Resumo: | The objectives of this work were: to determine the resistance/susceptibility pattern of 20 elite oat genotypes to 40 isolates of Puccinia coronata f. sp. avenae; to determine the pattern of virulence/avirulence of isolates collected in three counties of Rio Grande do Sul to the oat genotypes studied; and to indicate potential parents for the generation of populations with high crown rust resistance. The resistance pattern of oat genotypes and the virulence/avirulence of the fungi were determined by the analysis of the reaction incited by the inoculation of Puccinia coronata f. sp. avenae isolates into seedlings of oat genotypes. The selection of genitors was based on the cultivar complementation index proposed in this work. Genotypes expressing resistance to the larger number of isolates were FAPA6, URS20, UPFA20, CFT1 and FAPA5, while UFRGS15, UPF15, UPF18, UPF19 and UPF16 were susceptible to a higher number of isolates. The following crosses are indicated: FAPA6 x Albasul, URS22 x FAPA6, CFT1 x URPEL15 and CFT1 x UFRGS19. |

Os padrões de resistência de Puccinia coronata f. sp. avenae e o de virulência/avirulência dos isolados foram determinados pela avaliação da reação desencadeada pela aspersão dos isolados deste fungo em plântulas de genótipos de aveia. A seleção de genitores foi baseada no índice de complementação de cultivares, proposto neste trabalho. Os genótipos que expressaram resistência ao maior número de isolados foram FAPA6, URS20, UPFA20, CFT1 e FAPA5, ao passo que os genótipos UFRGS15, UPF15, UPF18, UPF19 e UPF16 evidenciaram suscetibilidade ao maior número de isolados. Os cruzamentos mais indicados entre os genótipos estudados são: FAPA6 x Albasul, URS22 x FAPA6, CFT1 x URPEL15 e CFT1 x UFRGS19.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraVieira, Eduardo AlanoCarvalho, Fernando Irajá Félix deChaves, Márcia SoaresOliveira, Antonio Costa deBertan, IvandroMartins, Andreza FigueirolaHartwig, IrineuBenin, GiovaniValério, Igor PirezFonseca, Daniel Andrei Robe2006-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7181Pesquisa Agropecuaria Brasileira; v.41, n.4, abr. 2006; 607-614Pesquisa Agropecuária Brasileira; v.41, n.4, abr. 2006; 607-6141678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7181/4226info:eu-repo/semantics/openAccess2014-09-26T18:44:23Zoai:ojs.seer.sct.embrapa.br:article/7181Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T18:44:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
