Matching Loblolly Pine Families to Regeneration Sites
Abstract:The family block system has several advantages that make it a desirable method for deploying genetically improved loblolly pine (Pinus taeda L.). Orchard and nursery productivity can be improved with family block management, and families can be matched to sites. Soil properties and productivity levels are criteria that should be used by foresters to decide where available families should best be planted. The appropriate strategy for matching individual families to sites is dependent on (1) the magnitude of genotype by environmental (G x E) interaction within the applicable breeding region, and (2) the identification of causal site factors. Given the absence of substantial family rank change, shorter orchard service life, and the high cost of edaphic screening, foresters are advised to plant the best half-sib families on the best sites.
