Abstract

Assessing the risk of pollen-mediated gene flow from planted forests requires biological information on the translocated species, and tools for hybrid identification. The timing of peak anthesis in translocated trees was stable over years suggesting strong genetic control of anthesis time. Near infrared reflectance spectroscopy resolved F1 hybrids better than morphology with assignment accuracy of 72 to 100% and 60 to 76%, respectively. Advanced generation hybrids had greater resolution than F1 hybrids using NIR with up to 100% accuracy while morphology provided lower resolution (33%). The information provided can be used to assess and manage gene flow from planted forests.
