This book covers all aspects of hybrid breeding technologies applied for crop improvement in major field crops. The different male sterility systems such as genetic male sterility (GMS), cytoplasmic male sterility (CMS), cytoplasmic and genetic male sterility (CGMS), and male sterility induced by the photoperiod (PGMS), temperature (TGMS), and chemicals are discussed in detail. The different chapters in this book provide a timeline of the key breakthroughs witnessed in the field of plant male sterility technologies, their application in hybrid breeding, and the relevance to the current need for food security. 

In-depth insights into the genetic and regulatory mechanisms of plant male sterility have been presented. This includes discussion on a variety of molecular players that induce male sterility and rescue male fertility in the hybrid plants. To enhance this book’s appeal, more emphasis has been given on the modern emerging approaches such as construction of heterotic pools that could boost hybrid breeding for enhanced crop performance amid climate change and growing population worldwide. 

This book is a guide for growers and industries related to field and horticultural crops. Further, it is a useful reference for plant breeders, researchers and extension workers, and students. The material can also be used for teaching undergraduate and postgraduate courses.

This book provides an overview of various procedures involved in hybrid seed production of field and vegetable crops, including historical development and principles, maintenance of seed purity of parental lines, evolution of breeding systems, male sterility and self-incompatibility. A section of the proposed book is dedicated to quality control procedures, comprising of purity testing, seed testing and certification process, and seed production management. The major shortcomings of the existing systems, new opportunities and future prospects of hybrid seed production are also discussed. The book focuses on field and vegetable crops like rice, maize, pearl millet, sorghum, pigeon pea, rapeseed, mustard, cotton, castor, soybean, and sunflower among others.

This book is for students, researchers, and professionals working in the field of public sectors and commercial seed industries, as well as to other stakeholders who are working to improve their skills on hybrid seed production.
