Knowledge of the center of bean domestication is important to identify a potential area of origin for agriculture several millennia ago and to better understand the genetic, physiological, and ecological characteristics of the domesticate bean gene pool. The putative Mesoamerican domestication center of Phaseolus vulgaris is located in the Lerma-Santiago Basin of Mexico. Our objective in this study is to analyze the genetic structure of wild Mexican and Andean bean populations and to study their relation with landraces of the same regions. As a first step, we are characterizing genetic diversity among these accessions with a set of microsatellite markers distributed throughout the genome followed by an analysis with the software STRUCTURE
