Genetic, Spacing, and Genotype x Spacing Influences on Growth of Eucalyptus Grandis in South Florida

Thirty-three E. grandis progenies in three studies and a related spacing study were used to document genetic, spacing, and genotype x spacing factors for growth up to 2.5 years. Variation among progenies was substantial for total height, diameter, tree volume, and volume/ha. Although progeny comparisons across studies were inconsistent, similarities within studies between traits over ages suggest that early progeny assessment may be possible. Spacing can be modified to alter juvenile yields dramatically, while use of the better progenies, due to the lack of spacing x progeny interaction, will permit yield increases for different cultural systems. Additional keywords: Biomass, competition, genotype x environment interaction, early progeny assessment, selection.
