Significant advances in increasing tolerance to the leafhopper Empoasca kraemeri Ross & Moore in common bean have been obtained using a new breeding scheme where yield under leafhopper attack is the principal selection criterion in the evaluation of progenies. However, to further refine this bree...

Introducción y evaluación de germoplasma de habichuela arbustiva (Phaseolus vulgaris L.)
A survey of root-knot nematodes associated with bean (Phaseolus vulgaris) roots and soils in the major bean production regions of Colombia and Peru was conducted during 1988 1989. Over 150 samples were processed for these parasites, and specimens from more than 100 of the collections were identif...

La investigación se realizó en el CIAT, en la Granja de CIAT en Darién y fincas de agricultores del mismo municipio departamento del Valle, entre 1989 y 1991. El análisis de varianza para rendimiento de grano en las generaciones 2 y F6, mostró amplia interacción genotipo x ambiente. En general hu...

Evaluación de generaciones segregantes de fríjol Phaseolus vulgaris L. en campos de agricultores en contraste a la realizada en estación experimental
To satisfy farmer and consumer preferences, breeding efforts to increase yield potential in common bean must take into account the interrelated effects of growth habit, seed size, maturity, and gene pool on yield expression in segregating populations. To examine the relationships among these trai...
