Resumo: | Twenty one provenances of Grevillea robusta Cunn were tested at Nova Esperança and Quedas do Iguaçu, Paraná state and Anhembi, São Paulo state, Brazil. With the aim of comparing the performance of the original provenances with the comercial provenance collected in Maringa, Paraná state included as a control. Provenance trials were installed in a randomized block design with rectangular plots, each one with six plants spaced 3 m x 3 m, with 15 replications. Five among the ten best provenances at Anhembi presented better growth at Quedas do Iguaçu and Nova Esperança (Duck Creek, Fine Flower, Rappville, Bottle Creek and Mc Pherson’s Creek). Different environments did not interfere significantly in the average growth among different provenances indicating that the seeds of one region can be interchanged with the seeds of another region, where the provenances were tested, with no loss in productivity of wood. It was also concluded that the best provenances at Quedas do Iguaçu, Nova Esperança and Anhembi were originally collected in New South Wales state, Austrália.
