| description | The Bean Team Nursery (VEF) is the 1st uniform and multidisciplinary evaluation for adaptation and disease and insect resistance and is composed of advanced, coded CIAT hybrid lines from various breeding projects, the germplasm bank, and national programs. Among the bush bean entries, 16 percent showed resistant reactions to rust (Uromyces phaseoli) and 20 percent were intermediate. Entries resistant and intermediate to anthracnose (Colletotrichum lindemuthianum) were 34 and 24 percent, resp. The frequency of lines combining important traits also increased in the 1980 VEF. For example, 103 entries combine resistance to BCMV and anthracnose with non-black grain color, factors necessary for acceptability in Africa. Preliminary yield trials (EP) consisted of 105 lines (91 bush and 14 climbing) selected from 594 evaluated in the 1979 VEF. All EP materials were resistant to the Florida and NY 15 strains of BCMV. Also, 68 materials, out of the 105 evaluated, possessed resistance to 3 or more diseases or insect pests. Tables are included with the results obtained in climbing bean and bush bean yield trials at CIAT-Palmira and CIAT-Popayan. (Extract) |

(Extract) La primera evaluacion multidisciplinaria y uniforme que se hacede los materiales por su adaptacion y resistencia a enfermedades yplagas es en el vivero del equipo de frijol (VEF) el cual secompone de lineas hibridas avanzadas, codificadas por el CIAT,procedentes de varios proyectos de mejoramiento, del banco degermoplasma y de los programas nacionales. El 16 por ciento de losmateriales de frijol arbustivo presento reacciones de resistenciaa roya (Uromyces phaseoli) y el 20 por ciento mostro resistenciaintermedia. Hubo un 34 por ciento de materiales con resistencia aantracnosis (Colletotrichum lindemuthianum) y un 24 por ciento conresistencia intermedia. La frecuencia de lineas que combinancaracteres importantes tambien aumento en el VEF de 1980; porejemplo, 103 materiales combinan resistencia a BCMV y a antracnosiscon colores de grano diferentes al negro, factores necesarios parasu aceptabilidad en Africa. Los ensayos preliminares de rendimiento(EP) abarcaron 105 lineas (91 arbustivas y 14 volubles)seleccionadas a partir de las 594 evaluadas en el VEF de 1979.Todos los materiales del EP fueron resistentes a las cepas Floriday NY 15 de BCMV; ademas, un total de 68 materiales, de los 105evaluados, tenian resistencia a 3 o mas enfermedades e insectosplaga. Se incluyen tablas con los resultados obtenidos en losensayos de rendimiento de frijol voluble y arbustivo en lasestaciones del CIAT en Palmira y Popayan.
