Plant breeding has played a significant role in the development of human civilizations. Conventional plant breeding has significantly improved crop yield by genetically manipulating agronomically important traits. However, it has often been criticized for ignoring indigenous germplasm, failing to address the needs of the marginal and the poor farmers, and emphasizing selection for broad instead of local adaptation. Participatory plant breeding (PPB) is the process by which the producers and other stakeholders are actively involved in a plant-breeding programme, with opportunities to make decisions throughout. The Working Group on Participatory Plant Breeding (PPBwg) was established in 1996 under the framework of the Consultative Group on International Agricultural Research (CGIAR). Research in PPB can promote informed participation and trust in research among consumers and producers, and in recent years, PPB has had a significant impact on food production by quickly and cost-effectively producing improved crop varieties. At the same time, there has been significant research in the area. PPB offers significant advantages that are particularly relevant to developing countries where large investments in plant breeding have not led to increased production, especially in the marginal environments. In addition to the economic benefits, participatory research has a number of psychological, moral, and ethical benefits, which are the consequence of a progressive empowerment of the farming communities. PPB can empower groups such as women or less well-off farmers that are traditionally left out of the development process. This book explores the potential of PPB in the coming decades. The topic is more relevant since international breeding efforts for major crops are aimed at decentralizing local breeding methods to better incorporate the perspective of end users into the varietal development process. The first book incorporating the upcoming research on this novel breeding approach, it reviews the important tools and applications of PPB in an easy-to-read, succinct format, with illustrations to clarify these complex topics. It provides readers with a basic idea of participatory plant breeding as well as advances in the field and insights into the future to facilitate the successful integration of farmers into breeding programmes. This book is a valuable reference resource for agriculturists, agricultural advisers, policy makers, NGOs, post-doctoral students and scientists in agriculture, horticulture, forestry and botany.

The Green Revolution averted the threat of famine through the rapid adoption of improved rice varieties. However, despite this huge success, hundreds of millions of poor rice-farming families in rainfed areas still live in poverty and suffer from food (rice) insecurity. Despite many released improved rice varieties for rainfed conditions, farmers still use local varieties that can withstand drought and floods but have low yields or they use the same varieties for many years because of a lack of better varieties. Rainfed rice farmers are slow to adopt improved varieties because of several problems. One problem is more of extension than breeding - many farmers, particularly those living in remote rainfed areas, may not have access to or information about the seed of new varieties. Another problem is that variety testing programs are often conducted on-station, which does not represent farmers' fields. Moreover, conventional rice breeding programs usually seek farmers' input only at the very end of the process, when newly released varieties, usually one or two per year, are evaluated in on-farm demonstration trials. Often, in remote and unfavorable areas, subsistence farmers, who comprise the majority of the rural farming population in Asia, give importance to social and cultural dimensions aside from the agronomic performance of the new rice varieties. The complexities of developing acceptable varieties for variable and stressful rainfed environments require that breeders become deeply familiar with men and women farmers' needs and preferences. Since 1977, IRRI has been making efforts to improve communication among farmers, breeders, and extension workers so that men and women farmers' concerns and preferences are considered in plant breeding objectives. Participatory varietal selection (PVS) is a simple way for breeders and agronomists to learn which varieties perform well on-station and on-farm and to obtain feedback from the potential end users in the early phases of the breeding cycle. It is a means for social scientists to identify the varieties that most men and women farmers prefer, including the reasons for their preference and constraints to adoption. Based on IRRI's experience in collaboration with national agricultural research and extension system partners and farmers, PVS, which includes "researcher-managed" and "farmer-managed" trials, is an effective strategy for accelerating the dissemination of stress-tolerant varieties. PVS has also been instrumental in the fast release of stress-tolerant varieties through the formal varietal release system. This guide on PVS will complement the various training programs given by IRRI for plant breeders, agronomists, and extension workers engaged in rice varietal development and dissemination.

"The concept of grasslands as a global resource is not new. Indeed many recognised authorities have been canvassing for a global approach to understanding, managing and exploiting this resource for many years. This is the first book that gathers together leading experts from around the world to outline our current understanding of this complex ecosystem, the ways in which it can be enhanced and utilised and where the research challenges are for the future. The following themes unite the book: - Efficient production from grassland; - Grassland and the environment; - Delivering the benefits from grassland. The reader is given an in depth understanding of the biology of the system and how grasslands are crucial for soil stabilisation and water quality. Secondly, much attention is given to how grasslands offer the possibility of increasing food supply and income generation, which is a hugely important but often ignored facet in today’s climate of extensification and biodiversity. Current advances in the grassland sciences have a proven potential to promote the economic development and environmental stability of regions, nations and peoples, particularly in some of the most resource-limited areas of the world. Approaches for achieving the most effective development and adoption of new technology are reviewed."
