“…The effects over the analyzed characteristics express high genetic variability of this crop [7] [27], originated from the Andes mountain region, which presents extreme edaphoclimatic conditions and, because of this, elevated levels of tolerance to adversity and environmental variation on its genotypes, which respond differently to some managements, such as nitrogen fertilization, irrigation and sowing time [9] [14].…”

“…The search for genotypes, more adapted to different regions and conditions of the state of Parana [14] is important to the consolidation of this crop. [7] [15] reported that the interaction genotype-environment and the cultivar variability reflect the heterogeneity of the genetic material, making it possible to identify promisor materials and to indicate adapted genotypes [14].…”

The objective of this research was to evaluate the agronomic performance and productivity of sixteen genotypes of Chenopodium quinoa cultivated in agroecological and conventional production systems. The evaluations were carried out, based on agronomic characteristics and yields of sixteen C. quinoa genotypes, grown in two simultaneous experiments, in an agroecological production and a conventional production system carried out at the town of Entre Rios do Oeste, Paraná, Brazil in the harvest 2015/16. Each experiment was composed of three replicates, following the randomized block design. Number of plants in flowering, number of plants per linear meter, height of insertion of the first panicle, number of days for maturation and productivity were the parameters evaluated. The data were submitted to statistical analysis with the aid of the GENES computational application. Genotype Q13-24 showed a more suitable production for the conventional production system. While the genotype Q13-01, presented the increase of productivity, being more indicated to the system of agroecological production. The characteristics height of plant flowers (HPF) and height of insertion of the first panicle (HIP) had higher values when the plants were cultivated in a conventional system. The number of plants per linear meter (NPLM) was higher in the agroecological crop, when compared to conventional cultivation. The same quinoa genotype can behave differently depending on the area management, being a productivity and the genotype cycle depends on the production system and the genotype used.

“…Genotype selection yield gain for productivity, agronomic traits, disease resistance (Leite et al, 2016), and soybean seeds quality (Vasconcelos et al, 2012) is reported in several studies. In addition, gain reports have been made in genotype selection in other crops, like common bean, hence, plant architecture productivity (Matos et al, 2007;Faria et al, 2014) and also for seeds quality (Perina et al, 2010).…”

ABSTRACT.Estimating genotype x environment (GxE) parameters for quality and yield in soybean seed grown in different environments in Minas Gerais State was the goal of this study, as well as to evaluate interaction effects of GxE for soybean seeds yield and quality. Seeds were produced in three locations in Minas Gerais State (Lavras, Inconfidentes, and Patos de Minas) in 2013/14 and 2014/15 seasons. Field experiments were conducted in randomized blocks in a factorial 17 x 6 (GxE), and three replications. Seed yield and quality were evaluated for germination in substrates paper and sand, seedling emergence, speed emergency index, mechanical damage by sodium hypochlorite, electrical conductivity, speed aging, vigor and viability of seeds by tetrazolium test in laboratory using completely randomized design. Quadratic component genotypic, GXE variance component, genotype determination coefficient, genetic variation coefficient and environmental variation coefficient were estimated using the Genes software. Percentage analysis of genotypes contribution, environments and genotype x environment interaction were conducted by sites combination two by two and three sites combination, using the R software. Considering genotypes selection of broad adaptation, TMG 1179 RR, CD 2737 RR, and CD 237 RR associated better yield performance at high physical and physiological potential of seed. Environmental effect was more expressive for most of the characters related to soybean seed quality. GxE interaction effects were expressive though genotypes did not present coincidental behavior in different environments.

“…The estimation of genetic and phenotypic parameters, such as heritability, genetic and phenotypic correlation and gains with selection, is important for genetic improvement programs because these estimates facilitate the choice of methods and characters used in the initial and advanced phases of improvement programs, thereby allowing the study of mechanisms, genetic values and variability for one character (Cruz, Regazzi, & Carneiro, 2012;Vasconcelos, Reis, Sediyama, & Cruz, 2012). However, characteristics related to the quinoa cultivation have not been studied with regard to genetic values for quantity.…”

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.
