interfamily variation in wood quality of black spruce in a northwestern ontario progeny trial
abstract
the right trees for replanting must be selected to ensure optimal future forest conditions.
based on desired future outcomes, various progenies can be selected to suit these needs. in
canada, black spruce (picea mariana), plays a crucial role in the forest economy. this is due to
the large range the species covers as well as the variety of products produced from it, especially
pulp. it is hypothesized that various families differ significantly in wood quality. top growing
families (designated with high breeding values) are believed to have the poorest wood quality
due to their rapid growth. this paper aims to test that hypothesis and examine the correlation
between breeding values and wood quality. samples tested through models such as regressions
and anova analysis concluded that there is low to none statistical significance between wood
quality and breeding value. however, this result could possibly be attributed to a low number of
samples, as well as lack of control for block effects.
