Resumo: Nineteen Brazilian wheat varieties have been tested as to their yielding stability, through the linear regression method, using experimental data recorded at six Rio Grande do Sul localities, from 1975 to 1979. The regression coefficient analysis of grain yield in relation to the environment quality showed that the tested varieties, except IAS - 62, were adjusted to the middle regression and almost all of them reacted similarly to the environment variations. Most of the varieties have shown similar performance under variable environmental conditions, however some of them (IAS 55, IAS 58, IAS 61, Jacuí and Nobre) performed poorly as evidenced by significant regression deviations.

Analisando o coeficiente de regressão dos rendimentos de grãos em relação à qualidade do ambiente, verificou-se que as variedades testadas, com exceção de IAS 62, ajustaram-se à linha média de regressão, reagindo quase todas de forma semelhante ante às variações ambientais. Quanto à estabilidade de rendimentos, a maioria das variedades comportou-se como estável, exceto IAS 55, IAS 58, IAS 61, Jacuí e Nobre, que apresentaram desvios da regressão significativos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraOsorio, E.A.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16015Pesquisa Agropecuaria Brasileira; v.17, n.8, ago. 1982; 1141-1144Pesquisa Agropecuária Brasileira; v.17, n.8, ago. 1982; 1141-11441678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16015/10161info:eu-repo/semantics/openAccess2014-04-16T16:22:09Zoai:ojs.seer.sct.embrapa.br:article/16015Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T16:22:09Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
