Common bean (Phaseolus vulgaris L.) has evolved rapidly in Africa and is steadily transforming from a traditional subsistence to a market-oriented crop, with major impacts on household incomes, food and nutritional security, and national economies. However, these benefits are yet to be felt in ma...

The genetic variable of seven Phaseolus taxa has been evaluated on the basis of molecular data and the results have used to clarify the phyletic relationships between several taxa of the P. coccineus L. complex. Chloroplast DNA (cpDNA) from 33 populations was digested with six restriction endonuc...

The wild, red-flowered Phaseolus glabellus is generally considered either as a species of the P. coccineus complex or as a subspecies of P. coccineus. Biogeographic considerations as well as experimental hybridization, seed storage protein electrophoresis and cpDNA polymorphism point at its isola...

During a review of Phaseolus under-taken by the senior author to clarify the variability of the P. coccineus L. species complex, a few herbarium specimens of what appeared to be a new species from Costa Rica and Panama were encountered. Subsequent field collecting by the junior author confirmed t...

There is general consensus that the impacts of climate change on agriculture will add significantly to the development challenges of ensuring food security and reducing poverty, particularly in Africa. While these changes will influence agriculture at a broad scale, regional or country-level asse...
