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 10th 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.
