Improvements in Stem Form and Growth of Elite Genotypes in Loblolly Pine

The Lower Gulf Elite population was a joint effort between the North Carolina State UniversityCooperative Tree Improvement Program, the Western Gulf Forest Tree Improvement Program, and the Cooperative Forest Genetics Research Project formed in the mid 1990’s with elite material from the Atlantic Coastal Plain, Florida, and Livingston Parrish/East Texas provenances. At the time it was created, this was the most elite material from these provenances considered to be suitable for the development of a land race for the lower Gulf Coastal Plain of the United States. This combination of provenances provided an excellent population to quantify the variation in growth and sawtimber quality in loblolly pine. The objectives for this research effort were to 1) estimate genetic parameters for age 6 year growth and stem form traits and 2) determine potential gains in sawtimber quality by family selection.
