Resumo: The present study was carried out to estimate some genetic parameters and apply the principal components technique as a support for selection of several traits in erva-mate. Heritability estimates were significant for most of the evaluated traits suggesting possibility of great genetic gains with simple selection techniques. The shaft height trait showed high coefficient of variation, low heritability and low correlation with the other ones. Beside that, this trait showed to have the lowest contribution to the total variation of the data, as demonstrated by principal components, and could be discarded. Plant height and crown diameter, on the other hand, accounted for the most part of the detected variation.

Os resultados indicaram ser possível obter sucesso com a seleção para os caracteres avaliados, haja vistos que as herdabilidades foram de magnitude média a alta. O caracter altura do fuste foi o que apresentou maior coeficiente de variação, menor herdabilidade e menor coeficiente de correlação com os demais. Por meio dessa técnica, observou-se que a altura do fuste foi a que menos contribuiu para a variação dos dados, sendo passível de descarte. Verificou-se que os caracteres altura da planta e diâmetro da copa podem representar de maneira satisfatória a variação ocorrida.Universidade Federal de Santa Maria2002-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/169710.5902/198050981697Ciência Florestal; Vol. 12 No. 1 (2002); 21-27Ciência Florestal; v. 12 n. 1 (2002); 21-271980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1697/972Rosse, Leonardo NovaesFernandes, José Sebastião Cunhainfo:eu-repo/semantics/openAccess2017-06-05T14:13:13Zoai:ojs.pkp.sfu.ca:article/1697Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-05T14:13:13Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
