The present study was carried out in 23 communities of the municipality of Sébaco, producers of basic grains and members of the Federation of Associations for the Strategic Development of Sébaco (FADESE). The objective was to identify the use of native seeds of basic grains, an alternative that contributes to the protection of the genetic biodiversity and food safety in Sébaco Valley, Nicaragua. For information collection and analysis, a non probabilistic sampling of a finite population was used, taking into account social and productive variables. The producers in the zone in study use four native varieties of Zea mays, six of Phaseolus spp. and three Sorghum spp. The highest yielding native variety of Z. mays was Tatoscame with 1.65 t/ha. The Phaseolus variety Poneloya yielded 0.80 t/ha, and for Sorghum spp. the variety Añero had the highest yield, 1.71 t/ha.
