The aim of this experiment was to understand the physiological basis of genotype by environment by management interaction in quinoa. Experiments were carried out at four environments combining two locations (Valleys and Puna) and two years (2017 and 2019 for Valleys, 2018 and 2019 for Puna). Local genotypes (RQ252 from Valley and RQ420 from Puna) plus Sea Level cultivars (Titicaca and Puno, adapted to low altitude and high latitude environments) were compared under plant densities of 7 and 14 pl m-2 evaluating yield, biomass accumulation and harvest index. Despite of the changes in plant density, the correlations between yield and biomass in Valleys (R2= 0.68, p
