Abstract:

The USDA Forest Service Resistance Screening Center processes hundreds of slash and loblolly pine seedlots each year to assess relative resistance to fusiform rust. This greenhouse screening method provides quick, reliable screening under controlled conditions. Progeny tests can provide this information, but at a greater cost and longer assessment time. Furthermore, infection is not assured under field conditions. Several studies in the past have documented the efficacy of superior stock genotypes (Zobel, 1977, Porterfield, 1973). The goal of this economic analysis was to determine the economic benefits of using the Resistance Screening Center to screen for superior, resistant stock. Benefits for this study were based on a reduction in timber mortality and seedlings required for planting. The incremental benefit cost ratio for returns after taxes for the commercial production of timber was estimated at 2.7:1, over that of an investment in nonresistant, superior trees.
