In Ecuador, cultivation is carried out on a small scale for self-consumption and differentiated segments of organic quinoa for export. The morpho-agronomic characterization of germplasm is important to select lines and develop varieties demanded by different market segments. This study was carried out at Laguacoto Farm. The objectives were to characterize the main morpho-agronomic descriptors of eight accessions; select the best accessions with agronomic potential and generate a database. The treatments were: T1: LPQ-4, T2: Titicaca Stem Yellow, T3: Titicaca Stem Red, T4: QQ-74 Mass, T5: Puno Pasankalla, T6: CQ-407 Pasankalla, T7: Black Quinoa and T8: UEB Cream. . The characterization of morphological descriptors of the grain and the evaluation of 17 agronomic components were carried out. Analysis of variance, Tukey's test, correlation and regression were performed. The agronomic response of the germplasm was different for the grain attributes: color, flavor and size. The components that increased yield were the crop cycle, plant height, grain weight per plant and thousand grains. The treatment with the highest yield was T1: LPQ-4 with 1444 kg/ha, medium saponin content, white grain, round shape and large size. This research made it possible to select promising germplasm that is resilient to climate change to diversify production systems with LPQ-4 accessions; CQ-407 Pasankalla and Quinua Negra, for local, national and international market niches. |
