Spatial Delimitation of Genetic Diversity of Native Maize and Its Relationship with Ethnic Groups in Mexico

Mexico, as a center of origin maize, presents high diversity maize races. With the objective spatially demarcating regions with concentration intraspecific in fundamental measure for situ conservation their agrobiodiversity, Geographic Information Systems (GIS) tools have been used to generate and richness indexes 64 races cultivated using demarcate relationships environmental factors such temperature, precipitation, altitude; presence indigenous groups; type used. These relations allowed defining seven units spatially, characteristic each them, which constitute priority areas conservation. In addition, close relationship was found between ethnic groups, from south country, associated differences use different groups. This geographical demarcation uses will favor food security through specific measures conservation, well an increase added value by-products based on conserved by local
