Resumo: The magnitute of the experimental error has a direct effect on the success of plant breeding experiments. This study aimed at evaluating the interference of stand correction methods on the yield of 25 grain sorghum hybrids, in seven environments. The methods tested were: without correction, rule of three, covariance of medium and ideal stand, Zuber, Cruz, Vencovsky & Cruz and stratified correction, based on genotype groups. The Pearson correlation coefficient was used to assess the magnitude of the influence exerted by each method, concerning the data without correction. The stand correction methods based on covariance and Vencovsky & Cruz reduced the coefficient of variation and showed a high correlation with the adaptability and stability parameters of hybrids, however, these differences were not so significant to justify such adjustment.

Este trabalho objetivou verificar a interferência de métodos de correção de estande na produtividade de 25 híbridos de sorgo granífero, em sete ambientes. Os métodos avaliados foram: sem correção, regra de três, covariância de estande médio e de estande ideal, Zuber, Cruz, Vencovsky & Cruz e correção estratificada, com base no agrupamento de genótipos. O coeficiente de correlação de Pearson foi utilizado para verificar a magnitude da influência de cada método, em relação aos dados sem correção. Os métodos de correção de estande baseados em covariância e de Vencovsky & Cruz reduziram o coeficiente de variação e apresentaram alta correlação com parâmetros de adaptabilidade e estabilidade dos híbridos, no entanto, estas diferenças não foram expressivas a ponto de justificarem a correção.Escola de Agronomia - Universidade Federal de Goiás2014-07-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimental; Métodos Quantitativosapplication/pdfhttps://revistas.ufg.br/pat/article/view/25696Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 44, n. 2, Apr./Jun. 2014; 175-181Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 44, n. 2, abr./jun. 2014; 175-181Pesquisa Agropecuária Tropical; v. 44, n. 2, abr./jun. 2014; 175-1811983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/25696/16772Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSilva, Karla Jorge daMenezes, Cicero Beserra deTardin, Flávio DessauneSouza, Vander FillipeSantos, Crislene Vieira2020-07-10T16:19:02Zoai:ojs.revistas.ufg.br:article/25696Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:03.525742Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
