Genetic diversity in maize landraces from indigenous settlements of Northeastern Argentina

In South America, native maize germplasm has been extensively studied particularly for the Andean region. However, relatively few genetic diversity studies include materials from the eastern region of the continent. Herein we present a genetic diversity characterization of four Popcorn maize landrac...

Herein we present a genetic diversity characterization of four Popcorn maize landraces, maintained in indigenous settlements, from Northeastern Argentina (NEA).

For the whole data set, a total of 65 alleles were found, with an average of 7.22 alleles per locus. The average gene diversity was 0.370.

The results presented will be useful to design strategies that maximize the utility of maize genetic resources. © 2008 Springer Science+Business Media B.V. 2009 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00166707_v135_n1_p39_Bracco http://hdl.handle.net/20.500.12110/paper_00166707_v135_n1_p39_Bracco
