Abstract

Rice is the staple food for more than 60% of Indian population and accounts for 43% of total food grain production and 46% of total cereal production. The present rate of increase in rice production (2000- 09) has slowed down (1.21%) when compared to previous decades (1970-1998 -2.49%, 1999-2000- 1.70%). Hence it becomes imperative to produce more food with the available technologies. Among the innovative options available for enhancing rice production, contribution of hybrid rice offers promise. The gap in food grain production therefore could be met from hybrid rice by exploiting heterosis. Virmani and Edwards (1982) reviewed the status and prospects for breeding hybrid rice and concluded that exploitation of heterosis through hybrid breeding offered an important option to increase yield in this
self-pollinated crop.
