Conteúdo: | Anthracnose, caused by Colletotrichum lindemuthianum, is one of the most destructive diseases to affect the common bean (Phaseolus vulgaris). Cultivar G 2333 is one of the most resistant cultivars, being the donor parent of genes Co-42 and Co-5 in the pyramiding breeding programme of BIOAGRO/UFV. This study aimed to: (a) develop resistant homozygous 'carioca-type' common bean lines separately carrying the Co-42 and Co-5 genes derived from G 2333, with the marker assisted selection (MAS), and (b) characterize resistant lines with different pathotypes of C. lindemuthianum. Thirteen lines of the 'carioca grain type' were selected; 10 carrying the Co-42 and 3 the Co-5 gene, all showing resistance to the anthracnose pathotypes tested in this work. The association of adapted lines with the Co-42 gene combined with other resistance genes should provide durable resistance to this disease in Brazil and in other parts of the world.
