    Description

    Genetic and environmental components of variance for 2-year pot and nursery heights of offspring from inter- and intraprovenance matings in Scotch pine were studied to determine which provenances and selection methods should be used in an ornamental and Christmas tree improvement program. Nursery evaluation was preferred to pot evaluation because heritability estimates were larger and error variances were smaller for the experiments evaluated. Simple recurrent selection would be a good method for improving traits important to the Christmas tree industry.
