Dwivedi, J.L.
Flood-prone rice areas in India are mainly located in various eastem states such as Assam, Bihar, Orissa, Uttar Pradesh, and West Bengal. Of the total of 2.3 million hectares of these lands, eastern Uttar Pradesh has 0.39 million ha. These areas are more vulnerable than the other rainfed ecosystems as their yields are low and quite unstable. In eastem Uttar Pradesh, four different flood-prone subecosystems exist, deep, semideep, flash-flood-prone, and off-season deep stagnant, Many types of rice varieties have been selected by farmers over the centuries that meet the varied and harsh conditions of this ecology. These traditional types give stable but low yields, The IRRI-ICAR-NDUAcTo llaborative project on flood-prone rice established in 1991 resulted in a characterization of the environment followed by strong work on genetic improvement of rice grown in various conditions of this fragile ecology. This paper deals with the accomplishments of this collaboration with IRRI, with special reference to breeding rice for flood-prone, deepwater,and boro areas of eastem Uttar Pradesh. The technologies have significantly helped to increase on-farm productivity, meet household needs, and generate income for resource-poor farmers of the flood-prone areas of eastem Uttar Pradesh.
