Chacón Sánchez, María I.Pickersgill, BDebouck, Daniel G.[The common bean has been part of the Great American Biotic Interchange : Evidence from the study of cpDNA and implications for conservation and breeding]The common bean has been part of the Great American Biotic Interchange : Evidence from the study of cpDNA and implications for conservation and breeding

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

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

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...


Debouck, Daniel G.Araya Villalobos, RodolfoOcampo S., R.A.González Ugalde, W.G.[Collecting Phaseolus in Costa Rica]Collecting Phaseolus in Costa Rica

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 ...

Freyre, RosannaRíos E., RaúlGuzmán, LorenaDebouck, Daniel G.Gepts, Paul L.[Ecogeographic distribution of Phaseolus spp. (Fabaceae) in Bolivia]Ecogeographic distribution of Phaseolus spp. (Fabaceae) in Bolivia

During a review of Phaseolus under-taken by the senior author to clarify the variability of the P. coccineus L. species complex, a few herbarium specimens of what appeared to be a new species from Costa Rica and Panama were encountered. Subsequent field collecting by the junior author confirmed t...
