| Resumo: |
The cultivars, AB 136 and G 2333 both resistant to Colletotrichum lindemuthianum races 69 and 453, were crossed with the cultivars Michelite and Perry Marrow (susceptible to both races), with Dark Red Kidney and Cornell 49242 (resistant to both races) and F1 and F2 generations were obtained. Plants were inoculated using a spore suspension at 1.2 x 10(6) concentration. The reaction of F1 and F2 populations showed that Dark Red Kidney, Cornell 49242 and AB 136 cultivars had the dominant genes A (Co-1), Are (Co-2) and Co-6, respectively, was conferring resistance to races 69 and 453. The segregation data obtained from F2 populations indicated that G 2333 carried two dominant resistance genes Co-5 gene and another one Co-7 for 69 and 453 races. The dominant genes in G 2333 and its resistance to C. lindemuthianum race could be transferred to provide anthracnose resistance to susceptible cultivars relatively easy.
