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.
