Islam, F.M.A.Basford, KERedden, RJBeebe, Stephen E.[Preliminary evaluation of the common bean core collection at CIAT]Preliminary evaluation of the common bean core collection at CIAT

Common beans (Phaseolus vulgaris L) contain a number of antinutritional factors such as condensed tannins. Reducing tannin concentration might contribute to improving the nutritional quality of common bean. But polyphenolics are involved in resistance to diseases and pests, and reducing tannin co...


Islam, F.M.A.Rengifo, JRedden, RJBasford, KEBeebe, Stephen E.[Association between seed coat polyphenolics (tannins) and disease resistance in common bean]Association between seed coat polyphenolics (tannins) and disease resistance in common bean

Legumes provide essential micronutrients that are found only in low amounts in the cereals or root crops. An ongoing project at CIAT has shown that the legume common bean is variable in the amount of seed minerals (iron, zinc, and other elements), vitamins, and sulfur amino acids that they contai...


Blair, Matthew W.Astudillo, CarolinaRengifo, JBeebe, Stephen E.Graham, R[QTL analyses for seed iron and zinc concentrations in an intra-genepool population of Andean common beans (Phaseolus vulgaris L.)]QTL analyses for seed iron and zinc concentrations in an intra-genepool population of Andean common beans (Phaseolus vulgaris L.)

During germplasm explorations carried out in Peru and Colombia, interbreeding complexes of wild and cultivated common bean were observed in both countries, eight in Apurimac and Cusco departments of Peru and eight in Cundinamarca and Boyacá departments of Colombia. The existence of complexes was ...


Beebe, Stephen E.Toro Chica, OrlandoGonzález, Alma VivianaChacón Sánchez, María I.Debouck, Daniel G.[Wild-weed-crop complexes of common bean (Phaseolus vulgaris L., Fabaceae) in the Andes of Peru and Colombia, and their implications for conservation and breeding]Wild-weed-crop complexes of common bean (Phaseolus vulgaris L., Fabaceae) in the Andes of Peru and Colombia, and their implications for conservation and breeding

Micronutrients are essential elements needed in small amounts for adequate human nutrition and include the elements iron and zinc. Both of these minerals are essential to human well-being and an adequate supply of iron and zinc help to prevent iron deficiency anemia and zinc deficiency, two preva...


Blair, Matthew W.Astudillo, CarolinaGrusak, M.A.Graham, RBeebe, Stephen E.[Inheritance of seed iron and zinc concentrations in common bean (Phaseolus vulgaris L.)]Inheritance of seed iron and zinc concentrations in common bean (Phaseolus vulgaris L.)

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...


Blair, Matthew W.Sandoval Medina, TACaldas, GVBeebe, Stephen E.Paez, MI[Quantitative trait locus analysis of seed phosphorus and seed phytate content in a recombinant inbred line population of common bean]Quantitative trait locus analysis of seed phosphorus and seed phytate content in a recombinant inbred line population of common bean
