Rice the major principal food crop for the half of the world population. As the world population increases alarmingly, agricultural scientists are striving towards development of an “evergreen revolution” to ensure the food security in the future. To increase the productivity of rice, many deliberate research programmes are being adopted by using all the technologies prevailing currently. Among the all technologies, hybrid development is a popular technology to increase the rice productivity. In the future also these hybrid development technologies will contribute major portion for the food security. The crop scientific community should be ready to face the challenges come from climatic changes viz., high temperature stress, CO2 elevation, etc.,. Hence, the development of the hybrids in the aspect of future climatic factors will help to overcome the food shortages.
