“…The interaction between genotype and environment indicates that the genotypes do not have to be a constant for all evaluation environments; in this way, it is important to determine the G×E interaction. Most quantitative traits, such as productivity, are of polygenic nature and are influenced by the environment where the G×E interaction exerts great influence on the expression of quantitative traits (SCHMILDT et al, 2011). According to Barros et al (2010a), confirmed interactions are problematic for breeding programs for both the selection phase and for the recommendation of cultivars.…”

“…Furthermore, the AMMI and GGE analysis enables the graphical representation of genotypes and environments in a multivariate scattergram (biplot). These diagrams provide information on the stability and phenotypic adaptability, and permit the agronomic zoning and choice of specific environments for the evaluation and selection of cultivars, as they have been used in studies of this nature in soybean (MEOTTI et al, 2012;STÜLP et al, 2009;YOKOMIZO et al, 2013) and in other cultures (MIRANDA et al, 2008;SCHMILDT et al, 2011;SUBEDI et al, 2007). Therefore, this study aimed to investigate the adaptability and phenotypic stability of 10 soybean genotypes in 12 environments in Paraná using the AMMI and Eberhart and Russell models.…”

This study aimed to evaluate the adaptability and phenotypic stability of 10 soybean genotypes in 12 environments in Paraná state by using the additive main effects and multiplicative interaction analysis (AMMI) and Eberhart and Russell models. The assays were conducted in a randomized complete block design with three replicates, in the 2010/2011 season in four locations in Paraná state (Assaí, São Pedro do Ivaí, Cornélio Procópio, and Marilândia do Sul), and with three sowing dates (15/-20/10/10; 29/10-03/11/10; 15/-20/11/10). The cultivars tested with Roundup Ready® technology included SYN 1049, SYN 1152, SYN 1059, SYN 3358, SYN 1163, SYN 1157, V-MAX, FT Campo Mourão, BMX Potência, and SYN 9070. The yield character was analyzed. Data were submitted to analysis of variance and the adaptability and stability were then analyzed. The results of the AMMI and Eberhart and Russell models were somewhat consistent for the stability parameter only. The AMMI analysis was able to capture 66% of the variance associated with residue no additives, of which 43.18% was retained in the first principal component of interaction and 23.58%, in the second component. This is sufficient to explain the genotype × environment interaction. The SYN 1059, SYN 1163, and VMAX genotypes are distinguished by their considerably higher yield and productive adaptation. In the AMMI analysis, the cultivar SYN 1163 showed commercial promise among the other cultivars for high grain yield performance, adaptation, and response predictability. Key words: Biometric models.

The objective of this study was to identify, among the 27 hybrids evaluated, the best adaptability and stability responses for corn grain yield in five environments. The experiments were conducted in the 2009/2010 crop seasons in a randomized complete block design with three replications. There was significant G x E interaction effects (p ≤ 0.05) only for the yield and cob mass characters. Among the hybrids tested, 14 of them were ranked as responsive to environmental improvement for grain yield. The other genotypes have good performance in harsh environments. For the stability analysis, significance was found for the hybrids 5, 7 and 27. For cob mass, all hybrids showed significant adaptability, for stability, only genotypes 20 and 24 expressed significance.

“…O ajuste do rendimento para o estande ideal, por regra de três simples, constitui um procedimento inadequado, por não existir proporcionalidade linear entre o número de plantas e a produtividade observada, superestimando o rendimento de diferentes genótipos (Ávila & Sanches 1978, Vencovsky & Cruz 1991, Schmildt 2000.…”

INTRODUÇÃOA magnitude do erro experimental tem efeito direto no sucesso de experimentos, no melhoramento de plantas, sendo que vários fatores interferem nesta magnitude. Os experimentos devem ser conduzidos com o maior rigor possível, para que tenham boa precisão e, assim, as diferenças fenotípicas representem as genotípicas. Há vários fatores que afetam a precisão experimental, como a heterogeneidade do solo, tamanho da parcela, delineamento adotado, número de repetições e condução dos experimentos (Ramalho et al. 2005). ABSTRACT RESUMOA variação de estandes, nas unidades experimentais, é outra dificuldade na análise e interpretação de resultados, em programas de melhoramento de plantas. Por isto, tenta-se obter estandes uniformes pela semeadura em excesso, efetuando-se o desbaste para o estande desejado, quando as plantas estão em estádio inicial de crescimento. Porém, mesmo com esta prática, a parcela pode apresentar falhas, por causa da elevada precipitação pluvial, ou ação de pragas e doenças, o que pode afetar a realização de certas análises estatísticas, em particular quando o caráter não é medido apenas nas plantas competitivas (Vencovsky & Cruz 1991, Ramalho et al. 2012.
