Objectives:
-
To Compare the performance of controlled crosses vs. open pollinated progenies.
-
To estimate heritabilities based on one parent component.
-
To compare types of crosses (within and among selection units).
-
To provide information for design of future full-sib progeny trials.
-
To compare reciprocal plantings.
Experimental Design
Treatments:
Twenty-five full-sib crosses and five open pollinated families from the higher
ranking families of the Prince George selections are being tested. Seedlings
were grown at the Kalamalka Forestry Centre.
Layout
-
Each site contains 5 blocks.
-
A row of 4 seedlings represents one cross.
-
Crosses and open pollinated families are randomized within each block.
-
The first seedling of each row is marked with a wooden stake bearing a metal
tag identifying the block and the cross family.
History:
-
1982 plantation establishment and initial height measurements.
-
1984 3-year height measurements and maintenance.
-
1987 6-year height measurements and maintenance.
-
1991 10-year height measurements and maintenance
