Northwest Tree Improvement Cooperative (NWTIC)
Mission and Goals
The mission of NWTIC is to assist and coordinate members in developing
and managing their forest gene resources in the Pacific Northwest. Accordingly,
NWTIC is committed to the following goals:
Tree Improvement Process
The tree improvement and breeding strategies that have been developed
for each species are unique and have been tailored by such factors as:
reproductive biology and geographic distribution of the species, extent
of phenotypic and genotypic variation, availability of provenance test
data, extent of parent tree selections, and present and projected
planting requirements.
Genetic improvement of forest trees is best described by the tree
improvement cycle of selection, testing and breeding in which the genetic
quality of a species is improved, and the gains are delivered to the
field through gentically improved seed from seed orchards or as rooted
cuttings, if feasible. Tree improvement does take time - it may be 10
years before seed orchards begin to produce significant quantities of
improved seed for reforestation. Concurrent research is aimed at reducing
the time required to complete the cycle, and improving methods of selection,
testing and breeding.
