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 ... -
Transgenic Loblolly Pine Trees from Diverse Elite Families
(2003)Loblolly pine (Pinus taeda L.) has been the focus of genetic improvement for nearly 100 years because of the value of this species to the forestry industry. The application of gene transfer technology to loblolly pine ... -
High Efficiency Transformation of Loblolly Pine (Pinus taeda L.) Using Green Fluorescent Protein as a Vital Screenable Marker
(2003)An engineered green fluorescent protein (m-gfp5-ER) gene under the control of the 35S Cauliflower Mosaic Virus promoter was used to develop a facile and rapid loblolly pine (Pinus taeda L.) transformation system via ... -
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 ... -
New Model for Moving Forward with Marker-based Selection
(2003)Increasing the frequency of favorable alleles in populations is the goal of tree breeding based on an additive genetic model. Conceptually, marker based selection (MBS) combined with accelerated breeding offers a more ... -
Use of Site Factor Studies in Determining Environmental Variables That May be Important for Genotype by Environment Interaction
(2003)The environmental variables important in determining genotype x environment interaction with Pinus patula in Southern Africa were investigated using a �site factor study� approach. Several previous such studies with P. ... -
Performance of Nuttall Oak (Quercus texana Buckl.) Provenances in the Western Gulf Region
(2003)Three series of three tests each of Nuttall oak (Quercus texana Buckl. formally Q. nuttallii Palmer) were established by the Western Gulf Forest Tree Improvement Program at three locations: Desha and Lonoke Counties in ... -
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 ... -
TREEPLAN� - A Genetic Evaluation System for Forest Trees
(2003)The TREEPLAN� genetic evaluation system is designed specifically for the efficient and accurate prediction of breeding and other genetic values in trees. TREEPLAN� uses the preferred statistical method of best linear ... -
Rooting Cuttings of Northern Red Oak (Quercus rubra L.)
(2003)Several techniques have been used experimentally to vegetatively propagate northern red oak (Quercus rubra L.), including: 1) rooting juvenile softwood cuttings in intermittent mist, 2) rooting shoots originating from ... -
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 ... -
On the Origin of Fusiform Rust Resistance in Loblolly Pine
(2003)Studies of geographic variation in loblolly pine (Pinus taeda L.) have shown that seed sources from the western (generally west of the Mississippi River) and the northeastern part of the natural distribution are relatively ... -
Genetic Analysis of a Disease Resistance Gene from Loblolly Pine
(2003)Rapid advances in molecular genetics provide great opportunities for studies of host defense mechanisms. Examination of plant responses to disease at the cellular and molecular level permits both discovery of changes in ... -
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 ... -
Time Trend and Genetic Difference of Rust Infection in a Diallel Loblolly Pine Population Across Four Tests
(2003)Loblolly pines from a six-parent half diallel mating were planted in a randomized complete block field design at four test sites. Fusiform rust infection (gall presence / absence) was recorded annually through age 8. A ...
