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, ...
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 ...
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, ...
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 ...
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 ...
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 ...
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 ...
