| 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. |

| Twenty and twenty three seed provenances of Grevillea robusta A. Cunn. were imported from Australia, in 1993 and 1994, respectively, by Embrapa Florestas. This genetic germoplasm was utilized for starting a breeding program in the states of Paraná, São Paulo and Mato Grosso do Sul. In 2002, twenty eight genotypes were selected in the Presidente Castelo Branco-PR district whose seeds were utilized for the installing second generation progenies test in Avaré-SP. Randomized blocks was the statistical design utilized, with linear plots of five plants, adjusted in a compass 3m x 3m, with 8 replications. Total height, DBH (diameter at the height of breast) were the characteristics considered in the volume evaluations. Estimation of variance components, genetic... |

| Twenty and twenty three seed provenances of Grevillea robusta Cunn were imported from Australia, in 1993 and 1994 respectively, by Embrapa Florestas. This genetic germoplasm was utilized for starting a breeding program in the State of Paraná, São Paulo and Mato Grosso do Sul. Total surface occupied by Grevillea experiments managed by Embrapa Florestas reachs 27,13 ha, being provenance tests, embracing 11,22 ha, installed in 1994, and progenies tests, comprising 15,91 ha, planted in 1994. In the Presidente Castelo Branco District it was introduced a provenance/progenie test with 104 progenies and 20 provenances. In 2001, it was selected the best genotypes and the experiment was transformed in a Seed Orchard. In 2002, 37 genotypes were selected at the same... |
