The future

  • Sonic tools should make it cost effective to

assess progenies of elite parents establish real breeding values for predicted stiffness

  • Strategically plan crossing programs for future

series of clonal tests and synthetic hybrid breeding to actively breed for juvenile wood quality

Produce a pool of elite, superior, first class,

top-shelf clones very profitable primary production for Queensland (…. and other deployment possibilities?)
