This publication includes a set of protocols and standards for the production of quality planting material of the most important vegetatively reproduced crops, namely: banana, plantain and other Musaceae, cassava, cocoyam, garlic, hausa potato, konjac, mashua, oca, potato, sweet potato, taro, ulluco and yam. Prepared by FAO, in collaboration with the International Potato Centre and a team of international experts, it follows the principles and approach of FAO's Quality Declared Seed System. Vegetatively propagated crop species contribute significantly to the agriculture and food production sectors of many developing countries and regions and to their food security. The current availability and dissemination of advanced reproduction technologies, in particular for micropropagation, have increased the scope for improvement and development of disease-free planting materials for these crops. However, in spite of their potential, they have received little attention in formal seed quality regulatory systems. Thus, these protocols and standards were developed to serve as practical and useful tools for seed producers and technicians at the community level as well as for national seed services and the agricultural research community in developing countries. Improved quality of planting materials will contribute significantly to improved agricultural production and productivity and to global food security. Book jacket.

The quality declared seed system, as set out in the FAO Plant Production and Production Paper No. 117 (1993, ISBN 9251032785) has been widely used, particularly by those working in the field of emergency seed supply and as a source of practical information on seed standards for a range of crop species. The system provided an alternative for seed quality assurance, which was less demanding than full seed quality control systems. This publication sets out a revised version, prepared by an expert consultation, which offers a more explicit recognition of the role of national policies and the impact of some recent international obligations on seed provision and a clearer explanation on how quality declared seeds can accommodate local varieties. The list of crops now includes 92 species, of which 21 include open pollinated and hybrids and one includes also a synthetic variety. In making this update, FAO sought to improve seed supplies to farmers and thus to contribute to food security.

This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.

This book will convince the reader to care about fruit and vegetables and to see that the small-scale production of these crops is fundamental to achieving sustainable development goals. In five chapters, the reader will learn about the challenges and rewards for producers, sellers, and consumers. Chapter 1: a working definition for fruit and vegetables, making the case for supporting small-scale farmers and value chains. Chapter 2: options for farm management to ensure that production is sustainable including genetic resources, seed systems, management of water, soil, nutrients, and control of pests and diseases. Chapter 3: options to integrate small-scale commercial fruit and vegetable farmers into socially inclusive value chains, including innovative post-harvest handling services, market linkages, and reducing food loss and waste. Chapter 4: options for practitioners and policymakers at different governmental, institutional and social levels to promote the sustainable production and consumption of safe, nutritious, and affordable fruit and vegetables. Chapter 5: key interventions and innovations to facilitate the sustainable production of fruit and vegetables in low- and middle-income countries across the world. This publication takes readers on a journey introducing them to a diverse array of fruit and vegetables through colorfully illustrated studies from around the world. It justifies the importance of these crops and it encourages readers to take an active role both in promoting fruit and vegetable production and in encouraging more people to eat them.

Based on twenty years of global research, this is the first comprehensive reference on crop genetic diversity as it is maintained on farmland around the world. Showcasing the findings of seven experts representing the field of ecology, crop breeding, genetics, anthropology, economics, and policy, this invaluable resource places farmer-managed crop biodiversity squarely in the center of the science needed to feed the world and restore health to our productive landscapes. It will prove to be an essential tool in the training of agricultural and environmental scientists seeking the solutions necessary to ensure healthy, resilient ecosystems for future generations.--

This comprehensive book, comprising 20 chapters contributed by respected academics in their respective fields, highlights the immense contribution of traditional medicine to the discovery and development of modern drugs. Each chapter provides in-depth details, stimulating experts to further explore the flora used in traditional medicines and inspiring younger investigators to delve into the mysterious world of secondary metabolites in their quest for novel molecules. This book is of immense value to scientists, academicians, researchers, and students alike, making it a valuable addition to personal collections and libraries.

This book covers a range of important topics on crop and animal genetics, breeding and genomics, as well as biodiversity and genetic resources conservation and utilization reflecting three thematic sections of working groups of the Biotechnology Society of Nigeria. The topics range from agricultural biotechnology, including genetically modified organisms and gene-editing for agronomically important traits in tropical crops, to Nigeria’s mega biodiversity and genetic resources conservation. This book will engender a deeper understanding of underpinning mechanisms, technologies, processes and science–policy nexus that has placed Nigeria as a leader in biotechnology in Africa. The book will be useful reference material for scientists and researchers working in the fields of food and agricultural biotechnology, bioinformatics, plant and animal genetics, breeding and genomics, genetic resources conservation and enhancement. Emphasizes recent advances in biotechnologies that could ameliorate the high-level global food and nutrition insecurity through plant and animal genetics, breeding, as well as genomics Provides detailed information towards harnessing indigenous bioresources for food and nutrition security and climate change adaptation Introduces new frontiers in the area of genomics, most especially their relevant applications in crop and animal breeding Reviews biotechniques that could enhance plant genetic resources conservation and utilization Discusses current biotechnological approaches to exploit genetic resources including the development of synthetic hexaploid wheat (SHW) for crop adaptation to the increasingly changing global climate

The book offers a rich toolkit of relevant, adoptable ecosystem-based practices that can help the world's 500 million smallholder farm families achieve higher productivity, profitability and resource-use efficiency while enhancing natural capital.
