En el CIAT, Centro Experimental, Estación de Santander de Quilichao, (Cauca, Colombia) durante 1980 y 1981 se observó la presencia de marchitez en plantas de Zornia spp., asociada a Corynebacterium flaccumfaciens. En razón de ese registro y del riesgo que implicaba su presencia en uno de los siti...

En cinco muestras de semillas de B. dictyoneura cosechadas en la misma época en Colombia, Panamá y Costa Rica, se evaluó el efecto de tres niveles de calor seco (ambiente, 40 y 60°C) y tres tiempos de exposición (0, 72 y 240 h) aplicados a uno y tres meses poscosecha en espiguillas completas o es...

Cultivated common bean germplasm is especially diverse due to the parallel domestication of two genepools in the Mesoamerican and Andean centers of diversity and introgression between these gene pools. Classification into morphological races has helped to provide a framework for utilization of th...

A polyacrylamide gel electrophoresis procedure was developed for discriminating cultivars of the forage legume Pueraria phaseoloides on the basis of the patterns of cotyledon proteins. The genotypic marker proteins were extracted with 5M acetic acid and electrophoresed at pH 3.1 in aluminum lacta...

Phytate is an important antinutritional component of legume seeds, which chelates minerals that are essential to the human diet such as iron and zinc. Phytate levels are often correlated with total seed phosphorus (P). The objective of this research was to evaluate quantitative trait loci (QTL) f...

The food price crisis has led to assumptions that food price rises are due to inadequate food production, and that such food insecurity is linked to seed insecurity. Hence, in response to high food prices, seed resources worth hundreds of millions of US dollars are being shipped into vulnerable f...
