Opis

Heterosis and Hybrid Seed Production in Agronomic Crops discusses how heterosis or hybrid vigor has played a major role in improving crop productivity and quality in order to feed the ever-increasing human population, particularly in developing countries. Plant breeders, agronomists, seed producers, and farmers will discover why the development of hybrids in the world's major food crops and why the methods of hybrid seed production are critical for achieving this goal. This landmark book deals with heterosis and hybrid seed production of major agronomic crops such as wheat, rice, maize, sorghum, cotton, sunflower, and rapeseed. Through Heterosis and Hybrid Seed Production in Agronomic Crops, you will discover valuable information on hybrid seed production methods that is not available in any other single volume.This unique book contains relevant and essential information about important procedures to help increase crop yield, including: methods for deriving second cycle inbred lines for hybrid maize possibilities for hybrid seed production in wheat techniques of hybrid sorghum seed production production of hybrid seeds using male sterile lines of cotton agronomic management in seed production plots of sunflower seed production technology of hybrid rapeseed advances in hybrid seed production technology of rice in ChinaHeterosis and Hybrid Seed Production in Agronomic Crops gives you a global perspective on essential food crops in all parts of the world. This informative guide will help you use hybrid seed production methods with important agricultural crops and increase the quality of these vital and essential food sources.
