Eucalyptus nitens genetic parameters

摘要: Eucalyptus nitens (Deane et Maiden) Maiden is a significant plantation species in temperate regions of the world, with breeding occurring Australia, Chile, South Africa, and New Zealand. We reviewed published genetic parameters from over 100 field trials calculated average values for key growth, wood property, tree architecture, fitness traits. Parameter estimates control-pollinated progeny were rare. However, numerous parameter available open-pollinated several traits, such as diameter basic density, suggesting that this mating type our are likely to be robust. In trials, heritabilities growth traits (e.g., h 2 op= 0.26 diameter) generally lower than those property op = 0.51 density). trend was reversed additive coefficients variation CV a=13.3% 4.5% Inter-age correlations stem ranged 0.68 1.00 but not important cellulose content pulp yield).
