Studies of diversity permit conclusions about the genetic structure of species. Systematically developed core collections are a particularly good tool for such purposes. The objective of this study was to evaluate the genetic structure between and within gene pools of a core collection of wild Ph...

We describe a method for applying geographical information systems (GIS) to exploring biodiversity in the wild relatives of crop species and illustrate its application to the wild common bean (Phaseolus vulgaris L.). We use the latitude, longitude and altitude of the location of origin of each ac...

Cassava is probably the most efficient producer of carbohydrate per unit land area under tropical conditions. The high productivity of cassava makes it an attractive source of renewable industrial raw material, provided ways are found to reduce production costs and solve constraints. Cassava has ...

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...

One hundred twenty five accessions of Passiflora (granadillas, parchitas, curubas, badea and passion fruits) belonging to 26 species of the genus were characterized using 50 RAPD markers. Furthermore 35 accessions belonging to 12 species were analyzed by RFLPs of chloroplast DNA. RAPDs markers sh...
