The varietal development program for rainfed lowland rice, which occupies 17 million hectares in India, has lately received increased attention. Efforts were intensified only during the early 1990s through the launching of different projects, complementary to the national and state programs, to enhance the productivity of this ecosystem. A shuttle-breeding program, a collaborative project between the Indian Council of Agricultural Research and the International Rice Research Institute, provided an opportunity for enhancing the flow of breeding materials of diverse origin among the eastern Indian states to strengthen the breeding program. The materials developed through this project also served as inputs to other breeding programs for this ecosystem. Many promising cultures having a diverse genetic base (15 to 20 parents from different countries), better plant type, and improved sink components have been developed. They have attained 20% higher yield than the best checks and, we hope, will increase the productivity of this ecosystem.
