GENETIC DIVERGENCE IN PROGENIES OF A POPULATION OF Eucalyptus camadulensis DEHNH

ABSTRACT

The objective of this study was to recommend stock for hybridization, using analysis of variance and multivariate canonical covariance analysis to predict genetic divergence. Data from a test of 44 families of 67-month-old half-sibs of E. camaldulensis Dehnh. were used. Diameter at breast height (DBH), commercial height (ALTC), commercial volume without bark (VCSC), basic wood density (DBM), and trunk biomass without bark (BTSC) were evaluated. Genetic variation among families was observed for all traits analyzed. Canonical covariance analysis was efficient for demonstrating genetic divergence between the families studied and permitted the separation of the 44 families into 16 distinct groups.

Key words:
Eucalyptus camaldulensis, genetic divergence; forest breeding
