Resumo: | A provenance/progenies trial of grevílea (Grevillea robusta Cunn.) was established in the Ponta Grossa region, state of Paraná, Brazil. The purpose was to identify genetically superior individuals in order to assure good material for future seed orchard. The genetic matherial was based on 60 half-sib progenies from eighteen Australian provenances and one control. Progenies were evaluated in randomized blocks with seven replications, five plants per plot and spacing of 3 m x 3 m (9 m2 per plant). Significant gains were estimated through selection of the 200 best trees (23,33%), for cilindric volume, at 10 years age, based on genetic values, aiming to establish a seedling seed orchard; or selecting the best twenty trees (33,33%), towards a clonal seed orchard. |

O material genético consistiu de 60 progênies de meios-irmãos provenientes de dezoito procedências australianas e de uma testemunha comercial. O delineamento experimental foi o de blocos ao acaso com oito repetições de cinco plantas por parcela, no espaçamento de 3 m x 3 m (9 m2 por planta). Obteve-se ganhos significativos para o volume cilíndrico, aos 10 anos de idade, em relação à testemunha comercial, com a seleção das 200 melhores árvores (23,33%), com base em seus valores genéticos, com o propósito de se instalar um pomar de sementes por mudas, ou com a seleção das 50 melhores árvores (33,33%), com o intuito de propagá-las para um pomar de sementes clonal.Embrapa Florestas2004-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1594Pesquisa Florestal Brasileira; n. 48 (2004): jan./jun.; 29-39Pesquisa Florestal Brasileira; No. 48 (2004): jan./jun.; 29-391983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1594/647Martins, Emerson GonçalvesSturion, José AlfredoNeves, Edinelson Jsosé Macielinfo:eu-repo/semantics/openAccess2018-03-22T17:55:25Zoai:pfb.cnpf.embrapa.br/pfb:article/1594Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-03-22T17:55:25Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
