Resumo: | http://dx.doi.org/10.5902/1980509818465The aim of this study was i) to compare the results obtained with the Z index (sum of standardized variables) in relation to the classical (Smith, 1936; HAZEL, 1943) and rank sum indexes (Mulamba and MOCK, 1978) by means of the growth and wood technology traits and ii) to verify the progeny x environment interaction in simultaneous multiple trait selection, based on the Z index. Thus, we used a full sib progeny test of Eucalyptus urophylla and Eucalyptus grandis evaluated in two locations in the municipality of Ipaba, Minas Gerais state. At three years of age, the following traits were evaluated: average yearly increase of wood, wood density, refined pulp yield and effective alkali. There was good agreement in the progeny selection by the indexes. Thus, use of the Z index of standardized variables is a good option in simultaneous selection of multiple traits in the forestry sector through its ease of application and, above all, interpretation of results. The mentioned index revealed efficient in the study of the genotypes x environments interaction. |

Para isto, foi utilizado um teste de progênies de irmãos completos de Eucalyptus urophylla e Eucalyptus grandis avaliado em dois ambientes no município de Ipaba - MG. Aos três anos de idade, foram avaliadas as seguintes características: incremento médio anual de madeira, densidade básica da madeira, rendimento depurado de celulose e álcali efetivo. Houve boa concordância na seleção de progênies pelos índices. Assim, o emprego do somatório Z das variáveis padronizadas é uma boa opção na seleção simultânea de vários caracteres no setor florestal, pela facilidade de aplicação e, sobretudo, de interpretação dos resultados. O referido índice se mostrou eficiente no estudo da interação genótipos x ambientes.Universidade Federal de Santa Maria2015-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1846510.5902/1980509818465Ciência Florestal; Vol. 25 No. 2 (2015); 459-467Ciência Florestal; v. 25 n. 2 (2015); 459-4671980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/18465/pdfReis, Cristiane Aparecida FioravanteGonçalves, Flávia Maria AvelarRamalho, Magno Antonio PattoRosado, Antônio Marcosinfo:eu-repo/semantics/openAccess2018-09-12T13:36:30Zoai:ojs.pkp.sfu.ca:article/18465Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-09-12T13:36:30Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
