The 3-stage progeny evaluation program at CIAT tested 1902 materials (67.4 percent new entries) in 1986, distributed as follows: 1st stage (bean evaluation nursery-VEF), 1282 entries; 2nd stage (preliminary trials-EP), 435 entries; and 3rd stage (IBYAN), 185 entries. The following data are includ...

El programa de evaluacion de progenies en 3 etapas en CIAT probo en 1986 un total de 1902 materiales (67.4 por ciento nuevas entradas), distribuidos como sigue: primera etapa (vivero de evaluacion de frijol-VEF), 1282 entradas; segunda etapa (ensayos preliminares-EP), 435 entradas; y tercera etap...

During 1986 screening of advanced bean lines for efficiency at low levels of P and for tolerance to high levels of Al saturation continued. A review of data from 8 yr. of screening indicated that the genetic variability of beans for these 2 characteristics is low. Furthermore, the data suggest th...

La seleccion de lineas avanzadas de frijol por eficiencia a bajos niveles de P y tolerancia a altos niveles de saturacion de Al continuo durante 1986. Una revision de datos de 8 anos de seleccion indico que la variabilidad genetica de frijol para estas 2 caracteristicas es baja. Ademas, los datos...

In 1986 the project in Peru concentrated on 3 main activities: genetic improvement, seed production, and scientific training. The most significant advances in the coastal region consisted of the introduction of 35 advanced Canario type, BCMV-resistant bean lines. These lines were also evaluated i...

En 1986 el proyecto en Peru se concentro en 3 actividades principales: mejoramiento genetico, produccion de semilla y capacitacion cientifica. Los avances mas significativos en la region costera consistieron en la introduccion de 35 lineas avanzadas de frijol tipo Canario, resistentes a BCMV. Est...

In 1986 the bean program for Central America and the Caribbean, including tropical Mexico and Panama, continued with the transfer of technology generated by the national programs to the farmers, through efficient on-farm research. An efficient network of information and material on beans was form...

En 1986 el programa de frijol para America Central y el Caribe, incluyendo Mexico tropical y Panama, continuo con la transferencia de tecnologia generada por los programas nacionales a los agricultores, a traves de una eficiente investigacion a nivel de finca. Se formo una red eficiente de inform...

Close collaboration between CIAT and Brazil continued during 1986. Germplasm development was conducted through evaluating the jointly developed crosses in Brazil, rather than selecting the fixed lines in CIAT prior to shipment to Brazil. By the end of 1986, those segregating populations were in t...

La colaboracion estrecha entre CIAT y Brasil continuo durante 1986. Se realizo desarrollo de germoplasma a traves de la evaluacion de los cruzamientos desarrollados conjuntamente en Brasil, en lugar de seleccionar las lineas fijas en CIAT antes de su envio al Brasil. Hacia finales de 1986, estas ...

Aspects of a bean project proposal in Malawi are discussed as follows: objectives, review of bean research and production, government strategies, assistance from international institutions, institutional framework for bean industry, project justification (seed multiplication and distribution; cro...

Se tratan los siguientes aspectos de un proyecto de frijol propuesto en Malawi: objetivos, revision de la investigacion y la produccion de frijol, estrategias gubernamentales, ayudas de instituciones internacionales, marco institucional para la industria frijolera, justificacion (multiplicacion y...

On-farm research activities in 1986 continued in the areas of training, network establishment, methodology adaptation, technology development on-farm, and technology adaptation to specific areas. One early result is a better understanding of the variability in the adaptation of the newly adopted ...

Las actividades de investigacion en fincas en 1986 continuaron en las areas de capacitacion, establecimiento de redes, adaptacion de metodologias, desarrollo de tecnologias a nivel de finca y adaptacion de tecnologias a areas especificas. Un primer resultado constituye un mejor entendimiento de l...

The Great Lakes Regional Bean Program works with the agricultural research institutions of Burundi, Rwanda, and Zaire. Advanced breeding lines were introduced as potential new var. for the region and/or as sources of resistance to angular leaf spot, anthracnose, Ascochyta leaf spot, halo and BCMV...

Economics research in the bean program continues to concentrate on production studies, marketing issues, policy analysis, and training. Diagnostic studies of current production systems and problems were conducted in Brazil, Colombia, Costa Rica, Dominican Republic, El Salvador, Nicaragua, and Per...

La investigacion sobre aspectos economicos en el programa de frijol sigue concentrandose en estudios de produccion, mercadeo, analisis de politicas y capacitacion. Se llevaron a cabo estudios sobre el diagnostico de los actuales sistemas y problemas de produccion en Brasil, Colombia, Costa Rica, ...

The Southern Africa Development Coordination Conference (SADCC) region covers Tanzania, Malawi, Zambia, Zimbabwe, Mozambique, Angola, Botswana, Lesotho, and Swaziland, and is the largest of the 3 regions hosting a CIAT bean program in Africa. Bean production from the SADCC region amounts to about...

La region de Southern Africa Development Coordination Conference (SADCC) comprende a Tanzania, Malawi, Zambia, Zimbabwe, Mozambique, Angola, Botswana, Lesotho y Swazilandia, y es la region mas grande de las 3 que tienen un programa de frijol de CIAT en Africa. La produccion de frijol de la region...
