Forestry's Third Revolution: Integrating Biotechnology into Pinus taeda L. Breeding Programs

Abstract

Abstract The Third Revolution—the application of molecular biology to plant improvement—is providing biotechnology for Pinus taeda breeding programs in the southern United States. To harness commercial value, forest biotechnology must be integrated with pine breeding. Overlaying an agriculture biotechnology template on any aspect of forestry ignores key historical, economic and biological factors unique to pine breeding programs and even to biotechnology applications. Understanding differences between forestry and agriculture will aid policy decisions about the use of genetically enhanced pines and identify numerous leverage points for directing forest biotechnology research toward commercial advantage. Integrating biotechnology into a P. taeda breeding program is illustrated using a case study approach. A molecular marker system is proposed for improving the selection efficacy of a pine breeding program. South. J. Appl. For. 25(3):116–121.
