Inheritance and Correlation of Growth Characters in Hybrid Poplar Cones
Selection at the earliest possible age, the age at which the genetic potential of a tree or clone can be effectively determined, would be desirable to minimize costs in time, space, and labor. Shortening a test rotation by early selection of clones that will be of superior height and diameter at the end of a full rotation implies a strong relationship between size at maturity and earlier ages. This is a report on phenotypic and genetic correlations between height and diameter measurements made over time for hybrid poplars grown in a replicated clonal test for 15 growing seasons.
