Abstract
Intensity of needle coloration for inbred seedlings of Picea pungens Engelm. (blue spruce) increased with seedling age. Needle color ratings for 7- and 10-year-old, inbred seedlings and parental trees were correlated. Mean heights of the 10-year-old, inbred progenies ranged from 50 to 76 cm, but bore no relationship to parental selffertility or needle color. In one selection, 94% of the inbred seedlings had silvery-blue foliage.Keywords
