    Abstract/Description
    Diversidad de razas de Colletotrichum lindemuthianum en Antioquía y evaluación de germoplasma de frijol crema-rojo por resistencia a antracnosis. Para verificar si la composición de razas en el Oriente de Antioquía se caracterizaron 15 aislamientos de C. lindemuthianum, usando 12 variedades diferenciales de frijol aceptadas internacionalmente. Se identificaron 11 razas, seis de las cuales (9, 131, 135, 139, 643, y 645) fueron caracterizadas por primera vez. Además, se evaluaron 49 genotipos procedentes de los bancos de germoplasma del CIAT y CORPOICA y cultivares de agricultor de municipios productores. Los genotipos fueron evaluados en campo y en invernadero con las razas más virulentas del patógeno (651 y 653) encontradas en Antioquía. Sólo cuatro genotipos (AND1084, SUG130, LAS106 y DiacolCatio) mostraron resistencia a ambas razas. Estos genotipos podrían usarse como parentales para un plan de cruzas, con el fin de introducir genes de resistencia a variedades de importancia comercial que presenten susceptibilidad a la antracnosis. = Diversity of Colletotrichum lindemuthianum races in Antioquia and evaluation of cream-red bean germplasm for anthracnose resistance. To verify the composition of Colletotrichum lindemuthianum races in east of Antioquia, 12 differential bean varieties were used to characterize 15 isolates collected from naturally infected bean varieties. Eleven races were identified among the 15 isolates characterized, six of which (races 9, 131, 135, 139, 643, y 645) were characterized for the first time. In addition, we evaluated 49 bean genotypes collected from the bean genebank of CIAT and CORPOICA, as well as landraces from farmers in producing. These genotypes were evaluated under natural field conditions as well as in the greenhouse, using races 651 and 653, previously identified as the most virulent races from Antioquia. Only four genotypes (AND1084, SUG130, LAS106 and Diacol Catio) were resistant under both field and greenhouse conditions. These genotypes can be used as parents in breeding programs to introduce anthracnose resistant genes to bean genotypes with commercial seed types.
