Resumo: Full-sib progenies were evaluated with the objective of comparing the performance of selected individuals in progenies tests with their clones in clonal tests. The experiments were carried out in randomized complete block design with five replications, five plants per plot, spaced at 3 m x 3 m, and four controls. The wood volume of each tree was determined after four years of growth. The 173 selected trees in the progeny test were used in the clonal tests in two different locations. The same experimental design was used with 20 replications, one tree plot, spaced at 3.5 m x 2.15 m with a border, and 13 controls (commercial clones). The growth traits of each tree were determined after two years of planting. Genetic parameters were estimated using general linear models. Realized heritability was greater than 80% indicating that the selection of trees in the progeny test was efficient.

Os experimentos foram implantados em blocos completos casualizados com cinco repetições e cinco plantas por parcela, no espaçamento de 3 x 3 m e quatro testemunhas. O volume de madeira de cada árvore foi avaliado no segundo e quatro anos. As 173 árvores selecionadas no teste de progênies foram avaliadas em testes clonais em dois diferentes locais. O mesmo delineamento experimental foi utilizado, porém com 20 repetições e parcelas de uma planta, no espaçamento de 3,5 x 2,15 m e 13 clones comerciais como testemunhas. Os caracteres de crescimento de cada árvore foram determinados no segundo ano de campo. Parâmetros genéticos foram estimados usando modelos lineares generalizados. A herdabilidade realizada foi superior a 80%, indicando que a seleção de árvores no teste de progênies foi eficiente.Associação Brasileira de Melhoramento de Plantas2013-11-07T17:22:42Z2013-11-07T17:22:42Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFONSECA, R.
