This book was released on 1985 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Genetic and environmental components of variance for 2-year heights of offspring from inter- and intra-provenance matings in Scotch pine (Pinus sylvestris L.) were studied to determine which provenances and selection methods should be used in a program to improve ornamental and Christmas trees. The study represents 11 experiments (parental groups), consisting of families from 7 diallel matings minus selfs in 5 different provenances, 3 factorial matings between provenances, and 1 from open pollination. The seedlings for the 11 experiments were grown in pots and in a nursery for 2 years. Heritability estimates of 2-year height from inter- and intra-provenance matings tended to be larger on a family basis than on an individual basis, with the larger estimates being from nursery evaluations. In general, additive genetic variance was larger than dominance variance, although dominance variance increased in provenance hybrids. Nursery evaluation was preferred to pot evaluation of 2-year height because heritability estimates were larger and error variances were smaller for the experiments evaluated. Individual selection in the nursery within the German provenance seems to be the best method for improvement of 2-year height of the provenances evaluated in this study, although the rate of improvement in the Spanish provenance may be greater. Simple recurrent selection would be a good method for improvement of traits important to the Christmas tree producing industry. S3.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Forest Genetics examines some of the basic genetic concepts typically used in forestry and tree improvement studies, including Mendelian and population genetics. It also describes techniques that are generally useful in tree improvement work, including individual tree selection and breeding, provenance testing, species and racial hybridization, and introduction of exotics. Organized into 19 chapters, this volume begins with an overview of forest genetics and problems associated with forest genetics. It then discusses concepts from basic genetics, including chromosome structure and function; DNA and RNA; nongenetic inheritance; and genotype versus phenotype. Other chapters focus on inbreeding: complete elimination of homozygous recessive trees; mutation and migration; and controlled pollination and vegetative propagation. The book also covers the establishment and measurement of test plantations; general principles and methods of selective breeding; choice of breeding method and type of seed orchard; heritability and genetic gain; geographic variation in Scotch pine and American trees; species and racial hybridization; chromosome studies; and polyploidy and haploidy breeding. This book is a valuable resource for foresters, professional tree breeders, and those with or without previous training in genetics or forestry.

This book was released on 2018-03-17 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Genetic Gains From Tree Improvement of Ponderosa Pine in Southern Idaho The basis for a practical tree improvement program of ponderosa pine in southern Idaho is contained in l6 - year old family evaluation tests. As detailed in preceding publications (wang 1967; Wang and Patee 1974, 1976; Rehfeldt primary objectives of the tests are: to develop seed zones and seed transfer guidelines that account for genetic adaptations to natural environments, to identify outstanding individual trees and populations from which wind-pollinated seeds will provide genetic gains to artificial reforestation, and to provide materials and information prerequisite to future breeding programs. The present analyses of 16-year height utilize experimental materials more fully described in a series of papers that have assessed performance at ages 3, 8, and 11. Test plantations currently require thinning; therefore, it is appropriate to consider alternative plans for the future research program and for development of seed orchards.
