Landraces and bean (Phaseolus vulgaris L.) cultivars grown in Mexico are diverse, as are consumer preferences and agroecological production environments. Mexican common bean cultivars were analyzed using amplified fragment length polymorphism (AFLP) fingerprinting to examine the genetic relationships within and among races, based on the genotyping of 112 bred cultivars developed in Mexico.

Molecular analysis of dry bean germplasm will be useful to corroborate previous cuitivar characterizations and establish the genetic basis of improved germplasm, to facilitate the use of that diversity, ...
