Forest growth and quality are critical for environmental sustainability, economic value, and biodiversity conservation. Genetic and biotechnological approaches offer significant advancements in enhancing these attributes. Traditional genetic selection has long been used to breed trees with desirable traits such as faster growth, disease resistance, and superior wood quality. Modern biotechnological methods, including genetic modification and CRISPR gene editing, allow for precise alterations in tree genomes, accelerating improvement processes. These technologies can introduce traits like enhanced carbon sequestration and resilience to climate change. Additionally, tissue culture techniques enable the mass propagation of superior genotypes, ensuring uniformity and high quality in forest plantations. Integrating genetic and biotechnological strategies not only improves forest productivity but also supports sustainable forestry practices by reducing the need for chemical inputs and preserving natural ecosystems. This book includes some of the vital pieces of research being conducted across the world, on various topics related to forest growth and quality. It will also provide interesting topics for research which interested readers can take up. The readers would gain knowledge that would broaden their perspective about this subject.
