Resumo: | The objective of this work was to assess the efficiency of different methods of environmental stratification, the representation level of the evaluation places, and the adaptability and stability of soybean genotypes, through yield trials in the Paraná and Santa Catarina States, Brazil, in the agricultural years of 2000 to 2003, totaling 15 environments. For environmental stratification, the Lin's traditional method and factor analysis, allied to percentage of the simple portion (SP%) of genotype vs. environment interaction (GxE), were utilized. Adaptability and stability of the genotypes were determined by linear and bisegmented regression models. Twenty one soybean genotypes were evaluated on randomized complete blocks design, comprising three replications, and the analyzed variable was grain yield. RB 605 genotype is highly adapted and presents high yield. According to both methods, Palotina and Brasilândia do Sul localities can be reduced to one trial location. The factor analysis allied to SP% of GxE interaction is more selective to environmental stratification in relation to the Lin's traditional method. |

Foram utilizados, para estratificação ambiental, o método tradicional de Lin e a análise de fatores aliada ao porcentual de parte simples (PS%) da interação genótipo vs. ambiente (GxA). Na determinação da adaptabilidade e estabilidade dos genótipos, foram utilizados modelos baseados em regressão linear única e bissegmentada. Foram testados 21 genótipos de soja em delineamento de blocos ao acaso com três repetições, na avaliação da produtividade de grãos. O genótipo RB 605 apresenta ampla faixa de adaptação com elevada produtividade média de grãos. De acordo com ambos os métodos, as localidades de Palotina e Brasilândia do Sul podem ser reduzidas a somente um local de ensaio.A análise de fatores associada ao PS% da interação GxA é mais seletiva para estratificação ambiental, em relação ao método tradicional de Lin.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMendonça, OsmairPípolo, Valéria CarpentieriGarbuglio, Deoclécio DomingosFonseca Junior, Nelson da Silva2007-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7734Pesquisa Agropecuaria Brasileira; v.42, n.11, nov. 2007; 1567-1575Pesquisa Agropecuária Brasileira; v.42, n.11, nov. 2007; 1567-15751678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7734/4653info:eu-repo/semantics/openAccess2014-10-13T19:29:47Zoai:ojs.seer.sct.embrapa.br:article/7734Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-13T19:29:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
