Despite the worldwide importance of cultivated cassava (M. esculenta Crantz) its origin and taxonomic relationships with other species in the genus have not been clearly established. We evaluated a representative sample of the crop’s diversity and six wild taxa with AFLPs to estimate genetic rela...

Assembled germplasm has provided breeders with valuable traits for the improvement of common beans. Molecular markers such as phaseolin and isozymes have facilitated understanding of the genus Phaseolus thus enabling breeders to develop more effective strategies. However, there are still gaps in ...

Single nucleotide polymorphism (SNP) markers are by far the most common form of DNA polymorphism in a genome. The objectives of this study were to discover SNPs in common bean (Phaseolus vulgaris L.) by comparing sequences from coding and noncoding regions obtained from the GenBank and genomic DN...

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...

Nuñas are a group of common bean (Phaseolus vulgaris, Fabaceae) varieties, whose grains are consumed after toasting in their original Andean habitats. Nowadays, these varieties are restricted to certain parts of the highlands of Peru and Bolivia. Linguistic, ethnobotanical, and archaeological dat...
