IN THE NORTHERN SABANA OF BOGOTA. rev.udcaactual.divulg.cient. [online]. 2016, vol.19, n.2, pp.325-332. ISSN 0123-4226.

Quinoa, Chenopodium quinoa Willd. is a dicotyledoneous plant, considered a pseudocereal, according to growth characteristics and forms of consume, has become of worldwide interest in recent years due to its high nutritional quality and wide ecological adaptation. In order to contribute to the knowledge of the crop, performance characteristics, quality, morphological variation and phenological development of three accessions of quinoa, Piartal, Nariño and Bolivia were evaluated. The study was conducted under conditions of the U.D.C.A, located in the north of Bogotá, with geographical coordinates 4° 35' latitude north and 74° 04' latitude west during a production cycle. The results showed differences in plant yield, protein content, and stem color characteristics, panicle shape and physiological maturity. The yield ranged from 140.09 to 260,74g per plant, the highest yield was obtained with the Piartal accession, which also showed the shortest phenological development, six months. The accessions evaluated showed high phenotypic homogeneity within materials, allowing its direct use in commercial crops, as well as parentals for hybridization in breeding programs.
