ResumenThe predominant criteria for defining and identifying races of the genetic complex of Zea mays L. are based on morphological and agronomic attributes along with geographic distribution. In some occasions these present inconsistencies with respect to the authentic genetic identity of the populations. The molecular methods can reveal in detail the identity and variability of individuals and populations through genetic footprints, thus their application in the identification and characterization of races offers advantages. The objective of the present study was to determine the genetic diversity of maize landraces of northern Mexico through microsatellites. The diversity, allelic profile and genetic structure of eight maize landraces of northern Mexico (Apachito, Azul, Conico Norteno, Cristalino de Chihuahua, Raton and Tuxpeno Nortetio) and one of teosinte (Zea mays ssp. parviglumis Iltis and Doebley)) were determined by means of analysis of microsatellites (SSR). Twenty-five individuals of 63 accessions of the abovementioned races were evaluated using 31 loci of SSR. The parameters of genetic diversity estimated were total number of alleles, number of alleles per locus, proportion of polymorphic loci, expected heterozygosity and genetic structure of the populations using the Wright's F-statistics. The distribution of diversity was determined through principal coordinates and cluster analyses. In total 570 alleles were found, with an average of 18.3 per locus and 87.9 \% of polymorphic loci. A 75.6 \% of the genetic diversity resides within the populations of the maize races cultivated in northern Mexico and the remaining 24.4 \% among populations of these races. The molecular markers grouped the accessions in races in a form that was only partially concordant with respect to the traditional classification.es_ES
