- Abstract
Out of the 43.7 million ha of rice area in India, rainfed lowlands constitutes about 17.4 million ha, of which 14.6 million ha are in eastern India. This ecosystem is prone to submergence, water logging and drought, with average yields as low as 1 t ha-1. For improving the genetic yield potential of the rainfed lowland rice varieties of eastern India (Assam, Bihar, Chhattishgarh, Eastern U.P, Odisha and West Bengal), an ICAR-IRRI Collaborative Shuttle Breeding Network was started in 1992 with the main objective to strengthen the rice breeding programmes in eastern India. This review article summarizes the structure and achievements of the past 20 years. Highlights include the identification of three distinct maturity groups, development of elite lines suitable for normal and delayed planting conditions, development of hundreds of advanced breeding lines, and the release of at least 20 varieties. A large number of target traits for the region are also summarized indicating the complexity in developing new varieties for rainfed areas. The outputs produced by the EIRLSBN indicates a successful model for rice breeding partnerships and the benefits of regional and international scientific collaboration for addressing food security.
