Performance in freezing tests and field experiments of full-sib families of Pinussylvestris (L.)
Full-sib families from plus trees of Pinussylvestris (L.) were tested in four 10-year field experiments and three 1-year experiments. Survival and height were assessed in the field experiments and plant height, dry matter content, and damage following artificial freeze testing during the hardening p...

Full-sib families from plus trees of Pinussylvestris (L.) were tested in four 10-year field experiments and three 1-year experiments. Survival and height were assessed in the field experiments and plant height, dry matter content, and damage following artificial freeze testing during the hardening process in the 1-year experiments. Positive correlations between pairs of field experiments were found for breeding values for 10-year survival (r mean = +0.71) and 10-year height (r mean = +0.38). Positive correlations were also obtained between survival and height within field experiments. Breeding values for 10-year field survival and height were not correlated with the latitude of origin.
