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.

When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago. Though biometrical-genetical analyses point to dispersion of complementary genes - not overdominance - as the major cause of the phenomenon, plant breeders' experience still suggests a cautious, pragmatic approach to the dominance-overdominance controversy in breeding hybrid cultivars. Thus we are faced with a striking discordance between our limited comprehension of the causal factors and mechanism of heter osis on the one hand, and the extensive agricultural practice of utiliza tion of hybrid vigor on the other. Such utilization is the result of the economic value of hybrid combinations displaying superior yields and qualities as well as stability of performance, of benefits derived in breeding programs, and of the enhanced varietal protection of proprietary rights. No comprehensive and critical analysis of the phenomenon of heterosis in economic plants has been published for the last three decades since the now classical book Heterosis, edited by J . W. Gowen (Iowa State College Press, Ames, Iowa, 1952). The present book attempts to fill the gap and to assess the status of our present knowl edge of the concept, the basis, the extent, and the application of heterosis in economic plants.

This symposium is a follow-up to one held in China in 1986. Since then considerable progress has been made in research and development of hybrid rice. This second international symposium was held under the umbrella of the International Rice Research Conference. Eighty scientists and seed production experts from 18 countries, IRRI and FAO attended. Contributions covered breeding, biotechnology, seed production, agronomy, plant physiology, plant pathology, entomology and economics.

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.

This proceedings is a collection of 46 selected papers that were presented at the 12th International Wheat Genetics Symposium (IWGS). Since the launch of the wheat genome sequencing project in 2005, the arrival of draft genome sequences has marked a new era in wheat genetics and genomics, catalyzing rapid advancement in the field. This book provides a comprehensive review of the forefront of wheat research, across various important topics such as germplasm and genetic diversity, cytogenetics and allopolyploid evolution, genome sequencing, structural and functional genomics, gene function and molecular biology, biotic stress, abiotic stress, grain quality, and classical and molecular breeding. Following an introduction, 9 parts of the book are dedicated to each of these topics. A final, 11th part entitled “Toward Sustainable Wheat Production” contains 7 excellent papers that were presented in the 12th IWGS Special Session supported by the OECD. With rapid population growth and radical climate changes, the world faces a global food crisis and is in need of another Green Revolution to boost yields of wheat and other widely grown staple crops. Although this book focuses on wheat, many of the newly developed techniques and results presented here can be applied to other plant species with large and complex genomes. As such, this volume is highly recommended for all students and researchers in wheat sciences and related plant sciences and for those who are interested in stable food production and food security.
