ABSTRACT
A progeny test of grevilea (Grevillea robusta A. Cunn), was evaluated for estimate the genetic parameters and the gains through selection for high plants, since first to the fourth year of plantation age. It was detected significant differences between progenies and the heritability estimated revealed moderate genetic control for the character and, possibilities of considerable gains with the selection among and within families. There were variations along the years in the estimates, except for the averages and variances. It was not observed the stabilization in the values of the parameters, being suggested the continuity of the experimentation by more time, for safe inference.
Key words:
Grevillea robusta; genetic parameters; genetic improvement
