Evidence for genetic diversity in cultivated common bean (Phaseolus vulgaris) is reviewed. Multivariate statistical analysis of morphological, agronomic, and molecular data, as well as other available information on Latin American landraces representing various geographical and ecological regions...


Singh, S.P.Gepts, Paul L.Debouck, Daniel G.[Races of common bean (Phaseolus vulgaris, Fabaceae)]Races of common bean (Phaseolus vulgaris, Fabaceae)

Total seed protein variability in a sample of 163 entries of year-bean (Phaseolus polyanthus), including wild, feral and cultivated forms of the whole range of distribution in Latin America was studied using 1-dimensional SDS/PAGE and 2-dimensional IEF-SDS/PAGE. Ten different patterns were observ...


Schmit, VéroniqueDebouck, Daniel G.[Observations on the origin of Phaseolus polyanthus Greenman]Observations on the origin of Phaseolus polyanthus Greenman

The taxonomic classification of the wild Lima bean complex needs to be assessed to select species for use in breeding programs and to identify genetic resources for conservation. The objectives of this study were to determine the genetic relationships among, and the phylogeny of, wild Lima bean (...


Caicedo, ALGaitán Solís, ElianaDuque E., Myriam CristinaToro Chica, OrlandoDebouck, Daniel G.Tohme, Joseph M.[AFLP fingerprinting of Phaseolus lunatus L. and related wild species from South America]AFLP fingerprinting of Phaseolus lunatus L. and related wild species from South America

Crop wild relatives that have experienced multiple and independent domestication events provide an excellent model for understanding adaptation processes in crop populations and a first and relevant aspect to investigate is the geographic origin of landraces. The aim of this research was to estab...

Chloroplast DNA (cpDNA) diversity has been examined using PCR-RFLP and RFLP strategies for phylogenetic studies in the genus Phaseolus. Twenty-two species, including 4 of the 5 cultivated species (P. lunatus L., the Lima bean; P. vulgaris L., the common bean; P. coccineus L., the runner bean and ...

Wild common bean in the Central Valley of Costa Rica: ecological distribution and molecular characterization. This work offers an update on the distribution of wild common bean in Costa Rica. its ecology and molecular characterization. To date 22 populations have been discovered in four watershed...
