Interest in bean genetic resources of Central America has resumed because of disease pressures (e.g., web blight, BGMV) and limitations of current bean varieties. As most of the diversity in landraces has been explored, focus is now on the exploration of wild forms of the primary gene pool and wi...


Araya Villalobos, RodolfoGonzález Ugalde, W.G.Camacho Chacon, FSánchez Trejos, Maria P.Debouck, Daniel G.[Observations on the geographic distribution, ecology and conservation status of several phaseolus bean species in Costa Rica]Observations on the geographic distribution, ecology and conservation status of several phaseolus bean species in Costa Rica

The wild common bean (Phaseolus vulgaris) is widely but discontinuously distributed from northern Mexico to northern Argentina on both sides of the Isthmus of Panama. Little is known on how the species has reached its current disjunct distribution. In this research, chloroplast DNA polymorphisms ...


Chacón Sánchez, María I.Pickersgill, BDebouck, Daniel G.Arias, J.S.[Phylogeographic analysis of the chloroplast DNA variation in wild common bean (Phaseolus vulgaris L.) in the Americas]Phylogeographic analysis of the chloroplast DNA variation in wild common bean (Phaseolus vulgaris L.) in the Americas

The genus Phaseolus includes important cultivated species as well as wild species with diverse ecological adaptations. Characterization of the ecological adaptations of the wild species would be useful for improved understanding, conservation, and utilization of these genetic resources. Salinity ...


Bayuelo Jiménez, Jeannette SofiaDebouck, Daniel G.Lynch, Jonathan P.[Salinity tolerance in Phaseolus species during early vegetative growth]Salinity tolerance in Phaseolus species during early vegetative growth

A collection trip of native Phaseolus germplasm was carried out over a 15-day period in the provinces of Jujuy, Salta, Tucuman, and Catamarca (Argentina) within the alt. range of 700-2200 m.a.s.l. Seeds of 26 wild populations of Phaseolus vulgaris var. aborigineus and of other species were collec...


Debouck, Daniel G.[Recoleccion de germoplasma nativo de Phaseolus]Recoleccion de germoplasma nativo de Phaseolus

Results are given from a Phaseolus germplasm field study carried out in Southern Nuevo Leon, Mexico: 143 samples of 8 different species. The presence of each one of the species in this part of the country is discussed. (CIAT)


Rodríguez C, M.Rodríguez T, S.Aguilar S., M.Debouck, Daniel G.[Phaseolus germplasm collection in Mexico]Phaseolus germplasm collection in Mexico

During a 3-wk. trip to western Guatemala to collect bean germplasm, 88 seed samples were collected, representing 10 species in different forms. The germplasm involves 3 cultivated species (coccineus, polyanthus, and vulgaris), the ancestral forms of coccineus, lunatus, and polyanthus, and 3 wild ...

A survey was carried out in Central Costa Rica in Jan. 1987, in an attempt to find web blight resistance in native var.; 43 samples representing 10 different taxa were found. Wild P. vulgaris was found in 2 different places in the province of San Jose; both populations presented truly wild charac...
