Cichy, Karen AnnCaldas, GVSnapp, Sieglinde S.Blair, Matthew W.[QTL analysis of seed iron, zinc, and phosphorus levels in an Andean bean population]QTL analysis of seed iron, zinc, and phosphorus levels in an Andean bean population

Cassava (Manihot esculenta Crantz) is a major root crop widely grown in the tropics. Cassava bacterial blight, caused by Xanthomonas axonopodis pv. manihotis (Xam), is an important disease in Latin America and Africa resulting in significant losses. The preferred control method is the use of resi...

Hoyos Villegas, ValerioSong, QijianWright, Evan M.Beebe, Stephen E.Kelly, James D.[Joint linkage QTL mapping for yield and agronomic traits in a composite map of three common bean RIL populations]Joint linkage QTL mapping for yield and agronomic traits in a composite map of three common bean RIL populations

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...


Blair, Matthew W.Medina, JIAstudillo, CarolinaRengifo Medina, JBeebe, Stephen E.Machado, GGraham, RD[QTL for seed iron and zinc concentration and content in a Mesoamerican common bean (Phaseolus vulgaris L.) population]QTL for seed iron and zinc concentration and content in a Mesoamerican common bean (Phaseolus vulgaris L.) population

We evaluated cassava bacterial blight (CBB) infection in an pair-cross population of 150 individuals derived from an intra-specific cross between two non-inbred cassava (Manihot esculenta Crantz) lines. The replicated trials were carried out in the field under high disease pressure over two conse...


Jorge, VFregene, Martin A.Velez, C.M.Duque E., Myriam CristinaTohme, Joseph M.Verdier, Valérie[QTL analysis of field resistance to Xanthomonas axonopodis pv. manihotis in cassava]QTL analysis of field resistance to Xanthomonas axonopodis pv. manihotis in cassava

Aluminum (Al) toxicity is a major limiting factor of crop production in acid soils, which are found mostly in developing countries of the tropics and sub-tropics. Common bean (Phaseolus vulgaris L.) is particularly sensitive to Al toxicity; and development of genotypes with better root growth in ...


López Marin, H.D.Rao, Idupulapati M.Blair, Matthew W.[Quantitative trait loci for root morphology traits under aluminum stress in common bean (Phaseolus vulgaris L.)]Quantitative trait loci for root morphology traits under aluminum stress in common bean (Phaseolus vulgaris L.)

Low phosphorus availability is a primary constraint to crop production in developing countries. Adventitious roots play an important role in phosphorus acquisition, as they are localized near the soil surface where phosphorus is relatively abundant. A population of recombinant inbred lines of Pha...


Ochoa, IEBlair, Matthew W.Lynch, Jonathan P.[QTL analysis of adventitious root formation in common bean under contrasting phosphorus availability]QTL analysis of adventitious root formation in common bean under contrasting phosphorus availability

Genetic mapping of early bulking in a full-sib population of cassava was continued in a selfed family of 268 cassava plants derived from a single progeny of the full-sib population. The pseudo F2 population was analysed with 122 segregating SSR markers. A previously constructed linkage map of cas...

Chavarro, CBlair, Matthew W.[QTL analysis and effect of the fin locus on tropical adaptation in an inter-gene pool Common Bean population]QTL analysis and effect of the fin locus on tropical adaptation in an inter-gene pool Common Bean population

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...
