DEL CASTILLO GUTIERREZ, Carmen R  and  WINKEL, Thierry. Intra and inter population phenotypical variation in seven communities of the Bolivian Altiplano. RIIARn [online]. 2014, vol.1, n.1, pp.58-64. ISSN 2409-1618.

Quinoa (Chenopodium quinoa Willd.) shows great genetic variation, both molecular and morphological, which organization remains poorly documented. Through nested ANOVAS and dendrogramme we characterized the structure of the variation in morpho-phenological traits registered from seedling emergence until plant maturity in seven quinoa populations grown in common garden for two years. Results show that the variance in morpho-phenological traits was concentrated at the population and family levels, while traits related to biomass production showed high inter-individual variation. These results have agroecological implications related to the geographic origin of the populations. A comparison of phenotypic and molecular classifications suggests that there is no genetic erosion in the sampled quinoa populations.
