Book Description
There is a concern in Canada about the narrowing genetic base of farm animal species, with the consequent need to consider the conservation of farm animal genetic resources as insurance for Canadian animal industries for the current and future changes in the environment, market demands, and selection goals. This document provides background on the need and importance of the conservation of farm animal genetic resources, and proposes concepts for a national system for conserving such resources. The document outlines international and national programs in germplasm conservation and presents discussion papers on issues related to conservation of farm animal genetic resources. These issues include the setting of conservation priorities, identifying at-risk populations, minimizing inbreeding, gene bank strategies, disease control for conservation, ownership and access of genetic resources, and research needs.

Book Description
This anchor volume to the series Managing Global Genetic Resources examines the structure that underlies efforts to preserve genetic material, including the worldwide network of genetic collections; the role of biotechnology; and a host of issues that surround management and use. Among the topics explored are in situ versus ex situ conservation, management of very large collections of genetic material, problems of quarantine, the controversy over ownership or copyright of genetic material, and more.

Book Description
The plant species that humans rely upon have an extended family of wild counterparts that are an important source of genetic diversity used to breed productive crops. These wild and weedy cousins are valuable as a resource for adapting our food, forage, industrial and other crops to climate change. Many wild plant species are also directly used, especially for revegetation, and as medicinal and ornamental plants. North America is rich in these wild plant genetic resources. This book is a valuable reference that describes the important crop wild relatives and wild utilized species found in Canada, the United States and Mexico. The book highlights efforts taken by these countries to conserve and use wild resources and provides essential information on best practices for collecting and conserving them. Numerous maps using up-to-date information and methods illustrate the distribution of important species, and supplement detailed description on the potential value these resources have to agriculture, as well as their conservation statuses and needs. There is broad recognition of the urgent need to conserve plant diversity; however, a small fraction of wild species is distinguished by their potential to support agricultural production. Many of these species are common, even weedy, and are easily overshadowed by rare or endangered plants. Nevertheless, because of their genetic proximity to agriculturally important crops or direct use, they deserve to be recognized, celebrated, conserved, and made available to support food and agricultural security. This comprehensive two-volume reference will be valuable for students and scientists interested in economic botany, and for practitioners at all levels tasked with conserving plant biodiversity.

Book Description
In recent decades, livestock producers have moved away from open grazing for a number of reasons, none having to do with the health of consumers. Genetic Resources, Chromosome Engineering, and Crop Improvement: Forage Crops demonstrates how state-of-the-art technology can encourage the raising of livestock in open pastures where they can be fed grasses grown in nature rather than meals enriched with hormones and other by-products. The volume brings together the world’s leading innovators in crop science who furnish information on the availability of germplasm resources that breeders can exploit for the improvement of major forage crop varieties including alfalfa, wheatgrass and wildrye grasses, Bahiagrass, birdsfoot trefoil, clover, Bermudagrass, and ryegrass. An introductory chapter outlines the cytogenetic architecture of forage crops, describes the principles and strategies of cytogenetic and breeding manipulations, and summarizes landmark research. Ensuing chapters provide a comprehensive account of each crop: its origin; wild relatives; exploitation of genetic resources in the primary, secondary, and tertiary, and, where feasible, quarternary gene pools through breeding and cytogenetic manipulation; and genetic enrichment using the tools of molecular genetics and biotechnology. . Certain to become the standard reference, this volume— Discusses taxonomy, genomic and chromosomal constitution, and the geographical distribution Stresses the role of germplasm exploration, maintenance, and assimilation for increasing yield Presents practical improvement methodologies including conventional, cytogenetic, mutation, molecular, cell and tissue cultures, and genetic transformation In addition to serving as fodder, forage crops provide ground cover, aid in abetting erosions, yield a number of pharmaceuticals, and are critical to honey production. Solving the world’s food crisis requires approaches that will lead to healthier, more enriched food sources, as well as more bountiful harvests. It also requires that we make the best use of resources we have. Moving livestock away from grain and back to forage crops is one approach that can help us achieve a balanced food chain capable of meeting ever-growing demand.
