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...
