Descrição: dc.descriptionThe aim of the study was to verify whether a mixture of lines containing equal amounts of seven lines of Carioca‐type common bean, all agronomically uniform but each presenting different patterns of resistance to Colletotrichum lindemuthianum, would be less damaged by anthracnose than the individual pure lines. Plants cultured in experimental plots in Lavras, Minas Gerais, Brazil, in the dry harvest seasons of 2007 and 2008 were inoculated with a mixture of races 65, 81, 87, 89 and 337 of the pathogen, and the severity of anthracnose was evaluated at 10‐ day intervals commencing 12 days after inoculation. The progress of the disease was estimated from the coefficients of the linear regression equations (b1) and from the areas under the disease progress curves (AUDPC). The mean grain yields were determined in both experimental periods. The value of b1 for the multiline was not different from that presented by the resistant line MA‐II‐22 and indicated a slower progress of the disease over time compared with susceptible lines. There were no differences in AUDPC values between the multiline and the resistant lines. The multiline presented a grain yield that was similar to those of the most productive lines even though susceptible lines comprised more than 28% of the mixture and such lines showed the lowest yields of grain. It is concluded that the use of the mixture of lines represents a good strategy for reducing the progress of anthracnose in the field and, as a consequence, reducing loss of grain yield.-
