“…This shows relative ease in the selection of superior cultivars, as reported by Mendes et al (2012) and Silva et al (2014), when evaluating the adaptability and stability of corn hybrids in Brazil. The heritability based on the averages of the genotypes (h 2 m ) was of 0.70, which indicates a trustworthy selection of the corn cultivars, based on the predicted genotypic values.…”

“…Therefore, the coefficient of determination (R 2 GxE =0.51) confirmed the large participation of the GxE interaction in the phenotypic variance of the genotypes (Table 1). This fact was also shown by the median genotypic correlation between the performances in the various environments (r g(L) =0.31), which results in the complex part of the GxE interaction and causes certain difficulty in the selection of genotypes with a more ample adaptation, as also noted by Arnhold et al (2012) and Mendes et al (2012), in a study on the genotype x environment interaction in corn.…”

“…To facilitate the interpretation, the MHPRVG values were multiplied by the overall average of all environments (MG), which results in the same order of magnitude of the studied trait. The environments were classified as favorable and unfavorable, according to the overall average, performing MHPRVG analyses separately for each environment class, as in Mendes et al (2012). To evaluate the capacity for adaptability, which considers stability and productivity, the MHPRVGxMG results were compared in a dispersion graph, to contrast favorable and unfavorable environments.…”

“…The REML/Blup method for this kind of estimate in the corn crop has been efficiently used in the selection of promising cultivars (Arnhold et al, 2012;Fritsche-Neto et al, 2012;Mendes et al, 2012). In addition, studies developed by Arnhold et al (2012) and Silva et al (2014) show the importance of studying the GxE interaction in the corn-growing regions in Brazil, due to the great diversity of edaphoclimatic conditions in the country, as well as to the diversity of corn cultivars available in the market.…”

-The objective of this work was to evaluate corn cultivars grown in the state of Amazonas, Brazil, which simultaneously show high grain yield, adaptability, and stability. The trials were carried out in seven environments in the state of Amazonas, in a randomized complete block design, with two replicates. The grain yield of 30 corn cultivars was evaluated in four growing seasons, from 2011/2012 to 2014/2015. The genetic parameters were estimated by the REML/Blup methodology. The selection for adaptability and stability was based on the predicted genetic value and on the harmonic mean of the relative performance of the genetic values. Despite the existence of genotype x environment interaction, cultivars with high adaptability and stability were identified. Iranduba -lowland, in

Uma das formas mais utilizadas para determinar o efeito dessa interação é a implantação de experimentos em locais contrastantes, em que vários genótipos são avaliados, com vistas à identificação de materiais genéticos com ampla estabilidade e adaptabilidade (Barros et al, 2012;Mendes et al, 2012;Silveira et al, 2012).…”

O objetivo deste trabalho foi avaliar a adaptabilidade e estabilidade fenotípica e outras características de interesse agronômico de genótipos de café Bourbon Vermelho e Bourbon Amarelo, para selecionar os de melhor desempenho no Estado de Minas Gerais. Foram avaliados 17 genótipos pertencentes ao grupo Bourbon, bem pontuados em concursos de qualidade de bebida, além de três cultivares amplamente cultivadas no estado, utilizadas como testemunhas. Os experimentos foram instalados em dezembro de 2005, nos municípios de Lavras, Santo Antônio do Amparo, Três Pontas, Campos Altos e Patrocínio. As avaliações foram realizadas durante as quatro primeiras colheitas, nos anos agrícolas 2007/2008, 2008/2009, 2009/2010 e 2010/2011, e compreenderam as seguintes características: produtividade de grãos, adaptabilidade e estabilidade fenotípica, percentagem de frutos chochos, vigor vegetativo e classificação por peneira. Há variabilidade genética dentro do grupo de Bourbon estudado. Os genótipos de Bourbon apresentam produtividades satisfatórias em todos os locais avaliados. O genótipo Bourbon Vermelho 2 apresenta maior adaptabilidade, tendo-se destacado quanto a todas as características avaliadas.

Assessment of yield performance and stability of hybrids and populations of tropical maize across multiple environments in Southeastern Brazil

et al. 2023

The identification of stable genotypes with high yield in diverse multiple‐stress environments is important to increase maize (Zea mays L.) grain yield under tropical environments. Our objective was to assess the yield performance and stability of experimental hybrids and broad‐based populations of tropical maize across diverse environments in Southeastern Brazil. We evaluated two sets of maize genotypes for grain yield: 190 experimental hybrids along with 6 commercial hybrids and 45 population hybrids along with their 10 parental populations across 8 environments in Southeastern Brazil. Multiple statistical methods were used and compared in the analyses. Combined analysis of variance indicated that genotypic main effect (G), environmental main effect (E), and genotype by environment interaction were highly significant (p < 0.0001) for grain yield. The E accounted for 42% of the total variation for both hybrids and populations, and they were more similar within the growing season than between seasons, mainly for populations. Low nitrogen (N) stress was a key factor in hybrid evaluation and recommendation, particularly under drought stress conditions. Among the environment classification methods, genotype main effect plus genotype × environment interaction (GGE) biplot provided more accurate information about environments grouping and selection of the genotypes than the Eberhart and Russell method. Harmonic mean of the relative performance of the predicted genetic values (HMRPGV) based on mixed models ranked the hybrids and populations according to mean grain yield and stability, penalizing hybrids, and populations with lower stability. Therefore, we recommend the GGE biplot and HMRPGV for genotype evaluation based on multi‐environment trials data. These methods identified 92V2144 and 92V2033 as the most promising hybrids for favorable and 92V2141, 92V2153, and 92V2137 as the most promising for unfavorable environments. 92VX033 and 92VX043 were identified as broadly adapted and stable populations across multiple environments in Southeastern Brazil.
