Breeding For Ornamentals Classical And Molecular Approaches

In this book we bring together the most up-to-date information on developments, both basic and applied, that already have or are expected to impact the field of ornamental breeding. These include classical and molecular techniques, traditional and high-throughput approaches and future trends. Since not only professional scientists, but also thousands of future scientists/students as well as amateur breeders around the world contribute heavily to the field of ornamental breeding, an introductory section dealing with the basics of molecular and classical genetics and the evolution of floral diversity is included. This should enable the reader to bridge the gap between traditional and molecular genetics. Classical approaches to the creation/selection of genetic variability, including mutation and tissue culture-aided breeding, are presented. Processes affecting ornamental and agronomic traits at the molecular level are delineated, along with an in-depth analysis of developments in the protection of intellectual property rights. The thoughts and strategies of molecular and classical geneticists, which are not always complementary or even compatible, are presented side by side in this book, and will serve to spark the imaginations of breeders as well as students entering the exciting world of state-of-the-art ornamentals.

Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one or two volumes per year.

The purpose of this book is to bring together the most recent knowledge concerning the genetic improvement of ornamental plant species. Active researchers of many aspects of the genetics and breeding of these species have written chapters organized into three sections: Cytogenetics, Quantitative Genetics and Molecular Genetics. These titles identify the basic tools used in a variety of breeding situations. Some are traditional and well established; others offer new and exciting challenges for the future. vii Introduction The purpose of this book is to bring together recent knowledge concerning the genetic improvement of ornamental plant species. In the 20th century flower breeding has become widespread leading to many improvements in phenotypic and production characteristics of ornamental species. These methods depends on the creation and subsequent selection of genetic vari ability. Lack of variability in gene pools has been a chief limitation to the success of flower breeding. Recent progress in molecular biology makes it possible to add genetically well-defined characteristics to gene pools, thus increasing the potential for genetic improvement. These methods also enable the specific silencing of genetic information to accomplish an intentional loss of function. This book compiles current knowledge of the cytogenetics, quantitative genetics, and molecular genetics of ornamental plant species. The three sections identify the basic tools used in a variety of breeding situations.

Find out how biotechnology can produce more nutritious fruits and vegetables, more colorful flowers, and grass that needs less water—and mowing! Plant Biotechnology in Ornamental Horticulture presents an in-depth overview of the key scientific and technical advances, issues, and challenges in one of the fastest growing segments of the agriculture industry. This comprehensive book covers 19 different topics related to the use of transgenic plant technology to improve ornamental plants, ranging from metabolic engineering of flower color and scent to improving cold, drought, and disease tolerance in horticultural and ornamental crops to the economics of horticultural biotechnology. Horticulture provides color and flavor to the foods we eat and variety to the products we use, and helps us sustain a healthy environment. Plant Biotechnology in Ornamental Horticulture examines the importance of biotechnology in cultivating garden crops-including fruits, vegetables, flowers, and ornamentals such as plants used for landscaping-by reducing pesticide use, reducing soil erosion, and developing plants with improved nutrition. Leading educators and horticultural professionals address important current and future topics, including micropropagation and regeneration, the use of molecular techniques for genetic improvement, molecular-assisted breeding, abiotic stress, the development of disease resistance, protection from insects, herbicide tolerance, controlled flowering, modifying color and fragrance, plant architecture, and senescence. Plant Biotechnology in Ornamental Horticulture examines: * ornamental plant transformation * molecular phylogeny * drought response and drought tolerance engineering * transgenic approaches to viral, bacterial, and fungal disease resistance * vegetable propagation by cuttings * the promotion of flowering * molecular aspects of leaf morphogenesis * transgenic manipulation * controlling invasive plants * plant hormones, including ethylene, gibberellins (GAs), auxin, cytokinin, and abscisic acid (ABA) * and much more Plant Biotechnology in Ornamental Horticulture is essential reading for plant breeders, physiologists, agronomists, molecular biologists, cropping system specialists, as well as for educators and students involved in horticulture.

Ornamental plants are economically important worldwide. Both growers and consumers ask continuously for new, improved varieties. Although there are numerous ornamental species, ornamental plant breeding and plant breeding research is mainly limited to some major species. This book focuses on the recent advances and achievements in ornamental plant breeding. The first part of the book focuses on plant traits and breeding techniques that are typical for ornamental plants. Eminent research groups write these general chapters. For plant traits like flower colour or shape, breeding for disease resistance and vase or shelf life are reviewed. General technical plant breeding chapters deal with mutation breeding, polyploidisation, in vitro breeding techniques and new developments in molecular techniques. The second part of the book consists of crop-specific chapters. Here all economically major ornamental species are handled together with selected representative species from different plant groups (cut flowers, pot plants, woody ornamental plants). In these crop-specific chapters, the main focus is on recent scientific achievements over the last decade.

Although a great deal of research on ornamental geophytes has been conducted since the beginning of the 1990s, current information has not been comprehensively presented to researchers and horticulturalists. Covering the latest advances in geophytes science, Ornamental Geophytes: From Basic Science to Sustainable Production provides up-to-date reviews on geophyte taxonomy, physiology, genetics, production, plant protection, and postharvest biology. Novel approaches to environmentally-friendly, sustainable production and integrated management have stimulated new research directions, and innovative biochemical and molecular methods have opened new avenues in taxonomy and breeding. In addition to the issues historically associated with traditionally growing countries, the book reviews the development of new production centers in Africa, Asia, and South America. In 20 chapters, this book reflects three main trends in plant science and horticulture: A demand for sustainable and environmentally friendly production Widespread employment of new molecular technologies The globalization of the production and marketing chains Thoroughly modern and in tune with the needs and methods of the geophytes industry, Ornamental Geophytes: From Basic Science to Sustainable Production will benefit not only researchers who have been engaged for years but also new researchers and students who must meet and challenge the existing dogmas. In addition, the information contained in this book is vital to bringing the value of flower bulbs to the worldwide consumers who are the most important and last links in the chain of utilization and profitability of all ornamental products.
