Resumo: Bootstrap estimates of arithmetic mean of Pickett, Peking, PI88788 and PI90763 soybean genotypes and the confidence intervals obtained through normal theory and bootstrap distribution of this estimator, like the percentile bootstrap and the BCa (bias-corrected and accelerated) of the differentiation parameter of the standard cultivar Lee for susceptibility, are utilized to classify races of soybean cyst nematode. The confidence intervals obtained from bootstrap distribution showed smaller amplitude and were very similar. Therefore, the lower limit of the bootstrap percentile confidence interval was taken as reference level in the bootstrap distribution of the arithmetic mean estimator of the differential genotypes allowing to estimate the empirical probability of a positive or negative reaction and, consequently, to identify the most probable race under specific test.

Os intervalos de confiança obtidos a partir da distribuição "bootstrap" apresentaram menor amplitude e foram muito similares, dessa forma, o limite inferior do intervalo de confiança percentil "bootstrap" foi tomado como nível de referência nas distribuições "bootstrap" do estimador da média aritmética dos genótipos diferenciadores, permitindo estimar a probabilidade empírica de uma reação positiva ou negativa, e, conseqüentemente, identificar a raça mais provável sob determinado teste.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDias, Waldir PereiraSouza, Geraldo da Silva eErivaldo Pereira, JoséVeloso Silva, João Flávio2000-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5766Pesquisa Agropecuaria Brasileira; v.35, n.2, fev. 2000; 271-275Pesquisa Agropecuária Brasileira; v.35, n.2, fev. 2000; 271-2751678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5766/2870info:eu-repo/semantics/openAccess2014-08-15T17:22:02Zoai:ojs.seer.sct.embrapa.br:article/5766Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-15T17:22:02Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
