Strong, independent, quantitative genetic control of the timing of vegetative phase change and first flowering in eucalyptus globulus ssp. globulus (Tasmanian blue gum)

摘要: Analyses of large open-pollinated and controlled-cross field trials Eucalyptus globulus ssp. show quantitative genetic independence the times first flowering abrupt change in leaf form. The onset each these critical developmental events is under moderate to strong additive control this taxon, with individual narrow-sense heritabilities 0.4–0.6 0.2–0.9, respectively, little nonadditive control. This processes provide environment for rapid heterochronic microevolution.
