Iron and zinc deficiencies are human health problems found throughout the world and biofortification is a plant breeding-based strategy to improve the staple crops that could address these dietary constraints. Common bean is an important legume crop with two major genepools that has been the focu...

Plant root development can be largely affected through the association of roots with plant growth-promoting rhizobacteria (PGPR). However, little is known about the identity of plant genes enabling such PGPR-plant root associations. Differences in the responsiveness to PGPR among cultivars sugges...

The study aimed to investigate the in vivo digestion of Phaseolus vulgaris phaseolin types differing in their subunit pattern composition. Diets contained either casein as the sole source of protein or a mixture (1:1) of casein and pure Sanilac (S), Tendergreen (T) or Inca (I) phaseolin either un...

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...

Advanced backcross QTL analysis was used to identify quantitative trait loci (QTL) for agronomic performance in a population of BC2F3:5 introgression lines created from the cross of a Colombian large red-seeded commercial cultivar, ICA Cerinza, and a wild common bean accession, G24404. A total of...

Host plant resistance in common bean (Phaseolus vulgaris L.) is a promising component in an integrated cropping system for managing thrips (Thrips palmi Karny) infestation. This study was conducted to identify quantitative trait loci (QTLs) for resistance to thrips in common bean, using F5:7 reco...

Low soil P availability is a primary constraint to common bean (Phaseolus vulgaris L.) production in Latin America and Africa. Substantial genotypic variation in bean adaptation to low phosphorus (LP) availability has been linked with root traits that enhance the efficiency of soil foraging. The ...

An estimated 60% of common bean (Phaseolus vulgaris L.) production worldwide is at risk of drought. A breeding program was developed at the International Center of Tropical Agriculture (CIAT) to create drought resistant breeding lines with varietal potential in the small red, small black, cream (...
