The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.

This edited book deals with plant genetic resources and their status, availability, and ecological niche in natural habitat. Usage and conservation practices followed by various tribal communities and their rationale are also discussed in the book. The book explores application of biological tools to conserve plant species and optimization protocols for conservation and elicitation of secondary metabolites and other value addition products. The book is organized into sub-themes covering: (i) Ecological status of plant genetic resources (ii) Traditional ethnobotanical knowledge and conservation practices (iii) Ex-situ conservation practices and bioprospecting Globally, plant genetic resources are deeply rooted in culture and economy. Since the early 1990s, the changing socio-economic situation has increasingly put pressure on plant genetic resources, in some cases leading to a severe loss of their diversity. For this reason, most vulnerable areas at risk of genetic erosion have been demarcated and protected by forest laws and regulations. Therefore, this book brings to light the opinions of leading experts in the area of ecology, conservation biodiversity, ethanobotany, and bioprospecting of plant genetic resources. The book is for use by graduate and advanced undergraduate students and researchers in plant physiology, molecular biology, biochemistry, and agriculture. Additionally, it is extremely useful as a general reference on conservation of flora and large-scale cultivation.

Genes in the Field provides an interdisciplinary foundation for an important new conservation program: maintaining biological resources of crop plants within the systems where they have evolved. The book offers a truly global vision of the on-farm conservation movement and, like no other before it, provides a comprehensive review of the issues and challenges of on-farm conservation of genetic resources. The book's chapters are written by a collection of outstanding scholars and academics from a variety of disciplines; they include biologists, agronomists, anthropologists, economists, lawyers and agricultural development specialists. Genes in the Field is truly global in scope and multidisciplinary in character. It will appeal to a large, varied and international audience. Its most general appeal will be to professionals in the fields of conservation and agricultural development, particularly those who are involved in planning or implementing conservation programs. For course work, the book will be appropriate for graduate programs in agricultural development and conservation.
