Progeny of presumed natural hybrids of shortleaf (P. echinata Mill.) and loblolly pine (P. taeda L.) growing in the Piedmont of South Carolina were found to have height and diameter growth rates between those of the 2 species. Survival of these trees was less than loblolly but no differences were found between them and shortleaf pine. Incidence of fusiform rust was low, with the putative hybrid having an infection rate 3-11% lower than loblolly pine. These putative hybrids, perhaps natural hybrids of loblolly and shortleaf pines, also offer potential resistance to littleaf disease [caused by Phytophthora cinnamomi] and would be a planting alternative to shortleaf pine in certain areas.
