Resumo: All nineteen Colletotrichum isolates causing anthracnose in lupin plants growing in southern Chile belong to Colletotrichum lupini, confirming an absence of interspecific variation in the causal agent of anthracnose. Nevertheless, intraspecific genetic diversity was detected with random amplified polymorphic DNA (RAPD) markers. Based on a multiloci analysis, 14 molecular phenotypes were described among the local C. lupini isolates. The largest genetic distance between two isolates was 0.57. The analyzed isolates showed clear differences in virulence on susceptible cultivar 'Kiev Mutant' with disease severity ranging from 15 to 75% of seedlings. The high degree of DNA polymorphism, the large number of different molecular phenotypes, and the variation in virulence suggest the existence of different strains. Study of strain virulence and diversity may aid in the development of more efficient genetic improvement programs for anthracnose tolerance.
