Under the climate change scenario, frequent occurrence of drought or submergence has been identified as key factor to the low productivity of rice in eastern India. A high yielding, multiple stress (drought, submergence, disease and insect pest) tolerant rice variety, Swarna Samriddhi Dhan (IET 24306) has been released and notified for irrigated as well as rainfed shallow lowland agroecology. This rice variety is a medium duration (135–140 days), high yielding (5.5–6.0 t/ha), with desirable grain and cooking quality traits. It is also suitable for cultivation in water limiting irrigated and drought-prone rainfed areas. Beside drought (reproductive stage) tolerant, it can also tolerate 10–12 days submergence (vegetative stage). This variety shows moderately resistance to leaf blast, brown spot, sheath blight, false smut, stem borer, leaf folder, and gall midge insect pest. Adoption of this variety increases net income of `18000–25000/ha over farmers adopted local cultivars. Swarna Samriddhi Dhan will significantly contribute to increase the rice productivity of irrigated as well as rainfed ecology and alleviate the socio-economic status of farmers of eastern region.
