Performance Effects of Outside Pollen on Seed Orchards In and Out of the Genetic Source Area
(2003)Contamination by outside pollen sources is recognized as a serious problem that reduces the genetic gain obtained from open-pollinated seed orchards. A mitigating tactic is to locate an orchard outside the source area into ... -
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 ... -
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 ... -
Slash and Loblolly Pine Productivity on Reclaimed Titanium Mined Lands in Northeast Florida
(2003)Titanium mining often occurs on forestlands that previously supported productive pine plantations. The productivity of reclaimed mined lands is uncertain, based on observations that tree height on reclaimed lands is less, ... -
Validation of Predicted Breeding Values for Slash Pine (Pinus elliottii var. elliottii) Using Field Trials Planted in Large Block Plots
(2003)Predicted breeding values were validated using realized gains estimated from large-rectangular-plot field trials from the first generation breeding population of slash pine (Pinus elliottii var. elliottii Engelm.) in the ... -
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 ... -
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 ... -
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, ... -
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 ... -
Genetic Variation of Juvenile Wood Properties in a Loblolly Pine Diallel Test
(2003)The reduced rotation age for loblolly pine plantations has resulted in an increased percentage of juvenile wood. Juvenile wood has lower wood density, shorter tracheid length and higher lignin content than mature wood. The ... -
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 ... -
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 ... -
Top Grafting Longleaf x Slash Pine F1 Hybrids on Mature Longleaf and Slash Pine Interstocks
(2003)Top grafting is used to accelerate the breeding cycle of loblolly pine (Pinus taeda L). Scions, collected from seedlings as young as 1 year from seed, are grafted onto mature interstocks of the same or a related species. ... -
Genetic Variation in Stone Pine Half-Sib Progenies
(2003)Total height, annual height growth, root collar diameter, total number of branches and total number of buds around the leader bud were recorded at age 6. The experimental material was included 136 half-sib families originating ... -
Variation in Estimation of Genetic Parameters from Small Disconnected Diallel Mating
(2003)Diallel mating designs are widely used in plant improvement programs to estimate additive and dominance genetic variances, and to provide a base population for advanced selection. It is very common to limit the number of ... -
Implementation of Third-Cycle Loblolly Pine Breeding Plan - N. C. State University-Industry Cooperative Tree Improvement Program
(2003)The N. C. State University-Industry Cooperative Tree improvement Program has officially completed two cycles of loblolly pine breeding and testing program. As the third cycle selections are being completed, an efficient, ...
