FUNDAMENTALS OF PLANT BREEDING & GENETICS

Fundamentals of Plant Breeding & Genetics is an essential textbook that offers a thorough and up-to-date exploration of the scientific principles underlying the improvement of crop plants. In an era where global food security is challenged by population growth, climate change, pest and disease pressures, and shrinking arable land, plant breeding stands as a vital tool for developing high-yielding, nutritious, and resilient crop varieties. This book provides readers with a complete journey from the historical roots of plant breeding to the latest advancements in biotechnology and genomics. The text begins by introducing the field, its evolution, objectives, and the role it plays in modern agriculture. It builds a strong foundation in classical genetics through detailed coverage of Mendelian principles, gene interactions, and chromosomal behavior. Readers will gain insights into quantitative genetics, which is crucial for understanding complex traits like yield and stress tolerance that are governed by multiple genes and environmental interactions. Moving into molecular aspects, the book covers DNA structure, gene expression, mutations, and the application of molecular markers in breeding programs. It extensively discusses cytogenetics, including polyploidy, which has played a significant role in the evolution of many crop species. Practical breeding methodologies are emphasized in chapters dedicated to pollination biology, selection methods, hybridization techniques, and heterosis. The integration of modern tools such as tissue culture, genetic engineering, GM crops, and CRISPR-based genome editing demonstrates how biotechnology is revolutionizing traditional breeding approaches. Furthermore, the book addresses critical post-breeding aspects including seed production, variety testing and release, intellectual property rights, and the role of national and international institutions. This holistic approach ensures that readers understand not only the science but also the regulatory and commercial frameworks that govern the deployment of new plant varieties. Written in clear, accessible language with relevant examples, diagrams, and case studies, Fundamentals of Plant Breeding & Genetics is ideal for undergraduate and postgraduate students in agriculture, plant sciences, genetics, and biotechnology. It also serves as a valuable reference for researchers, plant breeders, and extension workers aiming to translate genetic knowledge into practical crop improvement strategies. By mastering the concepts presented in this book, readers will be well-equipped to contribute to sustainable agricultural development and global food security.
