The main activities of bean virology at CIAT in 1984 involved screening for BCMV dominant resistance (selection of homozygous BCMV resistant lines), BCMV multiple gene resistance, BCMV recessive gene immunity, and the management and prognosis of other important viral diseases of beans involving t...

Las principales actividades sobre virologia de frijol en CIAT durante 1984 incluyeron seleccion por resistencia dominante al BCMV (seleccion de lineas homocigotas resistentes), por resistencia multiple de genes al BCMV, por inmunidad al gen recesivo de BCMV y el manejo y pronostico de otras enfer...

Scientific training at CIAT continues to support the efforts of researchers particularly with respect to the training of technicians in the evaluation of promising germplasm. For training outside CIAT headquarters, greater emphasis was given to the study of limiting bean production factors at the...

La capacitacion cientifica en CIAT continua apoyando los esfuerzos de los investigadores, particularmente en relacion con la capacitacion de tecnicos para la evaluacion de germoplasma promisorio. En la capacitacion en sedes fuera de CIAT, el mayor enfasis se dio al estudio de los factores limitan...

Research work carried out by CIAT in 1980 and results obtained are briefly analyzed: acquisition, evaluation, and distribution of germplasm; bush and climbing bean improvement; resistance to viral (BCMV, BYMV, soybean mosaic virus, bean chlorotic mottle virus, and BGMV), fungal (rust, anthracnose...

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 ...

Research carried out by CIAT on specific character improvement is described and the results obtained in the following studies are given: resistance to viral (BCMV, combined BCMV and BYMV, bean chlorotic mottle virus, and BGMV), fungal (anthracnose, angular leaf spot, rust, and web blight), and ba...

Se describen las investigaciones realizadas por CIAT sobre mejoramiento del caracter especifico y se presentan los resultados obtenidos sobre: resistencia a enfermedades virales (BCMV, combinacion de BCMV y BYMV, virus del moteado clorotico del frijol y BGMV), fungicas (antracnosis, mancha foliar...

Research activities carried out by CIAT in collaboration with national research institutions for the improvement of bean production in the Central American and Caribbean region are analyzed. In 1981, preliminary trials (EP) were planted in Costa Rica and Guatemala in an effort to identify promisi...

Research on plant pathology carried out during 1981 emphasized the study of some epidemiological, etiological, and physiological factors related to the occurrence of the superelongation disease of cassava caused by Sphaceloma manihoticola. Dry-heat treatments (60 degrees Celsius for 14 days) brea...
