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 ... -
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 ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
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. ... -
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 ... -
Third-Cycle Breeding Strategy for Slash Pine by the Cooperative Forest Genetics Research Program
(2003)The Cooperative Forest Genetics Research Program (CFGRP) third-cycle slash pine tree improvement program will span 11 years (2003-2013), involving a breeding population of 360 third-cycle selections and 20 full-sib (FS) ... -
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 ... -
Pioneering Tree Improvement in Oklahoma
(2003)The pioneering tree improvement work in Oklahoma started in 1965 when Clayton Posey moved from Auburn University to Oklahoma State University. Clayton was hired by Glen Durrell (Department Head) to fill a teaching/research ...
