The book Plant Breeding: Principles and Methods was initially designed for B. Sc. (Ag.) students of Indian Universities, and it was extremely well-received by the entire plant breeding community. Gradually, it evolved to its present form, which provides up-to-date information on both conventional and modern approaches to crop improvement. The book has 45 chapters, which are organized in ten parts, and cover various aspects of germplasm conservation and utilization, breeding of self- and cross-pollinated as well as clonal crops, breeding for resistance to biotic and abiotic stresses, special breeding approaches like ideotype, improved quality, polyploidy, biotechnology, molecular markers, etc., evaluation and multiplication of improved strains, national and international organisations for crop improvement, and intellectual property rights. In this edition, two new chapters, viz., ?Novel Plant Breeding Tools? and ?Plant Breeding in Private Sector Environment ? Seed Industry at A Glance for the New Entrant/Aspirant?, have been added to enhance the usefulness of the book. This enlarged edition is expected to be immensely useful to all plant breeding students.
