Resumo: | The objetive of this study was to evaluate the stability and adaptability of soybean (Glycine max (L.) Merrill) cultivars in five different planting dates. The tests were composed by 21 cultivars outlined in a random blocks design, with three replicates, conduced in 1996/97 by Embrapa-Centro de Pesquisa Agroflorestal de Rondônia, in a field of Vilhena, RO, Brazil. The used methods showed accordance between the achieved results, being the behavior of cultivars in different times of sowing represented by a linear model. The coefficient of linear regression b1i did not show any significant difference of the unit by the t test for all the tested cultivars (P < 0.05). The cultivars which presented significant regression deviation s2(di) (P < 0.05) were MT/BR-50 e EMBRAPA 31, R2 = 58.56% e 74.43%, respectively. The other cultivars did not present any significant regression deviation. |

Merrill), em cinco épocas de plantio no cerrado de Rondônia. O delineamento experimental foi blocos ao acaso, com três repetições. Os ensaios foram conduzidos no ano de 1996/97 pelo Centro de Pesquisa Agroflorestal de Rondônia, no Campo Experimental de Vilhena em Rondônia, RO. Os métodos utilizados apresentaram concordância entre os resultados alcançados, sendo que o comportamento das cultivares nas diferentes épocas de semeadura pode ser representado por um modelo linear. O coeficiente de resposta linear b1i não apresentou diferença significativa (P < 0,05) da unidade pelo teste t (b1i = 1) em todas as cultivares testadas. As cultivares que apresentaram desvios de regressão s2(di) significativos (P < 0,05) foram MT/BR-50 e EMBRAPA 31, com R2 = 58,56% e 74,43%, respectivamente. As demais cultivares não apresentaram desvios de regressão significativos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPrado, Eloi Elias doHiromoto, Dario MinoruGodinho, Vicente de Paulo CamposUtumi, Marley MaricoRamalho, André Rostand2001-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6177Pesquisa Agropecuaria Brasileira; v.36, n.4, abr. 2001; 625-635Pesquisa Agropecuária Brasileira; v.36, n.4, abr. 2001; 625-6351678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6177/3242info:eu-repo/semantics/openAccess2010-08-09T12:47:47Zoai:ojs.seer.sct.embrapa.br:article/6177Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-09T12:47:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
