Con el proposito de proveer informacion acerca de la variabilidad genetica y la adaptacion en la Sabana de Bogota de la coleccion de quinua correspondiente a la Prueba Americana y Europea de Quinua, se evaluaron 19 cultivares mediante 49 caracteristicas morfologicas y agronomicas. El ensayo se realizo en el Centro Agropecuario Marengo, de la Universidad Nacional de Colombia, ubicado en Mosquera (Cundinamarca). El analisis estadistico mostro que los ocho primeros componentes explican el 88,12.

Forty-nine morphological and agronomic characteristics were evaluated at Research Center Marengo of National University of Colombia, located at Mosquera (Cundinamarca). The main objective of this experiment was to study the genetic variability of quinoa cultivars from american and european countries. The statistical analysis was carried out with 35 out of 49 variables. The first eight components explained the 88.12 per cent of total variation and were constituted by 18 variables. Using this information a dendogram was constructed. Nine groups were identified. Cultivars from american countries were separated from europeans ones. The best cultivars were E-DK-4 and G-205-95 from Denmark. These presented high grain yield, high level of biomass, precocity and low height plant. Key word: Andean grains, multivariate analysis, cluster analysis.
