Resumo: To determine the phenotypic variability for traits of oat panicle among the varieties grown in the southern Brazil, with and without application of fungicide. The experiment was done at the Experiment Station of UFRGS, in Eldorado do Sul, Brazil. Each plot had four lines of 5m of length, spaced 0,20m, with three replications without fungicide, and three replications with apllication of propiconazole 0,5 l/ha. Five panicles per plot where collected before harvest and panicle weight, number of flowers/panicle, number of grains/panicle, fertility, and grain weight, were determined. Grain yield was obtained by harvesting two central rows of each plot. Great phenotypic variability was observed for all traits with and without fungicide application. Varieties with higher grain yield revelated different values for the traits analised. These results indicate that different combinations of traits may produce high grain yield and different oat plant ideotype can be adequate for the environments of the southern Brazil.

O experimento foi realizado no campo, e cada parcela foi constituída de quatro linhas de 5m de comprimento com espaços, entre si, de 0,20m. Foram coletadas cinco panículas de cada parcela e determinado o peso da panícula (PP), número de flores/panícula (NF), número de grãos/panícula (NG), fertilidade (FF) e peso de grãos/panícula (PG). O rendimento de grãos (RG) foi obtido pela colheita das duas linhas centrais da parcela. Grande variabilidade fenotípica foi observada relativamente a todos os caracteres, com e sem aplicação de fungicida. As variedades com maiores rendimentos de grãos revelam diferentes valores quanto aos caracteres avaliados, o que indica que genótipos superiores podem ser obtidos por diferentes combinações de caracteres e que diferentes tipos ideais de planta podem ser definidos na Região Sul do Brasil.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFederizzi, Luiz CarlosAcauan, Laurenço Rolimde Carvalho, Fernando Irajá FelixBodanese-Zanettini, Maria Helena1995-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4296Pesquisa Agropecuaria Brasileira; v.30, n.2, fev. 1995; 223-229Pesquisa Agropecuária Brasileira; v.30, n.2, fev. 1995; 223-2291678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4296/1582info:eu-repo/semantics/openAccess2010-05-03T18:37:18Zoai:ojs.seer.sct.embrapa.br:article/4296Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-05-03T18:37:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
