Resumo: In Brazil the rust caused by Puccinia psidii Winter stands out as the most important disease of eucalyptus. The use of resistant genotypes is the main control method, which makes the detection of markers linked to rust resistance essential to the selection of resistant genotypes. In this study, an F1 progeny of 131 plants from interspecific crossings of Eucalyptus was used to identify markers linked to resistance genes for this pathogen. An integrated map was constructed for linkage group three based on microsatellite markers. For QTL mapping two methodologies based on alleles identical-by-descent (IBD) were used: single marker analysis of Haseman and Elston and the interval mapping procedure of Fulker and Cardon. Both methods showed significant association for the Embra 125 marker.The QTL that explained 42 % of the phenotypic variation was mapped to 0.02 cM of this marker by the Fulker and Cardon. Marker Embra 125 has potential use in assisted selection, thus increasing the efficiency of the selection of resistant genotypes.

O uso de genótipos resistentes é o principal método de controle, o que torna a detecção de marcadores ligados a resistência à ferrugem essencial para a seleção de genótipos resistentes. Neste estudo, uma progênie F1 composta por 131 plantas derivadas de um cruzamento interespecífico de Eucalyptus.Um mapa integrado foi construído para o grupo de ligação três com base em marcadores microssatélites. Para detecção de QTL foram utilizadas duas metodologias baseadas em alelos idênticos por descendência (IBD): marca simples de Haseman and Elston e mapeamento por intervalo de Fulker and Cardon. Ambas as metodologias evidenciaram associação mais significativa para o marcador Embra 125. O QTL que explicou 42 % da variação fenotípica foi mapeado a 0,02 cM desse marcador pela metodologia de intervalo de Fulker and Cardon. O marcador Embra125 têm potencial utilização em seleção assistida, com conseqüente aumento na eficiência durante a seleção de genótipos resistentes.Crop Breeding and Applied Biotechnology2019-08-26T11:51:35Z2019-08-26T11:51:35Z2010-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1984-7033http://dx.doi.org/10.1590/S1984-70332010000400006https://locus.ufv.br//handle/123456789/26659engv. 10, n. 04, p. 321- 328, dez. 2010Rosado, Tatiana BarbosaTomaz, Rafael SimõesRibeiro Junior, Marcio FernandesGuimarães, Lúcio Mauro da SilvaAraújo, Elza Fernandes deAlfenas, Acelino CoutoCruz, Cosme DamiãoRosado, Antônio Marcosinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T06:40:51Zoai:locus.ufv.br:123456789/26659Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:40:51LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
