Abstract

Quinoa (Chenopodium quinoa Willd.) Shows great genetic variation, both molecular and morphological, whose organization remains little known. By means of ANOVAs and dendrogram we characterize the structure of the variation of registered morpho-phenological markers from the emergency until the physiological maturity in seven populations of quinua cultivated two years in common garden. The results show that the morpho-phenological variance is concentrated in population and family levels, when traits related to biomass production show high variation at the interindividual level. These results have agroecological implications related to the geographical origin of the populations. Comparison of phenotypic and molecular classifications suggests that there is no genetic erosion in quinoa populations sampled.
