Description: A progeny test of 226 superior tree selections from nine geographic sources across the South confirmed earlier results that showed the Gulf Coast source superior in survival and growth. Family variation within a region was large and provided additional genetic gain. Control-pollinated tests of elite x elite trees yielded even more gains. Progeny of the elite x elite crosses had higher survival, less brown-spot infection, and greater wood volume than progeny from crosses involving only one or no elite parent.

Keywords: Pinus palustris, geographic variation, progeny test, survival, growth, brown-spot needle blight
