Primary emphasis is being placed on a search for genotypes with erect architecture adapted to narrow row spacings and high populations and which show marked yield increases under intensive agronomic management. This research strategy is complemented by studies on specific problems such as exploit...

Se ha dado enfasis fundamental a la busqueda de genotipos con arquitectura erecta, adaptados a espacios estrechos entre hileras y altas poblaciones y que muestren incrementos notables en rendimiento bajo manejo agronomico intensivo. Esta estrategia de investigacion se complementa con estudios sob...

Snap bean improvement at CIAT has been carried out collaboratively with Washington State U. since 1983, to incorporate disease resistance and tropical adaptation from the dry bean improvement programs into green beans. An international adaptation nursery of advanced snap bean lines was distribute...

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 emphasis was given to testing promising bean germplasm for yields and the 1st materials bred at CIAT specifically for drought tolerance. Preliminary screening was performed under mild stress in the 1st semester, while exceptionally dry weather permitted evaluation under high levels of...

Durante 1986 se dio enfasis a pruebas de germoplasma promisorio de frijol por rendimiento y de los primeros materiales mejorados en CIAT especificamente por tolerancia a la sequia. La seleccion preliminar se efectuo en condiciones de estres leve en el primer semestre, en tanto que condiciones de ...

El mejoramiento de habichuela en CIAT se ha realizado en colaboracion con la U. del estado de Washington desde 1983, para incorporar la resistencia a enfermedades y la adaptacion tropical de los programas de mejoramiento de frijol a la habichuela. Se distribuyo un vivero internacional de adaptaci...

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 ...

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...

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...

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...
