Key locations for soybean genotype assessment in Central Brazil

Abstract: -The objective of this work was to identify key locations for the establishment of soybean (Glycine max) genetic breeding programs, in the Central Region of Brazil. Grain yield data of three maturity groups of soybean genotypes, from regional trials conducted over three years, at 18 locations in Brazilian Cerrado were used. A key location for the early phases of the breeding program was defined as the site that best classifies the winning genotypes in the region. Key locations for the final phases were defined… Show more

“…Há muitos trabalhos sobre interação GxA em soja (Alliprandini et al, 1994;Pacheco et al, 2009;Barros et al, 2010). Em sua maioria, são estudos direcionados à avaliação da adaptabilidade e estabilidade fenotípica de cultivares, e uma parte menor é dirigida à estratificação de ambientes ou zoneamento ecológico.…”

“…Define-se como estrato ambiental um grupo de locais, contíguos ou não, pertencentes a uma mesma região de cultivo, dentro da qual a interação GxA é pequena ou não significativa (Gauch Junior & Zobel, 1997). Nesta linha de pesquisa, merece ser ressaltada a estratificação estabelecida por Pacheco (2004), reportada em Pacheco et al (2009), na qual foi utilizada uma base de dados semelhante à empregada no presente trabalho. O autor recomendou três estratificações, congêneres aos grupos de maturação: precoce (oito estratos), médio (seis) e tardio (sete).…”

“…Moreover, the efficiency and accuracy of cultivar selection for a given trait are greatly enhanced when performed at highly discriminating locations (Blanche and Myers, 2006;Yan et al, 2010). Another important aspect is homogeneous locations possibly found in a region, which can be redundant for the breeding programs in the same ME (Pacheco et al, 2009). Another important aspect is homogeneous locations possibly found in a region, which can be redundant for the breeding programs in the same ME (Pacheco et al, 2009).…”

“…In addition, an ideal test location should also be representative of the target growing region or ME (Lubbers, 2003;Mohammadi and Amri, 2012). Another important aspect is homogeneous locations possibly found in a region, which can be redundant for the breeding programs in the same ME (Pacheco et al, 2009). By the elimination of redundant locations, the costs of field evaluation can be reduced without data loss for the partition and ranking of genotypes (Yan et al, 2007;Zhe et al, 2010;BaduApraku et al, 2012).…”

“…In this way, a large number of lines are tested at these sites and only those with superior performance are subsequently tested in the other environments. Examples with common bean in the state of São Paulo are described by Carbonell and Pompeu (1997), with soybean in Paraná by Mendonça et al (2007), soybean in Central Brazil by Pacheco et al (2009) and with corn in seven Brazilian states by Oliveira et al (2010).…”
