Deficiencies of vitamin A, iron, and zinc affect over one-half of the world's population. Progress has been made to control micronutrient deficiencies through supplementation and food fortification, but new approaches are needed, especially to reach the rural poor. Biofortification (enriching the...

En Colombia las variedades de arroz desarrolladas se consideran como resistentes a Tagosodes orizicolus. Dada la estrechez genética de las fuentes de resistencia, se inició este estudio para identificar los progenitores donantes de resistencia usados con mayor frecuencia en América Latina. Los ma...

Resistance to insects in cow peas was studied in a diallel cross and in a test cross. Number of pods and seed yield under unsprayed conditions, expressed as a percentage of their values under sprayed conditions, were confirmed as reliable characters for the assessment of resistance and as suitabl...

Nutritionally enhanced beans (NEB) with more Fe and Zn than conventional beans (CB) and nutritionally enhanced maize (NEM) with more tryptophan and lysine than conventional maize (CM) were developed as part of a crop-biofortification strategy to improve human nutrition. Proxy measures were used t...

The effectiveness of supplementing local bean (Phaseolus vulgaris) mixtures with varieties resistant to angular leaf spot, caused by Phaeoisariopsis griseola, was evaluated in the Great Lakes region of Africa. The severity of angular leaf spot was lower (P = 0.05) in farmer mixtures supplemented ...

Native populations of Stylosanthes capitata, a promising perennial pasture legume in tropical America, were evaluated for their reaction to a virulent widespread race of Colletotrichum gloeosporioides. Considerable variation in anthracnose reaction among progenies from individual plants, among pl...

Los recientes cambios en los sistemas de producción de maíz (Zea mays L.), incluyendo siembras escalonadas y continúas del cultivo en Colombia, han incrementado la incidencia de algunas enfermedades, entre las que se destaca el mosaico de la caña de azúcar (SCMV). Estudios de varios investigadore...
