| Twenty six breeding lines, selected from individual plant progenies of hybrids among varieties Amarilla de Marangani, Blanca de Junín, Chewecca, Faro 4, Improved Baer, Kancolla, Real, and Salares-Roja, had their agronomic characters evaluated, in Planaltina, DF, Brazil (15º36'S and 47º12'W), 1,000 masl, in randomized complete blocks, on a Ferralsol, previously limed and fertilized. Grain yield was positively associated with plant height, inflorescence length and diameter, and plant cycle. Genetic gain can be attained by selection based in these characters for commercial production of quinoa in tropical regions. |

| Abstract: The objective of this work was to evaluate the growth dynamics of the cover plants amaranth (Amaranthus cruentus), quinoa (Chenopodium quinoa), and millet (Pennisetum glaucum) in a Typic Acrustox, under different water regimes in the Brazilian Cerrado. The cultivation was carried out in the winter, with reduced rainfall, which facilitated the application of varying irrigation depths to the different crops. Water regimes denominated lower, lower middle, upper middle, and upper - corresponding to 217, 386, 563, and 647 mm water depths, respectively - were tested by means of an irrigation bar composed of sprinklers with different flow rates. Plant growth was quantified by weekly collections. Amaranth was the most responsive plant to water. Quinoa... |

| Background Currently, the technology called Clearfield® is used in the development of crops resistant to herbicides that inhibit the enzyme acetohydroxy acid synthase (AHAS, EC 2.2.1.6). AHAS is the first enzyme of the biosynthetic pathway that produces the branched-chain of the essential amino acids valine, leucine, and isoleucine. Therefore, multiple copies of the AHAS gene might be of interest for breeding programs targeting herbicide resistance. In this work, the characterization of the AHAS gene was accomplished for the Chenopodium quinoa Regalona-Baer cultivar. Cloning, sequencing, and Southern blotting were conducted to determine the number of gene copies. Results The presence of multiple copies of the AHAS gene as has been shown previously in... |

| Quinoa (Chenopodium quinoa Willd.) in Chile represents a source of germplasm with high nutritional value. However, there is little information available related to quinoa seed quality grown under contrasting environments. In this study we evaluated the changes on seed composition of seeds of two lowland/coastal quinoa genotypes grown under arid (Vicuna) and cold-temperate (Temuco) conditions in Chile. Results showed that in the case of 'Regalona Baer' and 'Villarrica' genotypes the arid location (with irrigation) led to a significant increase (P < 0.05) in grain yield (4.2 and 5.1 t ha-1, respectively), soluble dietary fiber (16.8 ± 0.4 and 28.9 ± 2.1 g kg-1 DM, respectively), vitamin B3 (2.44 ± 0.005 and 2.26 ± 0.04 mg 100 g-1 DM, respectively),... |

| Resumen Los cultivos de quinua en el altiplano peruano se ven afectados por la enfermedad de mildiu, que puede causar pérdidas de hasta el 90 % de la producción. El objetivo de este estudio es evaluar el efecto de cepas de Trichoderma sp. y microorganismos eficaces (ME) en el control del mildiu y rendimiento de la quinua. En el terreno experimental del Centro Internacional de la Papa (CIP), Camacani de la Universidad Nacional del Altiplano del departamento de Puno, en la campaña agrícola 2016-2017, se sembraron semillas control y otras paletizadas con ocho tratamientos: cuatro cepas de Trichoderma sp., tres dosis de ME (5 %, 10 % y 15 %) y una mezcla de las cepas de Trichoderma sp. y ME (15 %), posteriormente se realizaron cuatro aplicaciones foliares de... |

| Abstract Background: The analysis of information generated from experiments involving different treatments, can be done by multivariate statistical analysis techniques, such as discriminant analysis, to analyze data obtained from predefined groups. Objective: Verify, through discriminant analysis, the differences among cover crop (Avena strigosa, Chenopodium quinoa, Cichorium intybus, and fallow land) treatments with respect to main crop soybean yield. Methods: For weed control, these cover crops were subjected to different management techniques, namely mowing, the application of glyphosate or the application of paraquat. The experimental design consisted of completely randomized blocks in a 4 × 3 × 2 factorial scheme, with four replications, consisting... |

| The objective of this work was to compare the physicochemical characteristics of quinoa and flaxseed bread. Sensory acceptance, color and texture were also appraised. They showed appropriate balances between their content of polyunsaturated and saturated fatty acids and low levels of trans fatty acids. Flaxseed bread had larger amounts of mono and polyunsaturated fatty acids, omega-6 and omega-3, as well as a more balanced omega-6/omega-3 ratio. Quinoa bread, on the other hand, had the advantage of presenting smaller contents of saturated fatty acids. With regard to color and texture, quinoa bread had similar characteristics to the flaxseed bread. The quinoa bread was well accepted by the consumers, who expressed high interest in buying it. |
