of the important deiseases in common beans (Phaseolus vulgaris L.). This research aimed at studying the Colletotrichum lindemuthianum in Paraná state region, Brazil, using race identification through differential cultivars. Nine races were identified from the eighteen isolates assessed: 7, 31, 65, 69, 73, 81, 87, 89 and 95. It was further observed that the Dark Red Kidney, Cornell 49242 and Mexico 222 cultivars were susceptible to races 7, 31, 87 and 95, races 31, 73, 89 and 95 and races 65, 69, 73, 81, 87, 89 and 95, respectively. Cultivars AB 136, carrier of the Co-6 gene and cultivar G 2333, carrier of the Co-42, Co-5 and Co-7 genes, were resistant to the identified races. These results showed the pathogenic variability and the importance of monitoring Colletotrichum lindemuthianum and resistant bean plant cultivars.
