SUMMARY

An isogenic dry bean line (Phaseolus vulgaris) was developed using Rosinha 1454-10 as recurrent parent susceptible to Colletotrichum lindemuthiamun and Cornell 49-242 as the donor one. Ten backcrosses to the recurrent parent were made. Seedlings in the F₁ generation of each backcross and in the F₂ and F₃ of the 10^th backcross were inoculated using a spore suspension containing about 10⁵ spores/ml, through a De Vilbiss atomizer, under greenhouse or laboratory conditions.
The isogenic lines Rosinha 1454-10 and Rosinha 1454-10 Are Are will be used to estimate the losses of dry bean yield due to the anthracnose agent.
