ESPITIA RANGEL, Eduardo; ESCOBEDO LOPEZ, Diana; MAPES SANCHEZ, Emma Cristina  and  NUNEZ COLIN, Carlos Alberto. Priority areas to collect Amaranthus germplasm in Mexico based on diversity and species richness. Rev. Mex. Cienc. Agríc [online]. 2010, vol.1, n.4, pp.609-617. ISSN 2007-0934.

This investigation had as objective to use the Geographical Information System, to create maps of indexes of diversity and wealth of species of genus Amaranthus in Mexico, to plan the best areas of germplasm collection. The maximum wealth of species was in west center of State of Mexico including Distrito Federal and the Pacific coast, between Jalisco and Colima, as well as in Sinaloa. The Brillouin index of biodiversity showed high diversity in the Pacific coast, Sinaloa, between the states of Jalisco and Colima, also the west center of Nuevo León, the region of Huasteca of southeast of Tamaulipas and northeast of Veracruz, as well as the northwest area of Yucatán Peninsula. The priority areas proposed are: the central coast of Sinaloa, south of biogeographic region of Sonora, west center section of State of Mexico including Distrito Federal, biogeographic region of Mexican Trans-Volcanic Belt and central Pacific coast between states of Jalisco and Colima, finally in biogeographic region of Mexican Pacific coast.

Keywords : amaranth; estimators for wealth of species; indexes of diversity; SIG.
