“…We observed that shoot length did not exceed 80.0 cm among individuals, although Spehar and Santos (2002) described the average height of plants of the cultivar BRS Piabiru is 190 cm. The sowing at times that provide the occurrence of low temperatures during the crop vegetative stage causes smaller heights during the development of plants (Vasconcelos et al, 2012). In this study, such a relationship was found, since we observed the occurrence of low temperatures during the vegetative stage (Fig 1), resulting in lower plants.…”

“…There are reports of commercial crops in Brazil, specifically in the Central-West region. However, there are studies seeking to evaluate the viability of its cultivation not only in the Brazilian Cerrado, but also in southern states (Vasconcelos et al, 2012;Vasconcelos et al, 2013). Quinoa (Chenopodium quinoa Willd) is the only vegetable food that has all essential amino acids, micronutrients and vitamins.…”

Quinoa (Chenopodium quinoa Willd) an annual grain crop belonging to the Amaranthacea family is the only vegetable food that contains all essential amino acids, micronutrients and vitamins. The study aimed to evaluate the performance, growth and seed physiological quality of two genotypes of quinoa in Southern Rio Grande do Sul region. The cultivar BRS Piabiru and one breeding line were grown at green house. The design was completely randomized with four replications and five harvest times during the vegetative stage of the crop. The variables were shoot length, number of leaves, leaf area index, dry matter of aerial parts, dry matter of root and total dry matter of plant. It was concluded that the line and BRS Piabiru have slow initial growth in the first 30 days and strong growth up to 120 days. The breeding line and commercial cultivar showed the same potential for seed production in the temperate climate of this region.

“…The overall average values found for productivity (1,155.08 kg ha in the combined analysis - Table 1) compared to the mean value found by Vasconcelos, Vasconcelos, Balan, and Silvério (2012) during an experiment performed with quinoa in the city of Campo Mourão, Paraná State, which was 846 kg ha -1 , demonstrates the need to perform a selection for this characteristic in west Paraná. According to Spehar (2007), quinoa can reach productivity averages up to 3,000 kg ha The variable cycle averaged 134, 101 and 120 days, for environment 1, environment 2 and combined analysis, respectively (Table 1).…”

ABSTRACT. Quinoa has been gaining attention because of its nutritional quality, low cholesterol and lack of gluten; in Brazil, the cultivation efforts in the different regions are mainly related to breeding. This study aimed to determine the genetic parameters and evaluate the productivity of the different genotypes of quinoa for detecting genotypes amenable to selection. The experiment was conducted in crop years 2010/11 and 2011/12 in environment 1 and environment 2, respectively. In environment 1, the evaluation of 61 genotypes was performed, and in environment 2, 31 genotypes were evaluated. The experimental design was a randomized block with two replications; each plot measured 2.0 x 5.0 m (10 m²) and consisted of four rows spaced at 0.45 m. Data collected on the productivity, plant height at maturation and growth cycle were analyzed using an analysis of variance, average tests and estimates of the genetic parameters. The genotypes N24 and N08 were the only genotypes more productive than the other 46 genotypes, with values of productivity of 1,446.23 and 1,428.93 kg ha -1 and with a growth cycle of 117 and 111 days, respectively. The heritability values determined demonstrate the possibility of genetic gain using joint selection that involves two environments.Keywords: Chenopodium quinoa, genotypic selection, agronomic performance.Parâmetros genéticos e produtividade de quinoa no oeste do Estado do Paraná, Brasil RESUMO. A quinoa possui destaque devido à sua qualidade nutricional, baixo colesterol e ausência de glúten; no Brasil, os esforços em seu cultivo, nas diferentes regiões, estão relacionados principalmente ao melhoramento. O presente trabalho objetivou determinar os parâmetros genéticos e avaliar a produtividade de diferentes genótipos de quinoa com o propósito de detectar genótipos passíveis de seleção. O experimento foi realizado nos anos agrícolas de 2010/11 e 2011/12, caracterizando ambientes 1 e 2, respectivamente. Dentro do ambiente 1, realizou-se a avaliação de 61 genótipos, no ambiente 2, foram avaliados 31 genótipos. O delineamento experimental adotado foi o de blocos casualizados com duas repetições, cada parcela medindo 2,0 x 5,0 m (10 m²) sendo constituída de quatro linhas espaçadas de 0,45 m. Com os dados de produtividade, altura de plantas na maturação e ciclo, foram realizadas análise de variância, teste de média e estimado os parâmetros genéticos. Os genótipos N24 e N08 foram os únicos a superar a produtividade de outros 46 genótipos, apresentando valores de produtividade de 1.446,23 e 1.428,93 kg ha -1 , com ciclo de 117 e 111 dias, respectivamente. Os valores de herdabilidade determinados demonstram a possibilidade de ganho genético com a seleção conjunta, envolvendo os dois ambientes. Palavras-chave:Chenopodium quinoa, seleção de genótipos, desempenho agronômico.

El diseño de alimentos funcionales a partir de productos vegetales muy estudiados como la soja (Glycine max [L.] Merr.) y la potencialización de productos ancestrales como la quinoa (Chenopodium quinoa Willd.) son estrategias factibles para contrarrestar la desnutrición mundial. El objetivo de la presente revisión es describir las características agroecológicas, de composición, nutricionales y tecnológicas de estas dos especies vegetales diferentes (leguminosa y pseudocereal), basado en las publicaciones previas. Se realizó una revisión en bases de datos (Scopus, Web of Science, Scielo) y se complementó con una búsqueda manual en Google Scholar y páginas web de instituciones acreditadas. Los estudios incluidos (n=117) en esta revisión muestran que la soja se adapta mejor a altitudes bajas (~1.000m s. n. m.), mientras que la quinoa lo hace en un rango de mayores altitudes (500-4.000m s. n. m.) con mayor tolerancia a heladas. Ambas son fuente de una alta calidad proteica por suplir los requerimientos de aminoácidos esenciales sugeridos para niños y adultos sin diferencias significativas (p>0,05), particularmente triptófano y lisina y por los altos porcentajes de digestibilidad (>70%). Sus concentraciones bajas de prolaminas y aceptables de Fe, Zn, Ca, daidzeína y genisteína los convierten en productos de interés para la industria alimentaria. PALABRAS CLAVE
