EARLY GENETIC EVALUATION METHODS FOR CYCLIC GROWTH IN PINUS-TAEDA L

The seedling growth trait, cyclic growth, is well-correlated with olde r-tree heights measured in Pinus taeda L. field trials. These results have been repeatable across locations and seed sources if a standard g reenhouse procedure is followed. This work is been limited to cyclic g rowth measured on P. taeda families and seed sources. The use of a sta ndard greenhouse procedure will facilitate-comparison with other early genetic evaluation methods for P. taeda and with similar studies on o ther Pinus species.
