Tohme, Joseph M.Beebe, Stephen E.Iwanaga, Masaru[The combined use of agroecological and characterisation data to establish the CIAT Phaseolus vulgaris core collection]The combined use of agroecological and characterisation data to establish the CIAT Phaseolus vulgaris core collection

Important aspects involved in the establishment of a breeding program are indicated. The 1st step is to identify production constraints in order to define priorities. Solutions proposed should emphasize the improvement of materials or the adaptation and innovation of agronomic practices; this str...

Se indican algunos aspectos de importancia en el establecimiento de un programa de fitomejoramiento, donde el primer paso es identificar las limitaciones a la productividad en un orden que permita definir prioridades. Asi, se implementan las soluciones enfatizando el mejoramiento de materiales o ...


Beebe, Stephen E.[La definicion del problema, el objetivo del programa de mejoramiento y planificacion del programa: aspectos claves y errores comunes]La definicion del problema, el objetivo del programa de mejoramiento y planificacion del programa: aspectos claves y errores comunes

This nursery was organized in response to the need for improving adaptation and obtaining genetic information on the resistance or reaction to the different stress environments (biotic and abiotic) to which beans are subjected in production areas. Results are given for the best black- and red-see...

Este vivero se organizo con base en la necesidad de conseguir una mejor adaptacion e informacion genetica sobre la resistencia o la reaccion a los diferentes ambientes de estres (bioticos o abioticos) a los cuales se somete el frijol en las areas de produccion. Se presentan los resultados de las ...


Orozco S., S.H.Beebe, Stephen E.Dessert, J.M.[Informe del vivero de adaptacion centroamericano VIDAC 1987]Informe del vivero de adaptacion centroamericano VIDAC 1987

To select a plant genotype that will thrive in targeted environments it is critical to understand the genotype by environment interaction (GEI). In this study, multi-environment QTL analysis was used to characterize node addition rate (NAR, node day− 1) on the main stem of the common bean (Phaseo...

Common bean (Phaseolus vulgaris L.) is the most important food legume in the diet of poor people in the tropics. Drought causes severe yield loss in this crop. Identification of traits associated with drought resistance contributes to improving the process of generating bean genotypes adapted to ...


Polanía Perdomo, José A.Poschenrieder, CharlotteBeebe, Stephen E.Rao, Idupulapati M.[Effective use of water and increased dry matter partitioned to grain contribute to yield of common bean improved for drought resistance]Effective use of water and increased dry matter partitioned to grain contribute to yield of common bean improved for drought resistance

Common bean productivity is reduced by several abiotic stress factors like drought and low soil fertility, leading to yield losses particularly in low input smallholder farming systems in the tropics. To understand the genetics of stress tolerance, and to improve adaptation of common bean to adv...

Rao, Idupulapati M.Beebe, Stephen E.Polanía Perdomo, José A.Grajales, Miguel A.Cajiao V., César HernandoRicaurte Oyola, José Jaumer[Evidence for genotypic differences among elite lines of common bean in the ability to remobilize photosynthate to increase yield under drought]Evidence for genotypic differences among elite lines of common bean in the ability to remobilize photosynthate to increase yield under drought

The common bean is a tropical facultative short day legume that is now grown in tropical and temperate zones. This observation underscores how domestication and modern breeding can change the adaptive phenology of a species. A key adaptive trait is the optimal timing of the transition from the ve...
