Genetic Variation in Survival of Longleaf Pine

Open pollinated progenies of approximately 300 longleaf pines were established in 8 tests across Florida, Georgia and Alabama. Family heritability of survival one year after establishment was 0.35 for bare-root planted seedlings. Phenotypic variance included a large environmental component from the various nurseries, planting crews, and site factors affecting survival. Heritability of survival of tubelings was lower (0.24). For families planted both as bare-root seedlings and as tubelings, the GxE interaction was low but random error was high. Somewhat different genetic and environmental factors may affect survival of the two seedling types. Additional keywords: Pinus palustris, genotype x environment interaction.
