Description

We genotyped parents and progeny of pin oak at two maternally-inherited and thirteen biparentally-inherited loci to determine whether hybrid vigor may be the cause of the recent rapid proliferation of pin oak on the Colby College campus. We found that the oldest planting was responsible for most progeny, but these progeny arose only after a second planting, suggesting hybrid vigor as a trigger of successful colonization. Parent plants were inbred but progeny were less so, supporting our hypothesis.
