This book is the first comprehensive compilation of knowledge on teak biology, ecology, clonal forestry, clonal registration, seed biology, and seed orchards. The teak genetic diversity, the sequenced genome, and transcriptomes from different tissues and their implications in modern tree improvement and material selection have been comprehensively discussed. The book also presents a narrative on wood characterization, wood chemistry, modern silviculture, growth and modelling, and economics of this valued tropical species. Altogether, the book contains about 200 pages over 16 chapters authored by globally reputed experts on the relevant field in this tropical tree. This book is useful to students, teachers, and scientists, and wood-based industries are interested in forestry, biology, seed orchards, breeding, genetic diversity, molecular genetics, in vitro culture, wood chemistry, and structural and functional genomics.

This book offers foundational knowledge to advance genomic approaches in forest tree improvement and genetic resource conservation. The tropical tree breeding sector has fallen behind in genomic breeding not due to a lack of resources but rather a limited understanding and an underdeveloped genomic breeding pipeline. While marker-assisted selection (MAS) has been the preferred method for incorporating genomic data into breeding programs, it primarily targets major genes, overlooking minor gene effects. This limitation makes MAS less effective for enhancing quantitative traits such as heartwood content.

The primary goal of statistical methodologies using whole-genome information is to predict promising candidates for breeding advancement/commercialization while efficiently managing resources such as land, labor, and, most critically, time. Given the long rotation period of forest tree crops, the ability to identify, select, and modify genotypes with high heritability for economically valuable traits within a shorter timeframe marks a significant advancement in breeding. This book provides comprehensive guidelines on leveraging genomic data, including pathogenomics, to breed resilient, future-ready trees and manage populations effectively. To reinforce these guidelines, the book presents case studies on species such as Tectona grandis, Santalum album, Casuarina, Shorea, Artocarpus, tropical and sub-tropical pines, and tropical fruit trees. Additionally, the book explores broader applications of genetic data, including timber tracing and the conservation of germplasm while minimizing genetic redundancy.

This book will be a valuable resource for tropical tree breeders and researchers, equipping them with the methods and tools needed to adopt advanced genomic breeding. Additionally, students and scholars will benefit from the comprehensive information it provides, enhancing their understanding of modern breeding techniques.
