Rice is the most important food crop of the developing world and the demand for it is growing. Provided here is a concise account of hybrid breeding in rice, a newly deployed breeding approach to increase the yield. Research on heterosis, male sterility systems, outcrossing mechanisms, disease/insect management, and grain quality considerations in hybrid rice are reviewed. The book contains a wealth of useful information for practicing hybrid rice breeders, seed producers, researchers, and students of plant breeding.
