Fifth-year Performance of Progenies of Selected South African Slash and Loblolly Pine Clones

SYNOPSIS Control-pollinated polymix progenies of nine slash pine (P. elliottii Engelm.) and 10 loblolly (Pinus taeda L.) pine from some of the best clones in a South African tree improvement programme were tested in Georgia. Overall, the progenies of the South African selections in both species have done well after five years in the field. One of the slash pine and three of the loblolly pine families were better than open-pollinated progeny from established seed orchards.
