Age-Five Results from the Cooperative Forest Genetics Research Program Slash Pine Polymix Trials
(2003)The Cooperative Forest Genetics Research Program (CFGRP) has completed polymix test installation for the second generation of slash pine (White, et al. 1993).The objective of this testing is to evaluate the general combining ... -
Antibiotics Effects on the Elimination of Agrobacterium tumefaciens from Loblolly Pine (Pinus taeda L.) Zygotic Embryo Explants and on Transgenic Plant Regeneration
(2003)Three antibiotics were evaluated for their effects on the elimination of Agrobacterium tumefaciens during the genetic transformation of loblolly pine (Pinus taeda L.) using mature zygotic embryos as targets. Agrobacterium ... -
Characterization of a Bacterial Contaminant in Loblolly Pine Tissue Culture
(2003)Bacterial contamination of immature seed explants can decrease the efficiency in initiating and establishing pine embryogenic cultures. A type of contaminant commonly observed surrounding the megagametophyte explant of ... -
Complementary Pairs Interaction of Resistance Genes and Avirulent Genes in Loblolly Pine: Fusiform Rust Pathosystem Using Diallel Data
(2003)Loblolly pine (Pinus taeda L.) seedlings from 12 full-sib families were obtained from a 6-parent half diallel mating design. These seedlings were challenged using two inocula of the fusiforn rust fungus( Cronartium quercuum ... -
Cone and Seed Insect Pest Research: The Role of the Southwide Studies
(2003)A reliable supply of genetically improved pine seed is critical to the success of production forestry. The most significant environmental threat to the ability to meet this demand (over 100,000 pounds per year) is insect ... -
Conservation Efforts for Pinus maximinoi in Mesoamerica and Its Potential as a Hybrid with Pinus taeda in South America
(2003)Seed samples were collected from 25 populations of Pinus maximinoi from Guerrero, Mexico to central Nicaragua and established in provenance tests in Brazil, Colombia and South Africa by the CAMCORE Cooperative. The trials ... -
Cooperative Second-Generation Breeding and Testing of Coastal Douglas-fir in the US Pacific Northwest
(2003)Forest tree improvement got underway in the Pacific Northwest of the USA in the 1950s. Graft incompatibility became evident by the early 1960s and dampened enthusiasm for grafted clonal orchards for this species A different ... -
Development of Differential Screening Panels for Slash Pine-Fusiform Rust Reaction Types
(2003)Understanding the genetic basis for disease resistance is crucial to ensure a successful breeding and deployment strategy for slash pine. A complementary genetic interaction model has been hypothesized for the pine-fusiform ... -
Early Performance and Genetic Parameters for Atlantic Coastal and Piedmont Loblolly Pine and Their Hybrids in the Piedmont
(2003)Atlantic Coastal (C) and Piedmont (P) loblolly pine (Pinus taeda L.) sources and their hybrids were assessed at four years of age for height and survival in 15 test sites across five Piedmont regions (Piedmont, Upper Gulf, ... -
Efficacy of Breeding for Brown Spot Disease Resistance in Longleaf Pine
(2003)The study objective was to determine whether selection for brown spot disease (caused by Scirrhia acicola (Dearn.) Siggers) resistance in longleaf pine (Pinus palustris Mill.) is beneficial for areas where brown spot is ... -
Evaluation of an Open-Nucleus Model for Forest Tree Breeding
(2003)Open-nucleus breeding was evaluated by stochastic simulation. Methodology was developed for unrestricted migration rate between two tiers (main and elite). Genetic progress in the breeding population was iteratively maximized ... -
Evaluation of Height as an Early Selection Criterion for Volume and Predictor of Site Index Gain in the Western Gulf
(2003)Data from repeated periodic measures of height, diameter and volume from eleven loblolly pine progeny tests maintained as part of the Western Gulf Forest Tree Improvement Program (WGFTIP) were analyzed to 1) determine the ... -
Evaluation of the Inheritance of Tip Moth Susceptibility Using Pine Hybrids Planted in Southeast Mississippi
(2003)Nineteen families of susceptible and resistant pine parent species and their interspecific hybrid progenies were quantitatively assessed for Nantucket pine tip moth (Rhyacionia frustrana Comstock) damage in a study in ... -
Field Performance of Shortleaf Pine Half-Sib Families Though 10 Years in the Ouachita Mountains of Arkansas
(2003)Shortleaf pine (Pinus echinata Mill.) seeds collected from six half-sib families were grown as both bareroot and container stock and outplanted on two sites in the Ouachita Mountains of Arkansas. Survival and growth were ... -
Field Selection of American Sweetgum Transformed for Herbicide Resistance
(2003)One American sweetgum clone from an open-pollinated parent was transformed with Agrobacterium tumefaciens containing the gene for acetolactate synthase (ALS), and regenerated through organogenesis. Seventy independently ... -
Fourth-Year Results from a Clonal Test of Loblolly Pine
(2003)In November and December 1998, two experimental plantings were established using rooted cuttings from 450 clones of eight unrelated full-sib families of loblolly pine (Pinus taeda L.). Clones from four of the families (282 ... -
Functional Genomics Pipeline in Loblolly Pine and Eastern Cottonwood
(2003)Advances in transformation technology allow functional genomics techniques that are commonly applied to Arabidopsis thaliana to be considered for tree species. ArborGen is applying the principles of high throughput functional ...
