At first wood predictors for TMP potential are identified through the refining of thirty trees 17-year-old using a specific procedure on a 12 Andritz refiner. The variations of TMP physical properties are linked with those of anatomical parameters but also with within ring density related traits. The brightness of the unbleached TMP is negatively correlated with the red chromatic component of wood. Lignin holocellulose and extractives content on one hand Kraft fibre morphology on the other hand are considered to evaluate roughly the wood potential for the Kraft process. Then 15 clones out of 200 are non destructively selected within a 24-year-old German test to evaluate the range of the genetic variation of the papermaking potential. Chemical analyses give evidence of large variations of the chemical composition ratio between .
