Reactions of 12 differential cultivars to 60 isolates of Colletotrichum lindemuthianum confirmed the presence of the gamma race in Asturias (North of Spain). In addition, one new race was identified as delta-mutant. The new binary nomenclature system identify the gamma race as race 38 and the delta-mutant race as race 7. A total of 40 germplasm lines which included 32 CIAT bean accessions and 8local bean varieties were evaluated for anthracnose resistance. Vegetative and reproductive adaptation of bean accessions was studied, as well as characterization for the presence of genes controlling expression of dwarfing. Results obtained reveal that14 bean genotypes showed good general adaptation and uniform resistance to anthracnose. Four bean lines resistant to anthracnose are carriers of DL genes. Resistant sources selected are quite diverse for plant type, seed color and seed size.
