This project aims at: (1) identifying the major pathogens of the bean root rot complex, (2) screening for resistant germplasm, and (3) evaluating low-input control methods that will significantly decrease economic losses caused by root rots in the main bean producing regions of Peru, Ecuador, and...

El presente proyecto tiene por objetivos: 1) identificar los principales patogenos asociados con el complejo de pudriciones radicales del frijol; 2) seleccionar germoplasma resistente; y 3) evaluar metodos de control de bajo costo que permitan disminuir significativamente las perdidas economicas ...

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...

The bean weevil Acanthoscelides obtectus, is an important storage pest of common beans in Latin America and Africa. A few wild bean accessions from Mexico have been identified as highly resistant to the weevil. One accession, G 12952, was crossed to two susceptible bean cultivars differing in see...

El frijol (Phaseolus vulgaris L) es originario de América, reconociéndose dos centros de domesticación: Mesoamérica con cultivares de semilla pequeña y la región andina de América del Sur con cultivares de semilla grande. El frijol se cultiva ampliamente en el mundo en una gran diversidad de zona...
