Cultivars of common bean (Phaseolus vulgaris L.) capable of yielding well at low levels of native or added phosphorus (P) are highly desirable in many tropical production systems. The objective of the present study was to identify geographical regions which might be sources of such genotypes. A t...

Crosses were made and cv. and lines selected to combine the existing resistance to Xanthomonas campestris pv. phaseoli with adaptation to the tropics and to determine new sources of resistance. Crosses were made between adapted lines and sources of resistance, some with Great Northern genes. The ...

The Central American Adaptation Nursery (VIDAC 1988), comprising the best black- and red-seeded lines evaluated in the 1987 VIDAC, was established to identify well-adapted bean genotypes and obtain information on their degree of resistance to different crop problems. Outstanding (1) black-seeded ...
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 ...

Acid phosphatase is believed to be important for phosphorus scavenging and remobilization in plants, but its role in plant adaptation to low phosphorus availability has not been critically evaluated. To address this issue, we compared acid phosphatase activity (APA) in leaves of common bean (Phas...

El maíz y el fríjol son un componente vital de las dietas alimenticias de los humanos y la cultura en América Central. Más de un millón de familias de pequeños agricultores siembran estos cultivos para su subsistencia y producen el 70% del maíz y 100% del fríjol que se consume localmente. Sin emb...
