Deployment of genetically improved loblolly and slash pines in the south
Foresters in the southern United States are responsiblefor more than 75 percent of the nation's tree planting, and more than 95 percent of the seedlings are genetically improved loblolly and slashExpand

Relatedness and status number in seed orchard crops
Status number is a measure of effective population size that is based on current relatedness only. Formulae are developed for group coancestry (=average coancestry) and status number for seed orchardExpand

Genetic parameters from a clonally replicated test of black spruce (Piceamariana)
A clonally replicated field test of full-sib black spruce (Piceamariana (Mill.) B.S.P.) progeny was established at four locations in Nova Scotia. Estimated variance components for 5-year heightExpand

Balancing Gain and Relatedness in Selection
Summary A population merit criterion, B ω , for a set of genotypes, ω, is formulated as where, c is a weighting constant, g w is the average of their breeding values, and Θω is the average coancestryExpand

Genetic variation in the diameter–height relationship in Scots pine (Pinus sylvestris)
Genetic parameters were estimated for the diameter-height (d-h) relationship and three other tree stem-form characteristics (total height, breast height diameter, and total tree volume) for data fromExpand

Estimating genetic gains from alternative breeding strategies for clonal forestry
Concepts and procedures are presented for the analysis of progeny trials that incorporate clonal replication as a means to resolve variance arising from nonadditive gene effects. Components of vari...

Prediction of genetic gain and gene diversity in seed orchard crops under alternative management strategies
Abstract Genetic gain and the gene diversity of seed crops from clonal seed orchards were formulated considering genetic selection, fertility variation and pollen contamination, and compared for fiveExpand

Genetic parameters and age–age correlations in a clonally replicated test of black spruce after 10 years
Height growth at 10 years from striking was assessed for clonally replicated full-sib black spruce (Piceamariana (Mill.) B.S.P) families tested at three locations in central Nova Scotia. VarianceExpand

Fertility Variation, Genetic Relatedness, and Their Impacts on Gene Diversity of Seeds From a Seed Orchard of Pinus thunbergii
Abstract Clonal differences in the number of male and female strobili were determined for five consecutive years in a clonal seed orchard of Pinus thunbergii in Korea. The effects of relatedness andExpand

Comparisons of genetic parameters and clonal value predictions from clonal trials and seedling base population trials of radiata pine
Different methods for predicting clonal values were explored for diameter growth (diameter at breast height (DBH)) in a radiata pine clonal forestry program: (1) clones were analyzed with a fullExpand
