Conteúdo: | Aiming at the identification of common bean lines with anthracnose (Colletotrichum lindemuthianum) resistance, 256 lines obtained from the backcrossing programme of the donor parent G2333 with the recurrent parents ESAL 696 and CI 140 were used. G2333 is a carrier of the alleles Co-42, Co-5, and Co-7 but has several unfavourable phenotypes such as type IV growth habit, red grains and photoperiod sensitivity These lines were inoculated with the three races 2047, 1545, and 73. In the lines with allele Co-42, resistant to race 2047, we could not identify other resistance alleles, although Co-5, Co-7 or both might be present in some of them. In the lines without allele Co-42 (susceptible to race 2047) and inoculated with the races 1545 and 73, some lines were identified with pyramid Co-5 and Co-7, some with Co-5 only, and others with Co-7 only. Lines carrying allele Co-7 only can be used for tagging.
