Abstract
In 1972 a progeny trial with Picea sitchensis (BONG.) were established on 3 harsh locations in Denmark. Growth and qualitative parameters ha ve been measured several times. Growth, stem form, wood density (pilod yne), frost resistence and resistence to aphids were found to be partl y under genetic control, and the characters are mostly interrelated. T he age-age correlations for growth are high, and selection could be ca rried out with advantage before 10 years of age.High variation in grow th within site, high plant departure and aphid attacks were found in o ne of the trials. Substantial genotype by environment interaction for growth parameters was revealed between this trial and the 2 trials wit h lower mortality.
