Hardbound. Zustand: As New. New. Contents Foreword. Preface. 1. Introduction. 2. Techniques of developing hybrids. Conclusion and future line on work. Bibliography. Glossary. India is on the verge of a breakthrough in establishing hybrids on a commercial scale for enhancing the production and productivity of vegetables. Present Government policy to freely import hybrid and boost vegetable production in the country persistent demand of students seed company and farmers keenness to shift to hybrid than traditional seed production and extension workers engaged throughout the country inspire us to bring out this book in most practical style and language. This book gives different approaches to develop the hybrids the techniques involved with different breeding systems have been explained in clarity and illustrations for easy adoption at all levels. The information will be of immense value to the scientist scholars agencies and individuals involved in the development and propagation of hybrids in different vegetable crops. 72 pp.
