Book Description
While preparing the first edition of this textbook I attended an extension short course on writing agricultural publications. The message I remember was "select your audience and write to it. " There has never been any doubt about the audience for which this textbook was written, the introductory course in crop breeding. In addition, it has become a widely used reference for the graduate plant-breeding student and the practicing plant breeder. In its prepa ration, particular attention has been given to advances in plant-breeding theo ry and their utility in plant-breeding practice. The blend of the theoretical with the practical has set this book apart from other plant-breeding textbooks. The basic structure and the objectives of the earlier editions remain un changed. These objectives are (1) to review essential features of plant re production, Mendelian genetic principles, and related genetic developments applicable in plant-breeding practice; (2) to describe and evaluate established and new plant-breeding procedures and techniques, and (3) to discuss plant breeding objectives with emphasis on the importance of proper choice of objec tive for achieving success in variety development. Because plant-breeding activities are normally organized around specific crops, there are chapters describing breeding procedures and objectives for the major crop plants; the crops were chosen for their economic importance or diversity in breeding sys tems. These chapters provide a broad overview of the kinds of problems with which the breeder must cope.

Book Description
Over the last 50 years there has been a growing appreciation of the important role that farmers play in the development and conservation of crop genetic diversity, and the contribution of that diversity to agro-ecosystem resilience and food security. This book examines policies that aim to increase the share of benefits that farmers receive when others use the crop varieties that they have developed and managed, i.e., ‘farmers varieties’. In so doing, the book addresses two fundamental questions. The first question is ‘how do farmer management practices – along with other factors such as environment and the breeding systems of plants – affect the evolution and maintenance of discrete farmers’ varieties?’ The second question is ‘how can policies that depend on being able to identify discrete plant varieties accommodate the agricultural realities associated with the generation, use and maintenance of farmers’ varieties?’ This focus on discreteness is topical because there are no fixed, internationally recognized taxonomic or legal definitions of farmers’ varieties. And that presents a challenge when developing policies that involve making specific, discrete farmers’ varieties the subject of legal rights or privileges. The book includes contributions from a wide range of experts including agronomists, anthropologists, geneticists, biologists, plant breeders, lawyers, development practitioners, activists and farmers. It includes case studies from Asia, Africa, Latin America and Europe where, in response to a diversity of contributing factors, there have been efforts to develop policies that provide incentives or rewards to farmers as stewards of farmers’ varieties in ways that are sensitive to the cultural, taxonomic and legal complexities involved. The book situates these initiatives in the context of the evolving discourse and definition of ‘farmers' rights’, presenting insights for future policy initiatives.

Book Description
Following on from the CGIAR study by Evenson and Gollin (published by CABI in 2003), this volume provides up-to-date estimates of adoption outcomes and productivity impacts of crop variety improvement research in sub-Saharan Africa. The book reports on the results of the DIIVA Project that focussed on the varietal generation, adoption and impact for 20 food crops in 30 countries. It also compares adoption outcomes in sub-Saharan Africa to those in South Asia, and guides future efforts for global agricultural research

Book Description
Crop plant varieties developed by local farmers, commonly referred to as ‘farmers' varieties’, are problematic because there are no fixed taxonomic or legal definitions of them. As a result, policies to increase the share of benefits farmers receive from the use of such varieties struggle to have an effect. Aiming to clarifying these issues, this volume explores the nature of farmers’ varieties in the context of their biological, social and legal significance. The book addresses the complexities of defining what farmers’ varieties are and how they differ from one another and from generic varieties. It then charts the evolution of the concept of ‘farmers’ rights’, from the dawn of ‘genetic resources’ as a subject worthy of international attention, to the first legal recognition of the concept, through to current efforts to develop national level policies and laws. Further, the book examines outstanding policy-making challenges linked to the absence of fixed taxonomic or legal definitions of farmers’ varieties. Case studies are included from Africa, Asia, Europe and South America in which farmers, researchers and policy advocates have been confronted with the issues raised in this book. Various solutions are considered based on revised or new definitions of farmers’ varieties that reflect the biological and cultural realities in which they are produced, and the relative costs and benefits of attempting to implement each of the policies discussed.

Book Description
In modern days, crop improvement is a multidisciplinary division of agriculture. In this book, entitled, Breeding, Biotechnology and Seed Production of Field Crops, emphasis has been given on principles, methods and practices in plant breeding, biotechnology in crop improvement and seed production of field crops. The book has been written for all sections of learners, educators and staff-members of seed industries. Particular importance has been underlined for postgraduate students who specialize in plant breeding and seed science. Each chapter of the book has been designed as per the recommended of syllabus of Indian Council of Agricultural Research for the postgraduate students of various Agricultural Universities in our country. This book has been divided into two major parts- i) Principles of crop breeding and ii) Methods and practices of crop improvement and seed production of individual field crop. The book contains total of 18 chapteFirst three chapters are related to shed light on the basic-principles and remaining chapters deal with methods and practices of individual crop for improvement and seed production. We hope that the book will be ready to lend a hand to the advanced undergraduate students doing plant breeding in elective, postgraduate students who opted plant breeding, teachers, researchers and staff-members of private seed companies of this field of specialization.
