| Popis: | In the department of Boyacá, seeds of Chenopodium quinoa Willd. are planted, which correspond to a mixture of varieties, producing different grain sizes and saponin concentrations, affecting the quality and yield of the derived products, and therefore their commercialization, whenever the buyer requires it for a certain purpose, sweet varieties for bakeries or with high contents of saponin for the detergent industry. The objective was to compare the morphological characters, to identify the six varieties, according to the constant and conspicuous characteristics, as well as physiological parameters in the reproductive and vegetative stages. Observations were made in the different stages of development; in seeds, germination tests were made, the diameter and weight were measured; In the seedling stage, the total height, hypocotyl length, cotyledon lamina length and changes in red pigmentation were determined, qualitatively evaluated by direct observation. In adult plants, reproductive and vegetative characters were reviewed. A taxonomic key was proposed for the identification of the varieties. Blanca Real recorded the highest germination percentage (98%). Amarilla Marangani presented the seeds with the greatest weight and diameter and the longest cotyledons. The height of the Black and Piartal seedlings was below the other varieties. Blanca de Jericó, Blanca Real and Piartal presented weak reddish colorations in the hypocotyl and cotyledons. The identification of each variety will result in better products for growers, marketers, and processors. |
