Some historical aspects and 2 possible reasons for the domestication of Phaseolus vulgaris and P. lunatus are considered, namely, that (1) bean domestication occurred at least 8000 yr ago in the southern Peruvian Andes, as a food plant, or that (2) beans were domesticated for different reasons an...

No wild Phaseolus bean germplasm is currently available from seed banks for Ecuador. Because of the decisive importance of the wild forms in evolutionary studies of the bean crops, and given the key geographical situation of that country in the northern Andes, a joint exploration was recently car...

Background Common bean (Phaseolus vulgaris) is an important grain legume and there has been a recent resurgence in interest in its relative, tepary bean (P. acutifolius), owing to this species’ ability to better withstand abiotic stresses. Genomic resources are scarce for this minor crop species ...

Background: The wild relatives of crops represent a major source of valuable traits for crop improvement. These resources are threatened by habitat destruction, land use changes, and other factors, requiring their urgent collection and long-term availability for research and breeding from ex situ...

The genetic variable of seven Phaseolus taxa has been evaluated on the basis of molecular data and the results have used to clarify the phyletic relationships between several taxa of the P. coccineus L. complex. Chloroplast DNA (cpDNA) from 33 populations was digested with six restriction endonuc...
