Tree breeding is basically aimed at producing quality products like seeds and clones and the most valuable contribution ofmolecular markers in breeding programs would be to reduce the time of selection or to reduce the number of breedingcycles. This can be achieved either by the early identification of superior progeny or by the identification of parents that willyield superior progeny. The present study highlights the use of microsatellite markers towards development of putativemarkers tagging the adventitious rooting trait in Eucalyptus tereticornis. Further, putative cellulose synthase specific markerswere identified and correlated with pulping character of wood tissues. The validation of these putative markers in largerpopulations can lead to more efficient and broadly applicable early selection procedure for key traits in eucalypt breedingprograms.
