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...

Observations on little-known Phaseolus germplasm of Ecuador
Mixtures of bean var. are cultivated in the Peruvian highlands in association with maize. Different wild types were found in abandoned fields in different areas. The presence of the wild types of P. vulgaris constitutes a basic generator of variability named the weed-crop complex. Field observati...

Presence of a wild-weed-crop complex in Phaseolus vulgaris L. in Peru?
Seventy nine samples of two Phaseolus species were collected during a germplasm exploration in Cusco. Of particular interest are: 25 landraces of P. vulgaris (of which 7 are popped beans) and 8 populations of a particular wild common bean. Strong indications about the existence of a crop-weed com...
