Observations on the domestication of Phaseolus lunatus L
A total of 96 accessions (82 cultivated and 14 wild) of lima beans, Phaseolus lunatus, from CIAT`s collection, were analyzed for their seed`s CP composition. So far, 2 major families of electrophoretic patterns can be distinguished in the cultivated materials, showing that they come from 2 differ...

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...

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?
The lima bean, Phaseolus lunatus L., is a bean species with a broad distribution in the Americas that rivals that of common bean (P. vulgaris). In order to better understand the organization of genetic diversity and the pattern of domestication in lima bean, a review was conducted of the availabl...

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...
