Se cuantificó la variabilidad genética de una muestra de 116 accesiones de habichuela P. vulgaris, cultivadas en centros primarios y secundarios de domesticación. Se evaluaron 18 descriptores morfo-agronómicos asociados con características de la planta, vaina y semilla. Mediante el análisis de la...

Thirteen male sterile plants were identified in a yield trial of bean germplasm accession G08063 grown at CIAT-Palmira in 1977. Line G08063 is indeterminate, type III with postrate growth; it is relatively early and produces small white seeds. A fertility score (less than 1.3 sterile, 1.3-2.5 par...

A brief reference is made to new bean germplasm accessions and breeding lines identified at CIAT with specific architectural traits. Examples are given for type I bush beans with 10 or more nodes on the main stem, erect branching, suppressed branching, short foliage and internodes, lanceolate lea...

A selection study was conducted with 6 hybrid bean populations in 3 double groups, with low, intermediate, and high yield potential, at CIAT`s exptl. farm in Popayan (Cauca, Colombia), in a P-deficient soil with pH 4.5. These soil conditions allow for high disease incidence such as anthracnose (C...

Knowledge of patterns of genetic diversity enhances the efficiency of germplasm conservation and improvement. This study examined the organization of diversity for morphological and agronomic characteristics in 306 landraces of cultivated common bean (Phaseolus vulgaris L.) from Latin America and...
