Title: Performance of Loblolly Pine Seed Sources in Argentina

Author: La Farge, Timothy; Bridgwater, Floyd E.; Baez, Mirta N.;

Date: 1999

Source: Proceedings of the 25th Biennial Southern Forest Tree Improvement Conference, New Orleans, Louisiana, USA

Publication Series: Miscellaneous Publication

Description: Four test series of loblolly pine (Pinus taeda L.) were evaluated to determine the performance in northeastern Argentina of seed sources from three breeding populations in the southeastern United States. Three half-sib progeny tests of seed sources from Florida and Louisiana demonstrated strong genetic gains for height, dbh, and volume growth. However, full-sib progeny tests in three test series of seed sources from Texas, Louisiana and Mississippi performed poorer than checklots from land races in Argentina. To build a greater genetic base of loblolly pine for Argentina it would be better to sample other seed sources from the southeastern USA.

Keywords: seed source, land race, progeny test, checklot.
