| description | Northern aboriginal communities from Argentina cultivate maize landraces for self-sufficiency. Genetic characterization of indigenous germplasm from Misiones Province is extremely limited. To contribute to the knowledge and conservation of the genetic diversity of these native maize landraces and to assess their potential as a reservoir of novel alleles, 467 individuals were evaluated using 15 nuclear microsatellite loci. The results of this study allow to conclude that: 1) landraces from Misiones can be divided into two different gene pools, which are consistent with the type of corn (flints and flours vs. popcorns), these should be regarded as different conservation units; and 2) Misiones landraces represent a significant reservoir of diversity, useful to broaden the genetic base of breeding programs. |

Genetic characterization of indigenous germplasm from Misiones Province is extremely limited. To contribute to the knowledge and conservation of the genetic diversity of these native maize landraces and to assess their potential as a reservoir of novel alleles, 467 individuals were evaluated using 15 nuclear microsatellite loci. The results of this study allow to conclude that: 1) landraces from Misiones can be divided into two different gene pools, which are consistent with the type of corn (flints and flours vs. popcorns), these should be regarded as different conservation units; and 2) Misiones landraces represent a significant reservoir of diversity, useful to broaden the genetic base of breeding programs. En el norte de la Argentina habitan comunidades aborígenes Guaraníes que cultivan razas nativas de maíz. La caracterización genética del germoplasma autóctono, en particular de las razas de la Provincia de Misiones, es sumamente escasa. Con el fin de aportar al conocimiento de la diversidad genética y la estructura poblacional de estas razas nativas, contribuir a su conservación y evaluar su potencial como reservorio de nuevos alelos, se evaluaron 15 loci microsatélites nucleares en 467 individuos. Los resultados del presente estudio permiten concluir que: 1) Las razas de Misiones se encuentra n constituidas por acervos génicos diferentes, que concuerdan con el tipo de grano que poseen, es decir, harinosos/córneo-harinosos y reventadores, grupos que deberían ser considerados como unidades de conservación diferentes; y 2) las razas nativas de Misiones constituyen una reserva de diversidad significativa, con potencial para ampliar la base genética de los programas de fitomejoramiento.
