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...

Seed increase of the 1300 accessions from both the cultivated subspecies (coccineus and polyanthus) and the wild forms of Phaseolus coccineus is being carried out at 2 locations of Colombia. In Popayan (1700 m alt., 18 degrees Celsius mean temp., and 2000 mm annual rainfall), 12 plants of each ac...

The origin of 5 Phaseolus species cultivated in America (P. vulgaris, P. lunatus, P. coccineus, P. acutifolius, and P. polyanthus) is discussed within the context of a broader theory of the origin of this genus, for which 3 centers of origin may be defined: Mesoamerica, the northern and southern ...

Primary diversification of Phaseolus in the Americas: Three centres?
Different aspects on the history, screening, and domestication effect on the evolution of the bean species are discussed, based on the concept of species domestication. Data are examined on plant systematics and geography, etnological botany, biochemistry, arqueology, and genetics of the crop. Th...

A five days collecting expedition was carried out through the Departments of Cundinamarca and Boyaca (Colombia), corresponding to the dry subtropical forest of the Andean Zone (1500-2000 m.a.s.l.). The germplasm collected includes 40 samples of beans of the genus Phaseolus, 1 sample of Vigna sp, ...
