Local landraces are traditional crop varieties cultivated in specific locations. However, the intensification of modern horticulture has put these genotypes aside, since farmers tend to select hybrids or commercial cultivars due to higher yield, uniformity and marketability. The various landraces are very distinct in their quality features, therefore it is of high importance to highlight these differences and identify genotypes that could be further exploited by producing high added value products and by reinforcing local rural economies. The proposed Research Topic aims to reveal the importance of local landraces for sustainable horticulture, focusing on their special quality features as the result of adaptation to specific growing conditions after domestication.
Bringing dynamic back into vegetable gardening, seed saving, and breeding of plants and animals. A joyful and accessible approach to growing tasty, productive, and resiliently diverse food. Advocating a return to traditional regenerative horticulture methods of gardening and farming, while minimizing the use of current agricultural methods. Focusing on communities, and local varieties of crops and animals. Biodiversity and cross pollination allow selection for crops that thrive under ever changing conditions, while lessening the need for costly inputs, like poisons, fertilizer, materials, and labor. Less labor means more time for friends, family, music, dancing, or whatever it is that brings you joy. The book includes detailed suggestions for developing a more reliable food system using local crop varieties. The techniques taught in this book can bring self-reliance and sustainable food security to small scale back yard beginner gardens, large scale farms, and permaculture food forests. A chapter is devoted to pollination and the benefits of encouraging cross-pollination. Chapters are devoted to breeding tomatoes, corn, beans, squash, and grains. Tips on growing many other vegetable varieties are included. The appendix includes a summary of which vegetables and grains are easiest to work with. A chapter is devoted to extending the principles of local gardening to breeding chickens, honeybees, mushrooms, and trees. Reviews "Landrace Gardening is brilliant." Dan Barber, Blue Hill At Stone Barns, and Row 7 Seed Company "Landrace Gardening gives us a roadmap to the kind of joyful food security that we need for healing many of the most important wounds of our time." Jason Padvorac "The best part is that everything in this book is adaptable for any gardener." Jere Gettle- Baker Creek Heirloom Seed Company. "The western sustainable agriculture movement has long needed its own version of the 'One Straw Revolution'. Joseph Lofthouse provides just that. " Alan Bishop, Alchemist at Spirits Of French Lick "Awesome to see this process beginning to work in just one year." Josh Jamison, HEART Village "Inspiring. Empowering. VERY important work." Stephanie Genus "This book begins to spark the imagination to the possibilities of what we have lost and how to begin to resurrect the return to something even better." Karin Kee "Man is way too eager to take extra burdens upon his shoulders, babying and pampering the plant when it should be bred to do all the work itself. Landrace Gardening makes important progress in that direction." Dave Blanchard "No Homestead Or Garden Is Complete Without This Book!" EmsyDoodle "If one can learn to take a more free approach to gardening and seed saving you will experience much of the joy Joseph receives when he gardens." Andrew Barney
Landraces possess a very large genetic base in population structure and are dynamic populations of cultivated plants with historical origin, distinct identity, and without any formal crop improvement. They are often genetically diverse, locally adapted, and associated with traditional farming systems. Resistance genes to biotic and abiotic stress factors, which are especially diversified in landraces, are of great interest to plant breeders, faced with global climate challenge. In addition, gene pools made of different landraces grown in different ecological conditions can be used for wheat breeding to enhance quality; yield and other desirable agricultural parameters. An estimated 75% of the genetic diversity of crop plants was lost in the last century due to the replacement of high yielding modern varieties. There is, thus, an urgent need to preserve existing species, not only for posterity but also as a means to secure food supply for a rising world population. In this book, we provide an overview of wheat landraces with special attention to genetic diversities, conservation, and utilization.
Based on the 2010 conference 'Towards the establishment of genetic reserves for crop wild relatives and landraces in Europe', this book is the cutting-edge discussion of agrobiodiversity conservation. By considering the benefits of understanding and preserving crop wild relatives and landraces, it encompasses issues as wide-ranging and topical as habitat protection, ecosystem health and food security. "Agrobiodiversity Conservation" focuses on Europe, but is globally relevant. It is suitable for postgraduate students of conservation and environmental studies, conservation professiona.
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.
Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
Genetic diversity is one of the main resources sustaining human life. Food security largely depends on the availability and utilization of this diversity, which is of strategic importance for countries and companies. Conservation and utilization of biodiversity is thus currently an urgent area of global debate and concern. Barley is a major crop in the world used for food, feed and malt, and with a wide religious and ethnic importance. The crop was domesticated in Neolithic time in SW Asia and spread rapidly under cultivation to new areas. Nowadays it is one of the most widespread and widely adapted crops grown under contrasting edaphic conditions. Adaptations to new environments, different agricultural practices and selection for different uses have further added to the complex diversity pattern. Is it at all possible to give a complete picture of the diversity in a crop or wild species? Are we, by adding new technologies, only revealing parts of the diversity? Do different sets of data show similar or conflicting pictures of genetic diversity? Will the large genome size reduce the role of barley as a model organism in these current sequencing days? Or, are there still major reasons to continue to work with this beautiful crop? The aim of this book is to cover the complex issue of diversification in time and space in a single crop: barley. Leading scientists from various fields describe the entire variation pattern in different sets of characters and an attempt is made for a synthesis to a holistic picture. The book proposes ways to use the achievements of diversity studies in future research and breeding programmes.
National policies to support the conservation and use of landraces in production systems for sustainable agriculture.
This comprehensive 2007 survey of modern plant breeding traces its history from the earliest experiments at the dawn of the scientific revolution in the seventeenth century to the present day and the existence of high tech agribusiness. Murphy tells the story from the perspective of a scientist working in this field, offering a rationale and evidence-based insight into its development. Crop improvement is examined from both a scientific and socio-economic perspective and the ways in which these factors interact and impact on agricultural development are discussed, including debates on genetically-modified food. Murphy highlights concerns over the future of plant breeding, as well as potential options to enable us to meet the challenges of feeding the world in the 21st century. This thoroughly interdisciplinary and balanced account serves as an essential resource for everyone involved with plant breeding research, policy and funding, as well as those wishing to engage with current debates.
