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.

In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequencies (Khush, 1973). Gene expression in the pollen might thus at least appear to be a phenomenon of trivial consequence. Indeed, Heslop-Harrison (1979) rightly termed the gametophytic portion of the angiosperm life cycle, the "forgotten generation." This neglect, however, came about despite subtle but constant indications that pollen is the site of intense gene activity and selection. For example, Mok and Peloquin (1975) demonstrated that relatively heterozygous diploid pollen shows heterotic characteristics whereas relatively homozygous diploid pOllen does not. This was proof positive that genes are expressed (that is, transcribed and translated) in the pollen. 1 Department of Botany, University of Massachusetts Amherst, MA 01003, USA viii However, the implications for pollen biology of even this recent and well known study were not widely recognized.

Mites are among the most important arthropods in greenhouses, both as pests causing economic injury to greenhouse crops, and as natural enemies used in the biological control of pest insects and other mites. Because of their minute size, mites are much less well known than insects. This book describes the biology, identification and control of such mites and the topics covered include an introduction to the Acari, illustrated keys to orders, families and selected species, the control of pest mites, and the role of beneficial mites in biological control. The book will be of interest to those working in entomology, crop protection and horticulture.

Advances in plant cell molecular biology have considerably increased our understanding of pollen-pistil barriers, particularly those operated by incompatibility mechanisms, and, at the same time, demonstrated the complexity and diversity of rejection systems once considered to be relatively simple. This book reviews the impressive knowledge acquired in the last century on the biology, particularly the inheritance and population genetics of self-incompatibility, and presents the new approaches to the study of the structure, function and evolution of incompatibility alleles and the analysis of cell-cell recognition and pollen rejection. The different methods now available for transforming the breeding behaviour of higher plants are also discussed.

The conservation of crop genetic resources is one of the important elements in efforts to sustainably increase agricultural production in low-income countries, and to guarantee long-term food security, especially for the low-income population groups in these countries. Horticultural crops, as high-value crops, have an important role to play in revitalizing rural economies and can add significantly to national economies. Moreover, horticulture provides more than twice the number of jobs compared to traditional cereal crop production, and the shifting of conventional agriculture towards high-value horticulture has increased employment opportunities in developing countries. To exploit this potential, researchers need a vast array of horticultural genetic resources and information on new traits. Horticultural crops, which are only a part of PGRFA (Plant Genetic Resources for Food and Agriculture), are characterized by a wide and varied range of species. In fact, there are five major horticultural crop groups: fruit and nut crops, vegetables, food legumes, roots and tubers, and lastly the ornamental and medicinal group. In this context, the present book provides a comprehensive overview of the current state of conservation and utilization of horticultural genetic resources, addressing contemporary approaches to conservation in connection with different technologies, including biotechnological approaches as practised in India and in some cases, globally. It includes a brief chapter on the unique nature of horticultural genetic resources, providing a rationale for viewing them as being distinct from field crop genetic resources. Subsequent chapters share insights on protocols for the conservation of selected horticultural crops ex situ, and focus on the increased need to complement these efforts with in situ conservation approaches. Geospatial tools are also briefly described, emphasizing their utility with regard to mapping and managing resources. The book also explores the wild gene pool in horticulture crops; discusses legal aspects related to horticultural genetic resources and biotechnological aspects; and describes the key aspects of sustainable management and replenishment. Given its scope, the book offers a valuable resource for all horticulturists, graduate students, researchers, policymakers, conservationists, and NGOs engaged in horticulture in particular and biodiversity in general.

This encyclopedic reference work on pharmacognosy covers the study of those natural substances, principally plants, that find a use in medicine. Its popularity and longevity stem from the book's balance between classical (crude and powdered drugs' characterization and examination) and modern (phytochemistry and pharmacology) aspects of this branch of science, as well as the editor's recognition in recent years of the growing importance of complementary medicines, including herbal, homeopathic and aromatherapy. No other book provides such a wealth of detail. A reservoir of knowledge in a field where there is a resurgence of interest - plants as a source of drugs are of growing interest both in complementary medicine fields and in the pharmaceutical industry in their search for new 'lead compounds'. Dr Evans has been associated with the book for over 20 years and is a recognised authority in all parts of the world where pharmacognosy is studied, his knowledge and grasp of the subject matter is unique. Meticulously referenced and kept up to date by the editor, new contributors brought in to cover new areas. New chapter on 'Neuroceuticals'. Addition of many new compounds recently added to British Pharmacopoeia as a result of European harmonisation. Considers development in legal control and standardisation of plant materials previously regarded as 'herbal medicines'. More on the study of safety and efficacy of Chinese and Asian drugs. Quality control issues updated in line with latest guidelines (BP 2007).
