| description | A plant breeding program was developed, consisting of the following stages: (1) hybridization for disease resistance; (2) adaptation trial, and (3) screening for resistance. Several variations of Isariopsis griseola existing in Malawi as well as sources of resistance to this fungus were identified in local bean germplasm. Variation was observed in adaptation and disease resistance to angular leaf spot, common blight, BCMV, web blight, and rust. The highest yielding genotypes were also the most resistant: A 286 (508 kg/ha), A 344 (438), and BAT 477 (417). Pathogenic variation was observed for Isariopsis griseola (10 isolates) and sources of resistance to this pathogen were found. Bean genotypes PI 167399, Coco ala Creme, and G 05434 were resistant to all the isolates of the pathogen, the smallest lesions being observed in G 05434. (CIAT) |

(CIAT) Se desarrollo un programa de mejoramiento de frijol siguiendo 1) etapa de hibridizacion por resistencia a enfermedades; 2) ensayo de adaptacion y 3) seleccion por resistencia. Se identificaron algunas variaciones de Isariopsis griseola existentes en Malawi y fuentes de resistencia a este hongo en germoplasma de frijol local. Se encontro variacion en la adaptacion y resistencia a enfermedades (mancha foliar angular, anublo comun, BCMV, mustia hilachosa y roya). Los genotipos de mayor rendimiento tambien fueron los mas resistentes: A 286 (508 kg/ha), A 344 (438) y BAT 477 (417). Hubo variacion patogenica para Isariopsis griseola (10 aislamientos) y se demostro que existen fuentes de resistencia a este patogeno. Los genotipos de frijol PI 167399, Coco ala Creme y G 05434 fueron resistentes a todos los aislamientos del patogeno, presentando este ultimo las lesiones mas pequenas.
