Other claims from this paper (10)
- Observation Growth traits of silver birch clones were mostly under strong genetic influence.
- Observation Silver birch clones had high potential genetic gain.
- Observation Survival did not appear to be a trait of genetic importance in these clone tests.
- Observation The genetic correlation between growth and growth cessation was weak.
- Observation Transfer effects for clones of different origin were not significant.
- Observation The genotype-by-environment interaction was weak.
- Recommendation Southern Sweden can be treated as a single utilization zone for these clone tests.
- Recommendation Few test sites are needed for genetic tests of these clones.
- Observation Genetic age-by-age correlations were strong.
- Recommendation Short test periods could be used in these genetic tests.
