Available in PDF, EPUB and Kindle. Book excerpt: Breeding Pest-Resistant Trees documents the proceedings of a N.A.T.O. and N.S.F. Advanced Study Institute on Genetic Improvement For Disease and Insect Resistance of Forest Trees held in Pennsylvania State University from August 30 to September 11, 1964. This book compiles the study and research of geneticists, pathologists, entomologists, and foresters concerned with the genetic resistance of forest trees to pests and breeding programs for disease- and insect-resistant trees. This compilation is divided into three parts. The first part discusses about the résumés of research related to forest tree pest resistance by geographic regions. Part II focuses on the reports of significant research advances in the basic knowledge of disease and insect resistance of forest trees, while Part III includes the discussion of approaches and methods for genetic improvement in pest resistance of forest trees. The topics covered include the variation and inheritance of pest resistance in forest trees; environmental effects on the host-pest relationship; review of basic knowledge of forest tree pest resistance; selection for pest resistance in wild populations; and testing and evaluating inherent pest resistance. This publication is a good source for students and individuals conducting work on the resistance of forest trees to diseases and pest insects.
