Abstract

Genetic variation in the pulp qualities of Eucalyptus obliqua L'HĂ©rit.

Abstract

Samples were taken from trees grown in northern Tasmania from seed from 22 different provenances throughout the natural range of the species. Genetic differences were demonstrated between provenances for growth and pulp yield. Provenances which produced the fastest growing trees produced the strongest pulps and the highest yields of pulp. They were also cheaper to pulp owing to their reduced requirement for soda. Correlations suggest that selection between provenances for increased diam. growth would lead to increased pulp strength without the necessity for screening provenances for pulp strength. Further selection within provenances would still be necessary in order to determine suitable breeding parents.
