| 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... |
