Abstract: Eight provenances and 190 open pollinated families of Eucalyptus urophylla were studied at ages of 1,1.5,2 and 3.5 years.There were significant differences among provenances in volume and among families in height, DBH and volume.The variations of growth characters are moderately inheritable.Based on the results of age to age genotypic and phenotypic correlations,the early selection for E. urophylla can be implemented at the age of 2 years.Superior provenances and families were selected on the basis of performance level.Selection results were also presented in this paper.
