Multivariate restricted maximum likeihood estimation of genetic parameters for diameter at 3 to 5 years in the Eucalyptus globulus base population in Australia

Abstract

Genetic parameters for diameter growth at three to five years in Victoria (four sites), Tasmania (five sites), South Ausbalia (one sites) and Western Australia (four sites) were estimated for the Eucalyptw glob&w Labill. ssp. globuluc base population using a derivative-free resuicted maximum likelihood (DFREhlL) procedure applied to a multirait individual tree model with diameter in each state used as a different trait. Within state heritabilitics ranged between 0.19 and 0.27. Genetic correlations between diameter growth in different states were always above 0.62 suggesting a reduced genotype-environment interaction.
