Abstract

The nursery phase of the study started in 1971 to verify the genetic superiority of phenotypically superior trees of white spruce (Picea glauca (Moench)Voss)from two locations in central Newfoundland, Canada, was completed in 1975. Although statistically significant differences in four-year growth between the two locations were detected there were no such differences between the progenies of "plus" and "ordinary" trees at either location. The superiority of "plus" trees over "ordinary" trees may be due to more out-breeding in the former than in the latter class of trees. Heritability show the possibility of more genetic gain by selection from "plus" trees than that from "ordinary" trees. Establishment of a seed orchard of "plus" trees from each location is recommended.
