“…Table 1. The great number of environments promotes the choice of genotypes more adapted (Benin et al 2013). Although cultivar CD 1550 was registered in early 2012, it was maintained in the VCU trials of 2012 and 2013.…”

“…Assim, o método de Papadakis, realizado com base na análise de covariância, em que a covariável é determinada como a média das estimativas dos erros nas parcelas vizinhas (variação espacial), mostrou-se eficiente para a comparação da produtividade de grãos de genótipos de trigo (Benin et al, 2013) e de soja (Storck et al, 2008). Estudos relacionados a métodos de análise espacial (Duarte & Vencovsky, 2005), para as culturas de chá (Peiris et al, 2008), feijoeiro (Souza et al, 2000), feijoeiro e milho (Costa et al, 2005) e laranjeira (Maia et al, 2013) foram realizados e, de maneira geral, relataram a melhoria da eficiência na seleção de genótipos.…”

“…For these cases, most appropriate designs and analysis methods are reported, e.g., single and triple lattice designs (RAMALHO et al, 2000) and the Papadakis spatial analysis method. This was applied in various cases with a smaller number of soybean genotypes (VOLLMAN et al, 2000;STORCK et al, 2008;BENIN et al, 2013), showing significant accuracy gains when compared to the random complete block design. Appropriate measures to assess the experimental precision in bean and soybean genotypes competition assays were studied (CARGNELUTTI FILHO et al, 2009), and they can be used to identify the best planning and data analysis.…”
