The volume on oilseed crops is developed as a part of a series on “Handbook of Agrobiodiversity: Conservation and Use of Plant Genetic Resources”. The handbook would function as a ready reference book for availability of PGR globally, along with specific source, wherefrom they can be procured, and used breeding programs, particularly to overcome various crop production constraints and to improve productivity and quality. The volume on floriculture and ornamental plants will be the source of basic information on origin and evolution and global dispersal of cultivated species of ornamentals. Presently, floriculture has established its credibility in improving income through increased productivity, generating employment and in enhancing exports. All research and developmental activities on ornamental crops are essentially multi-disciplinary in nature recognizing local issues as well as country issue. Floriculture is developing as an area of high technology based frontier interdisciplinary area on scientific excellence. Floriculture has progressed both scientifically and commercially due to concentrated efforts made on multidisciplinary research. It is developing as an area of high technology based frontier interdisciplinary area on scientific excellence. The volume will contain all information about different ornamentals. This shall be put together to develop a complete documentation of the results of the research and demonstrations conducted by different scientists. The volume will provide an illustrated horto-taxonomical account of important ornamental species and cultivars, germplasm status and their usages, propagation, nursery management, techno-economics, conventional breeding, induced mutagenesis, new varieties, cytogenetics, tissue culture, characterization of varieties, dehydration of flowers etc. This volume will give a coherent and concise account on recent developments. It will deal with all the important and relevant aspects of floriculture. The publication of this volume is planned to reveal multifarious activities done on different aspects of floriculture so that innovations made so far can be used judiciously for this sector. This book shall provide authoritative review account of many aspects of current interest and progress in the field of floriculture. The topics included in the book are interdisciplinary and cater not only classical floriculture but also relevant modern aspects. The book will provide valuable data on different aspects and will be widely accepted by by professional scientists, researchers, teachers, students, floriculturists, technocrats and planners. The volume will be an invaluable asset to floriculture scientists.

The floricultural industry has been undergoing an unprecedented revolu tion in terms of the type of commodity produced and the production and marketing technology in both developed and developing countries. As a result of this revolution, as we know today, there is a flower for every purpose and for every person in the world, as is evident from the slogan of the Society for American Florists: "say it with flowers". In re cent years, the Latin American and European countries have become sizeable competitors for the North American fresh flower markets and the trend continues growing. Like any other crop production, floricultural production can be divided into three basic factors: (1) production costs (2) quality (3) transportation costs. All these must be optimum for this area or industry to be safe from competition. With increasing consumer awareness and the current recession, the pressure from the artificial floral products in dustry and also of neighbouring countries on the American fresh flower industry, and continued competition even amongst the growers, whole salers and retailers, quality in floricultural industry is becoming increas ingly important to all those concerned with handling these products. The visual quality aspects of the product are the sole determiner of consumer acceptability in this industry and, unlike fruits and vegetables, flowers cannot be marketed by just discarding the damaged portion.

Floriculture is one of the fastest-growing sectors of commercial agriculture world-wide with many highly profitable crops. Cultivation of flowers more pragmatic endeavor than other crops. Every day novel variety, new colour in any ornamental flower crop not only fascinates us but also gives a thrust to know more about their breeding technologies. Creation of diversity of new and domesticated flower crops by public and private sector flower breeders brings a fascination towards its breeding technology. The students while dealing with the breeding and biotechnology of flowers then they must required a base knowledge. Therefore emphasis has been given to present the book in its easiest form so that anyone can understand it without losing interest from it. It has been designed to cover all the aspects of breeding, the basic objectives, different breeding methods, methodology for improvement of specific crops, stress resistance, quality improvement, mutagenesis, genetic engineering and biotechnology.

Ornamental plants include herbaceous plants produced as bedding plants, greenhouse pot plants and cut flowers, as well as bulbs, trees, shrubs and vines. Ornamental plant production is of major and increasing importance worldwide. Basic scientific research in recent years has provided a better understanding of plant regeneration, genetics, growth and development. This has led to the development of technologies which can significantly improve ornamental species. This book reviews recent advances in the biotechnology of ornamentals. For example, genes have recently been identified for flower characteristics and pest resistance and these have been engineered into ornamental species. The book is divided into four main parts and is written by authors from the USA, UK, Canada, Netherlands, Australia and New Zealand. It is aimed primarily at workers in horticulture and plant biotechnology, but will also be of interest to plant physiologists, geneticists and molecular biologists.
