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. © Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO) 2013.

A very high consumption growth rate has made rice one of the most important crops in Africa, but Africa's rice production growth rate is too low to match the consumption trend. A strong thrust is needed to boost rice production and productivity in Africa, especially in eastern and southern Africa (ESA), where large suitable land areas and resources with a congenial environment are available. Rice breeding activities in ESA, specifically for rainfed lowlands and irrigated ecosystems that have maximum area, did not receive enough attention in the past and hence lag behind in the development of appropriate high-yielding varieties. A poor rice variety development program for rainfed lowlands and irrigated areas was also marred by poor capacity, poor infrastructure, and a lack of proper policy support. This paper discusses the current issues related to the rice breeding scenario and the initiation of breeding support by CGIAR institutes such as IRRI in ESA. © Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO) 2013.
