Genetic Variation in Blue Spruce
Author: David F. Van Haverbeke
Publisher:
ISBN:
Category : Spruce
Languages : en
Pages : 12
Book Description
Analyses of 43 blue spruce populations at age 12 (9 years in the field) revealed significant differences among populations for survival, height, vigor, crown diameter, frost injury, and foliage color. Use of regions increases the probability of locating better seeds sources, but high variability among individual populations within regions limits their value in specifying where better seed sources can be collected. Phenotypes should be selected in best stands within regions.
