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...

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...

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...
