T<span>he variance components, the heritability, the Speaman’s rank correlation and the coincidence indexes in the clone selection at the two models were estimated. </span>It was found that the augmented block design and the one way classification provide similar results in <em>Eucalyptus</em> clone evaluation. The coincidence indexes between the two models in the clone selection, in general, were high, showing values of 100% in the local combined analyses at 90 months. The Spearman’s rank </span></span></p>
