Abstract
Analysis of height growth from clonal and progeny trials from Soporcel 's Eucalyptus globulus breeding program gave regional heritabilities o f 0.28 +/- 0.03 and 0.19 +/- 0.04 for the north-west and south of Port ugal, respectively. Results also showed that cloning the parents used in the crossing program, even when based on a few ramets per clone, im proved considerably the accuracy of genetic parameter estimates and ef ficiency of backward selections. The benefits of cloning the parents f or selection efficiency seem justifiable even when large scale vegetat ive propagation is not feasible.
