Beskrivelse
The performance of any biological population is a function of both the hereditary potentials of the individuals making up the population and the extent to which such potentialities are permitted to be realized by the environment in which the population is growing. Fortunately, today in forestry intensive management through artificial regeneration and establishment of plantations or what may be more aptly called man-made forests has come to be practiced on an extensive scale in many countries. This offers the opportunity for better management of the conditions under which the trees grow and choosing appropriate reproductive materials which will have the capacity to exploit to the best advantage the environment provided and which can often be tailored to meet the specific needs. The area of potential production is often large and even small improvements in productivity may be very significant both in terms of social benefits and production of raw material to meet industrial demand. Worldwide tree planting activity shows that tree breeding is the most effective component of forestry for success in afforestation.
The objective of this bbook is to consolidate and summarize the concepts that are necessary for useful and efficient tree breeding programs. The essential feature of this book is to illustrate a general approach to Forest Tree Breeding with particular reference to Dalbergia sissoo. The first chapter of the book describes briefly silviculture, wood properties, utilization, and other important features of Dalbergia sissoo, besides the importance and history of forest genetics and tree breeding. The subsequent chapters of the book describe reproductive biology, genetics, variation and adaption, provenance selection, plus tree selection and progeny testing, seed production and certification, and genetic improvement strategy. Some specific examples, figures, and data are used to clarify the concepts. The book also covers references, a glossary, a list of institutes and organizations of special interest to forest tree breeders, and a list of journals and magazines useful for forest tree breeders.
It is hoped that the book will be of special value to students, teachers, and researchers dealing with Forest Genetics and Tree Breeding.
