Excerpt from Genotype Environment Interaction: A Case Study for Douglas-Fir in Western Oregon
Several questions about interaction in the Snow Peak low-elevation zone led to this study: Was it stable with age? What was its contribution to family performance in predictions at a range of sites? Was interaction a deeply embedded property of coast Douglas-fir (pseudotsuga menziesii (mirb.) Franco var. Menziesii) or characteristic of a few families or plantations only? Was it associated with parent origin or mainly a feature of within-population genetic variation?

Paperback. Condition: New. Print on Demand. This book explores the complex relationship between genetics and the environment in Douglas-fir trees, drawing on a detailed case study in one breeding zone of western Oregon. The author's research reveals the presence of genotype-environment interaction, a phenomenon where tree growth and performance vary significantly depending on the specific plantation site. This interaction, often overlooked in previous studies, is found to be a substantial factor influencing genetic gain predictions and models for predicting tree growth under different environmental conditions. The book further investigates the potential causes of genotype-environment interaction, considering factors such as parent tree origin, within-population genetic variation, and site productivity. The author argues that this interaction is likely a result of adaptive responses to local environmental conditions. The research presented here challenges the common assumption that genotype-environment interaction is negligible and emphasizes its importance in understanding Douglas-fir growth patterns and making accurate predictions about their performance in different environments. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
