    Description

    Variation in budbreak date among 37 half-sib families of white spruce in a replicated one-parent progeny test plantation in southern Maine was only 5 days. Differences in the mean date of budbreak between years were greater than those between families, but the genetic correlation between date of budbreak in different years was .661. Heritability estimates ranged from .228 to .814, depending on the year and method of calculation. In each of 2 years, heritabilities estimated for family selection were higher than those for mass selection of indilvidual trees in the plantation, but family selection for late budbreak would result in genetic gains of less than 1.5 days if more than the two latest families were selected. Selections for late budbreak and rapid early height growth were not compatible; genetic correlations between date of budbreak and height elongation for the same year were large and negative.
