DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKIn many developing countries, smallholder farmers cultivating vegetatively propagated crops (VPCs) have limited access to quality planting material. This constraint can limit both the yield of and returns on VPC cultivation. Yet policy and regulatory initiatives designed to strengthen access to quality VPC planting materials have been relatively unsuccessful to date. Part of the problem is the unique biological and economic characteristics of vegetative propagation and its distinctness from cereal crops, which dominate narratives on seed system reforms. Drawing on qualitative analysis of policy and practice, this study examines reform options related to quality assurance regulations in four crop-country combinations: cassava in Nigeria and Vietnam, and potato in Kenya and Vietnam. The study highlights theory and evidence on existing models of regulation; alternative models that may better incentivize cost-effective multiplication and distribution; and recommendations for policy, regulation, and investment in VPC seed markets. Findings indicate that regulations designed around strict and centralized quality control systems tend to limit market size, while more localized production systems are limited by both capacity and reach. These findings suggest the need for alternatives that balance a permissive regulatory regime with decentralized production systems, grassroots capacity development, market surveillance, and systems that integrate internal (producer-level) quality assurance with external (regulatory) quality assurance.

DOWNLOAD EBOOKThis volume continues the series of books on “Plant Pathology in the 21st Century”, and contains the papers given at the 10th International Congress of Plant Pathology (ICPP 2013) held in Beijing, August 25-30, 2013 concerning seed health. Many pathogens are transmitted throughout infected seeds and propagation material .The fact that propagation material production is very much concentrated in few establishments, favors the quick spread of new diseases throughout seed commercialization. This phenomenon is very much accelerated in a globalized system. The book covers case studies of contamination, aspects of detection and diagnosis as well as disease management strategies, with special emphasis towards seed treatments with unconventional products. This book will be useful for all plant pathologists as well as students in advanced courses.

DOWNLOAD EBOOKIn horticulture, plant propagation plays an important role, as the number of plants can be rapidly multiplied, retaining the desirable characteristics of the mother plants, and shortening the bearing age of plants. There are two primary forms of plant propagation: sexual and asexual. In nature, the propagation of plants most often involves sexual reproduction, and this form is still used in several species. Over the years, horticulturists have developed asexual propagation methods that use vegetative plant parts. Innovation in plant propagation has supported breeding programs and allowed the production of high quality nursery plants with the same genetic characteristics of the mother plant, free of diseases or pests.
